Dubai helicopter landmark tour

The day I took a helicopter ride over Dubai, the city felt like it was holding its breath. Heat shimmered off the tarmac around the helipad, and the skyline-those clean angles and brave heights-rose out of the desert like a mirage that willed itself into permanence. Inside the small terminal, the noise of rotors warming up outside seeped in as a low, patient thrum. A staff member guided us through the ritual of flight: a quick weigh-in for seating, valuables tucked into lockers, a safety video that somehow made me calmer. They fastened a slim life vest belt around my waist, handed me a pair of oversized headphones, and asked me to keep my camera strap snug. No loose hats. No wandering on the helipad. Even with the rules, there was a childlike excitement in the room. Everyone smiled with their mouths and their eyes.


Outside, the helicopter crouched like a bird you didn't quite expect to befriend, sleek and efficient, rotors blurring the air into something visible. The pilot greeted us through the headsets once we'd buckled in. His voice, relieved of the wind's mischief, was easy and warm.

He checked that we were comfortable, cracked a joke about the “best office view in the world,” and then the helicopter lifted. The sensation wasn't like a plane rushing forward; it was a careful uncurling from gravity, as if the ground let go of us gently.


The city slid beneath us. What had been tall on foot-towers and highways and billboards-flattened into a pattern. Shapes asserted themselves. The coastline drew a clean arc, and the water pressed right up against Dubai's glass edge, a brilliant lapis band that looked almost painted. On headphones, the pilot began pointing things out: the thread of Sheikh Zayed Road, the symmetry of neighborhoods, mosques with their white domes pricking the grid, the occasional patch of green that insisted on softness in all that geometry.


We drifted toward the coast, and the Burj Al Arab surfaced from the glare like a sail someone had solidified out of the Gulf air. Its shadow cut across the water like a compass needle. Beaches spooled out north and south, pale and orderly; even the umbrellas seemed to align. Down there, people were just arrangements of movement, little freckles of life walking and wading and kicking at soccer balls. A couple of kite surfers sketched long diagonal lines on the sea. It felt impossibly serene to be above it all, the helicopter steady and polite, the world doing what it does without our commentary.


Then the Palm Jumeirah appeared, and the geometry of Dubai's ambition snapped into focus. You can look at photos of the Palm and still not understand how incredibly precise it is until you're right above it. The fronds radiated like pages in a book, villas perched neatly along each finger, pools and gardens modest from this height. The crescent breakwater wrapped the whole pattern in a protective arm. Atlantis stood at the crown in coral pink, theatrical but not ridiculous, its arch framing shards of blue sea. Dubai helicopter ride jumeirah coastline From the sky, the monorail that runs the Palm's spine looked like a toy line. The pilot tilted us slightly so that both sides of the cabin could press their faces at the windows. For a moment, I forgot to take photos. I just stared.


Beyond the Palm, the scatter of the World Islands hovered in the haze. They were startlingly literal: little continents loosening themselves from each other, each with just enough distance to prove the point. They didn't quite resolve into Africa or Europe unless the pilot narrated them for you, but there was a strange pleasure in seeing the idea from this height. Dubai has always felt like a city trying to see itself from above, to build things you can only fully understand with a bird's vantage.

In the helicopter, that idea made sense. It wasn't ostentation as much as choreography.


We banked toward Dubai Marina next. Dubai helicopter ride comfort flight Glass towers arranged themselves around a curve of water like crowds leaning over a railing, watching boats trawl the afternoon. Cayan Tower twisted calmly, as if stretching after a long nap. Along JBR, the beach lounged under a grid of umbrellas; a parasail drifted like a dropped balloon. Ain Dubai, the great wheel on Bluewaters, cut a deliberate circle out of the sky. Roads braided and unbraided beneath us, traffic flowing like mercury. I could see the logic of the city-how neighborhoods were fitted into a plan, how the sea was always within reach, how the desert waited just beyond the last neat line of buildings.


Heading inland, the Burj Khalifa emerged like a needle threading the horizon. It doesn't so much stand above the city as anchor it. Downtown radiated at its feet: the vast sprawl of Dubai Mall, the glittering curve of the fountain lake, and the little drama of the Opera House shaped like a dhow. From up here, the water in the fountain was still, a polished tile waiting for the hour. Dubai helicopter premium city ride You can admire the Burj Khalifa from the ground, the way your neck cranes back until it protests, but meeting it at eye-level-well, almost-reminded me how human it is in its impossibility. The panels caught the sun and winged light in every direction. It looked too thin to be real and too solid to be an illusion.


And then, almost abruptly, the city ended. It's a clean edge: density, density, density, and then open tawny land ruffled by the ghost of wind. From the air, the desert isn't an absence; it's a presence with its own texture, like skin. You can see faint tracks, geometry for another audience. If the Gulf is a mirror, the desert is a memory-soft and stubborn, reminding you how recent the city's rise really is.


On the return leg, the helicopter felt like a living room with better views. The pilot dropped in trivia-a note about the first ships that carried the city's wealth, about how aerial corridors keep flights neatly separated-and left us to the hush of our headphones. Dubai Helicopter Ride . The cabin smelled faintly of plastic and something clean, maybe the AC working hard against the day. Every so often, small vibrations ran through the body of the helicopter, not alarming so much as tactile, like the heartbeat of a big animal you've learned to trust.


Landing was a polite handshake with the ground. Rotor wash rushed over us in warm waves when the doors opened, the city's heat rushing back to reclaim us. We shuffled off grinning, a little dazed, trading the immediate inventory: Did you see that yacht that looked like a spaceship? The way the Palm looked like a stamp? How small the cars were? In the lobby, we glanced through a few preview photos and laughed at the way our faces pressed to the glass.


Later, when I scrolled through my pictures, I realized the photos were good but insufficient. They missed the sense of scale, the hush in your head when you recognize a pattern too big to see from the ground. They couldn't catch the gentle float of liftoff, or the comfort of the pilot's easy narration, or the way the city rearranges itself when you see it whole. Dubai is a place people love to argue about-its audacity, its gloss, its appetite for the superlative. From a helicopter, the argument falls away. You glimpse not the list of world records but the logic that connects them, a city drawing itself with a confident hand between blue water and old sand.


If you go, go early or near sunset, when the light is kind and the air is clear. Wear dark clothes to help with reflections, press your lens right up to the window, and don't sweat the seat assignment-balance matters, and the pilots make sure everyone gets a view. Mostly, though, let yourself look without worrying about the shot. There are places where the best souvenir is the memory of the shape of things, held briefly in your mind, as the helicopter lifts you into a calmer version of the sky.

The Burj Khalifa[a] (known as the Burj Dubai before its inauguration) is a megatall skyscraper in Dubai, United Arab Emirates. Designed by Skidmore, Owings & Merrill, it is the world's tallest structure, with a total height of 829.8 m (2,722 ft, or just over half a mile) and a roof height (excluding the antenna, but including a 242.6 m spire)[2] of 828 m (2,717 ft). It has also been the tallest building in the world since its topping out in 2009, surpassing Taipei 101, which had held the record for a half-decade.[3][4]

Construction of the Burj Khalifa began in 2004; the exterior was completed five years later. The primary structure is reinforced concrete. Some of the structural steel for the building was salvaged from the demolished Palace of the Republic in East Berlin.[5] The building was opened in 2010 as part of a new development called Downtown Dubai. It was designed to be the centerpiece of large-scale, mixed-use development.

The building is named after the former president of the United Arab Emirates (UAE), Sheikh Khalifa bin Zayed Al Nahyan.[6] The United Arab Emirates government provided Dubai with financial support as the developer, Emaar Properties, experienced financial problems during the Great Recession. Then-president of the United Arab Emirates, Khalifa bin Zayed, organized federal financial support. For his support, Mohammad bin Rashid, Ruler of Dubai, changed the name from "Burj Dubai" to "Burj Khalifa" during inauguration.

The design is derived from the Islamic architecture of the region, such as in the Great Mosque of Samarra. The Y-shaped tripartite floor geometry is designed to optimise residential and hotel space. A buttressed central core and wings are used to support the height of the building. The Burj Khalifa's central core houses all vertical transportation except egress stairs within each of the wings.[7] The structure also features a cladding system which is designed to withstand Dubai's hot summer temperatures.[8] It contains a total of 57 elevators and 8 escalators.

Development

[edit]

Construction began on 12 January 2004, with the exterior of the structure completed on 1 October 2009. The building officially opened on 4 January 2010[9][10] and is part of the 2 km2 (490 acres) Downtown Dubai development at the 'First Interchange' along Sheikh Zayed Road, near Dubai's main business district.[citation needed]

The tower's architecture and engineering were performed by Skidmore, Owings & Merrill of Chicago, with Adrian Smith as chief architect, and Bill Baker as a chief structural engineer.[11][12] The firm had designed the Sears Tower in Chicago, a previous record holder for the world's tallest building.[13]

Hyder Consulting was supervising engineer and NORR Group Consultants supervised the architecture. The primary contractor was Samsung C&T of South Korea, together with the Belgian group BESIX and the local company Arabtec.[14]

Numerous complaints concerned migrant workers from South Asia, the primary building labour force, who were paid low wages and sometimes had their passports confiscated.[15]

Conception

[edit]

Burj Khalifa was designed to be the centerpiece of a large-scale, mixed-use development to include 30,000 homes,[16] nine hotels (including The Address Downtown Dubai), 3 hectares (7.4 acres) of parkland, at least 19 residential skyscrapers, the Dubai Mall, and the 12-hectare (30-acre) artificial Burj Khalifa Lake. The decision to build Burj Khalifa was reportedly based on the government's decision to diversify from an oil-based economy to one that is service and tourism based. According to officials, projects like Burj Khalifa needed to be built to garner more international recognition and hence investment. "He (Sheikh Mohammed bin Rashid Al Maktoum) wanted to put Dubai on the map with something really sensational," said Jacqui Josephson, a tourism and VIP delegations executive at Nakheel Properties.[17]

The tower was known as Burj Dubai ("Dubai Tower") until its official opening in January 2010.[18] It was renamed in honour of the ruler of Abu Dhabi, Khalifa bin Zayed Al Nahyan; Abu Dhabi and the federal government of UAE lent Dubai tens of billions of US dollars so that Dubai could pay its debts – Dubai borrowed at least $80 billion for construction projects.[18] In the 2000s, Dubai started diversifying its economy but it suffered from the 2008 financial crisis and the Great Recession, leaving large-scale projects already in construction abandoned.[19]

Records

[edit]

The Burj Khalifa set several world records, including:

Architecture and design

[edit]
A cross-section of comparisons of various towers, from ground level from top to bottom: Burj Khalifa, Taipei 101, Willis Tower, and the original World Trade Center

The tower was designed by Skidmore, Owings, and Merrill (SOM), which also designed the Willis Tower (formerly the Sears Tower) in Chicago and the One World Trade Center in New York City. Burj Khalifa uses the bundled tube design of the Willis Tower, invented by Fazlur Rahman Khan.[32][33] Due to its tubular system, proportionally only half the amount of steel was used in the construction, compared to the Empire State Building.[32][34] Khan's contributions to the design of tall buildings have had a profound impact on architecture and engineering. It would be difficult to find any worldwide practices in the design of tall buildings that have not been directly or indirectly influenced by his work.[35] The design is reminiscent of Frank Lloyd Wright's vision for The Illinois, a mile-high skyscraper designed for Chicago, as well as Chicago's Lake Point Tower. When Adrian Smith was conceiving the project at SOM, he looked out his office window toward Lake Point Tower's curved three-wing layout and thought, "There's the prototype".[36] According to Strabala, Burj Khalifa was designed based on the 73 floor Tower Palace Three, an all-residential building in Seoul. In its early planning, Burj Khalifa was intended to be entirely residential.[37]

After the original design by Skidmore, Owings, and Merrill, Emaar Properties chose Hyder Consulting to be the supervising engineer and NORR Group Consultants International Ltd to supervise the architecture of the project.[38] Hyder was selected for their expertise in structural and MEP (mechanical, electrical and plumbing) engineering.[39] Hyder Consulting's role was to supervise construction, certify the architect's design, and be the engineer and architect of record to the UAE authorities.[38] NORR's role was the supervision of all architectural components including on-site supervision during the construction and design of a 6-storey addition to the office annex building for architectural documentation. NORR was also responsible for the architectural integration drawings for the Armani Hotel included in the Tower. Emaar Properties also engaged GHD,[40] an international multidisciplinary consulting firm, to act as an independent verification and testing authority for concrete and steelwork.

The design is derived from Islamic architecture.[22] As the tower rises from the flat desert base, there are 27 setbacks in a spiral pattern, decreasing the cross-section of the tower as it rises and creating convenient outdoor terraces. These setbacks are arranged and aligned in a way that minimizes vibration wind loading from eddy currents and vortices.[7] At the top, the central core emerges and is sculpted to form a finishing spire. At its tallest point, the tower sways a total of 1.5 m (4.9 ft).[41]

The spiral minaret at the Great Mosque of Samarra

The spire of Burj Khalifa is composed of more than 4,000 tonnes (4,400 short tons; 3,900 long tons) of structural steel. The central pinnacle pipe weighs 350 tonnes (390 short tons; 340 long tons) and has a height of 200 m (660 ft). The spire also houses communications equipment.[42] This 244-metre (801 ft) spire is widely considered vanity height, since very little of its space is usable. Without the spire, Burj Khalifa would be 585 metres (1,919 ft) tall. This was reported in a Council on Tall Buildings and Urban Habitat study, which notes that the empty spire "could be a skyscraper on its own".[2] Such a skyscraper, if located in Europe, would be the 11th tallest building on that continent.[43]

In 2009 architects announced that more than 1,000 pieces of art would adorn the interiors of Burj Khalifa, while the residential lobby of Burj Khalifa would display the work of Jaume Plensa.[44]

The cladding system consists of 142,000 m2 (1,528,000 sq ft) of more than 26,000 reflective glass panels and aluminium and textured stainless steel spandrel panels with vertical tubular fins.[42] The architectural glass provides solar and thermal performance as well as an anti-glare shield for the intense desert sun, extreme desert temperatures and strong winds. The glass covers more than 174,000 m2 (1,870,000 sq ft) in area.[citation needed] The Burj's typical curtain wall panels measure 4 ft 6 in (1.4 m) wide by 10 ft 8 in (3.3 m) high and weigh about 800 pounds (360 kg) each, with wider panels near the building's edges and taller ones near the top.[45]

The exterior temperature at the top of the building is thought to be 6 °C (11 °F) cooler than at its base.[46][needs update]

A 304-room Armani Hotel, the first of 4 by Armani, occupies 15 of the lower 39 floors.[3][47] The hotel was supposed to open on 18 March 2010,[48][49] but after several delays, it finally opened to the public on 27 April 2010.[50] The corporate suites and offices were also supposed to open from March onwards,[51] yet the hotel and observation deck remained the only parts of the building which were open in April 2010.

The sky lobbies on the 43rd and 76th floors house swimming pools.[52] Floors 20 through 108 have 900 private residential apartments (which, according to the developer, sold out within eight hours of being on the market). An outdoor zero-entry swimming pool is located on the 76th floor of the tower. Corporate offices and suites fill most of the remaining floors, except for the 122nd, 123rd, and 124th, where the At.mosphere restaurant, sky lobby, and an indoor and outdoor observation deck are located respectively. In January 2010, it was planned that Burj Khalifa would receive its first residents in February 2010.[52][53]

The building has 57 elevators and 8 escalators.[42] The elevators have a capacity of 12 to 14 people per cabin, and include the world's fastest double-deck elevators, rising and descending at up to 10 m/s (33 ft/s). Engineers initially considered installing the world's first triple-deck elevators.[25] The double-deckers are equipped with LCD displays to amuse visitors during their travel to the observation deck.[54] The building has 2,909 stairs from the ground floor to the 160th floor.[55]

Plumbing systems

[edit]

The Burj Khalifa's water system supplies an average of 946,000 L (250,000 U.S. gal) of water per day through 100 km (62 mi) of pipes.[22][56] An additional 213 km (132 mi) of piping serves the fire emergency system, and 34 km (21 mi) supplies chilled water for the air conditioning system.[56]

Air conditioning

[edit]

The air conditioning system draws air from the upper floors where the air is cooler and cleaner than on the ground.[57] At peak cooling times, the tower's cooling is 46 MW (62,000 hp), equivalent to that provided by 13,000 short tons (26,000,000 lb; 12,000,000 kg) of melting ice in one day.[56] Water is collected via a condensate collection system and is used to irrigate the nearby park.[22]

Window cleaning

[edit]

To wash the 24,348 windows, totaling 120,000 m2 (1,290,000 ft2) of glass, the building has three horizontal tracks, each holding a 1,500 kg (3,300 lb) bucket machine. Above level 109, and up to tier 27, traditional cradles from davits are used. The top of the building is cleaned by a crew that uses ropes to descend from the top to gain access.[58][59] Under normal conditions, when all building maintenance units are operational, it takes 36 workers three to four months to clean the entire exterior.[42][60]

Unmanned machines clean the top 27 additional tiers and the glass spire. The cleaning system was developed in Melbourne, Australia, by CoxGomyl, a manufacturer of building maintenance units,[61] at a cost of A$8 million.[60]

Features

[edit]

Fountain

[edit]
The Dubai Fountain

Outside the Burj Khalifa, WET Enterprises designed a fountain system at a cost of Dh 800 million (US$217 million). Illuminated by 6,600 lights and 50 coloured projectors, it is 270 m (900 ft) long and shoots water 150 m (500 ft) into the air while accompanied by a range of classical to contemporary Arabic and other music. It is the world's largest choreographed fountain.[62] On 26 October 2008, Emaar announced that based on results of a naming contest the fountain would be called the Dubai Fountain.[63]

Observation deck

[edit]

View from the observation deck

An outdoor observation deck, named At the Top, opened on 5 January 2010 on the 124th floor, at 452 m (1,483 ft).[64] It opened the 148th floor SKY level at 555 m (1,821 ft), giving it the highest observation deck in the world on 15 October 2014.[65][66] However, in June 2016 the Shanghai Tower opened with an observation deck at a height of 561 metres, thus taking the title of the world's highest observation deck. Subsequently, the Burj Khalifa reclaimed the record on February 18, 2019, when it opened The Lounge observatory at 585 m (1,919 ft), which is also the highest lounge in the world.[67]

The Burj Khalifa's 124th floor observation deck also features a so-called electronic telescope, an augmented reality device developed by Gsmprjct° of Montréal, which allows visitors to view the surrounding landscape in real-time, and to view previously saved images such as those taken at different times of day or under different weather conditions.[68][69][70] To reduce the daily rush of sightseers, management allows visitors to purchase tickets in advance for a specific date and time, at a 75% discount on tickets purchased on the spot.[71]

On 8 February 2010, the observation deck was closed to the public for two months after power-supply problems caused an elevator to become stuck between floors, trapping a group of tourists for 45 minutes.[72][73][74][75][76]

When the tide is low and visibility is high, people can see the shores of Iran (which is around 153 km or 95 mi away) from the top of the skyscraper.[77]

Park

[edit]

Burj Khalifa is surrounded by an eleven-hectare (27-acre) park designed by landscape architects SWA Group.[78] Like the tower, the park's design was based on the flower of the Hymenocallis, a desert plant.[79] At the centre of the park is the water room, which is a series of pools and water jet fountains. Benches and signs incorporate images of Burj Khalifa and the Hymenocallis flower.[80]

The plants are watered by water collected from the building's cooling system. The system provides 68,000,000 L (18,000,000 US gal) annually.[80] WET Enterprises, who also developed the Dubai Fountain, developed the park's six water features.[81]

Construction

[edit]
Animation of construction process
Aerial closeup of Burj Khalifa under construction in March 2008

The tower was constructed by Samsung C&T from South Korea, which also did work on the Petronas Twin Towers and Taipei 101.[85] Samsung C&T built the tower in a joint venture with BESIX from Belgium and Arabtec from the UAE.[86][87] Turner was the project manager on the main construction contract.[88] Hong Kong-based Far East Aluminium combined to provide the exterior cladding for Burj Khalifa.[89][90]

The contractor and the engineer of record was Hyder Consulting.[91] Under UAE law, the contractor and the engineer of record is jointly and severally liable for the performance of Burj Khalifa.

The primary structure is reinforced concrete. Putzmeister created a new, super high-pressure trailer concrete pump, the BSA 14000 SHP-D, for this project.[24] Burj Khalifa's construction used 330,000 m3 (431,600 cu yd) of concrete and 55,000 tonnes (61,000 short tons; 54,000 long tons) of steel rebar, and construction took 22 million man-hours.[11] In May 2008 Putzmeister pumped concrete with more than 21 MPA ultimate compressive strength of gravel to surpass the 600 metres weight of the effective area of each column from the foundation to the next 4th level, and the rest was by metal columns jacketed or covered with concrete to a then world record delivery height of 606 m (1,988 ft),[24] the 156th floor. Three tower cranes were used during the construction of the uppermost levels, each capable of lifting a 25-tonne load.[92] The remaining structure above was constructed of lighter steel.

In 2003, 33 test holes were drilled to study the strength of the bedrock underlying the structure.[93] "Weak to very weak sandstone and siltstone" was found, just metres below the surface.[94] Samples were taken from test holes drilled to a depth of 140 metres, finding weak to very weak rock all the way.[95] The study described the site as part of a "seismically active area".[citation needed] Another challenging element was the shamal which often creates sandstorms.[20]

Over 45,000 m3 (58,900 cu yd) of concrete, weighing more than 110,000 tonnes (120,000 short tons; 110,000 long tons) were used to construct the concrete and steel foundation, which features 192 piles; each pile is 1.5 metre in diameter by 43 m in length, buried more than 50 m (164 ft) deep.[25] The foundation was designed to support the total building weight of approximately 450,000 tonnes (500,000 short tons; 440,000 long tons). This weight was then divided by the compressive strength of concrete which is 30 MPa which yielded 450 sq. metres of vertical normal effective area, which then yielded 12 metres by 12 metres dimensions.[96] A cathodic protection system is under the concrete to neutralise the sulphate and chloride-rich groundwater and prevent corrosion.[42][20]

During the construction of the Burj Khalifa, over 35,000 tonnes of structural steel was obtained from the Palace of the Republic in Berlin, which had served as the parliament building for the Volkskammer of the former East Germany. The steel was shipped to Dubai after the Palace's demolition was completed in 2008.[5]

The Burj Khalifa is highly compartmentalised. Pressurised, air-conditioned refuge floors are located every 13 floors (on floors G, 13, 26, 39, 52, etc.) where people can shelter on their long walk down to safety in case of an emergency or fire.[42][97]

Special mixes of concrete were made to withstand the extreme pressures of the massive building weight; as is typical with reinforced concrete construction, each batch of concrete was tested to ensure it could withstand certain pressures. CTLGroup, working for Skidmore, Owings and Merrill, conducted the creep and shrinkage testing critical for the structural analysis of the building.[98]

The consistency of the concrete used in the project was essential. It was difficult to create a concrete that could withstand both the thousands of tonnes bearing down on it and Persian Gulf temperatures that can reach 50 °C (122 °F). To combat this problem, the concrete was not poured during the day. Instead, during the summer months, ice was added to the mixture and it was poured at night when the air was cooler and the humidity was higher. Cooler concrete cures more evenly and is, therefore, less likely to set too quickly and crack. Any significant cracks could have put the entire project in jeopardy.[99][100][101][102][103]

Real estate values

[edit]

In March 2009, Mohamed Ali Alabbar, chairman of the project's developer, Emaar Properties, said office space pricing at Burj Khalifa reached US$4,000 per sq ft (over US$43,000 per m2) and the Armani Residences, also in Burj Khalifa, sold for US$3,500 per sq ft (over US$37,500 per m2).[114] He estimated the total cost for the project to be about US$1.5 billion.[6]

The project's completion coincided with the Great Recession, and with vast overbuilding in the country, leading to high vacancies and foreclosures.[115] With Dubai mired in debt from its huge ambitions, the government was forced to seek multibillion-dollar bailouts from its oil-rich neighbor Abu Dhabi. Subsequently, in a surprise move at its opening ceremony, the tower was renamed Burj Khalifa, said to honour the UAE President Khalifa bin Zayed Al Nahyan for his crucial support.[4][116]

Because of the slumping demand in Dubai's property market, the rents in the Burj Khalifa plummeted 40% some ten months after its opening. Out of 900 apartments in the tower, 825 were still empty at that time.[117][118] Over the next 30 months, overseas investors steadily bought up available apartments and office space.[119] By October 2012, Emaar reported that around 80% of the apartments were occupied.[120]

Official launch ceremony

[edit]
The opening ceremony of Burj Khalifa

The ceremony was broadcast live on a giant screen on Burj Park Island and on smaller screens elsewhere.[121] Hundreds of media outlets from around the world reported live from the scene.[122] In addition to the media presence, 6,000 guests were expected.[123]

The opening was held on 4 January 2010.[124] The ceremony featured a display of 10,000 fireworks, light beams projected on and around the tower, and further sound, light and water effects.[122] The celebratory lighting was designed by UK lighting designers Speirs and Major Associates.[125] Using the 868 powerful stroboscope lights that are integrated into the façade and spire of the tower, different lighting sequences were choreographed, together with more than 50 different combinations of other effects.[citation needed]

Controversies

[edit]

Incidents

[edit]

On 10 May 2011, an Asian migrant worker in his mid-30s jumped to his death from the 147th floor onto the 108th floor's deck. Dubai police said he killed himself because his company refused to let him leave the country.[126]

On 18 May 2015, Dubai police disputed a report that a Portuguese tourist named Laura Vanessa Nunes fell to her death from the Burj Khalifa the prior 16 November, claiming that she fell from the Jumeirah Lake Towers.[127][128] Nine News obtained emails from Portugal's embassy in the UAE under freedom of information laws, which indicated that the female tourist jumped from the 148th floor of the Burj Khalifa.[129]

Labour

[edit]

The Burj Khalifa was built primarily by workers from South Asia and East Asia.[130][131] This is generally because the current generation of UAE locals prefer governmental jobs and do not have an attitude favouring private sector employment.[132][133] On 17 June 2008, there were about 7,500 skilled workers employed at the construction site.[109] Press reports indicated in 2006 that skilled carpenters at the site earned £4.34 a day, and labourers earned £2.84.[130] According to a BBC investigation and a Human Rights Watch report, the workers were housed in abysmal conditions, and worked long hours for low pay.[134][135][136] During construction, one construction-related death was reported.[137] Workplace injuries and deaths in the UAE are poorly documented, according to Human Rights Watch.[134]

In March 2006 about 2,500 workers, upset over buses that were delayed for the end of their shifts, protested and triggered a riot, damaging cars, offices, computers, and construction equipment.[130] A Dubai Interior Ministry official said the rioters caused almost £500,000 in damage.[130] Most of the workers involved in the riot returned the following day but refused to work.[130]

New Year's Eve

[edit]

Emaar New Year's Eve is an annual event held every 31 December at Burj Khalifa, organised by Emaar Properties.[138][139] The event consists of fireworks launched from Burj Khalifa, a light and laser show on the facade of Burj Khalifa, and an accompanying soundtrack and a special fountain show on The Dubai Fountain choreographed to the soundtrack.[140][141] The Emaar New Year's Eve fireworks celebration originated in 2010 with the inauguration of the world's tallest building, Burj Khalifa. The celebration was broadcast live to more than 2 million people and lasted for 3 minutes.[142]

Since 2011, national live broadcasting rights have been held by Dubai Media Incorporated and Dubai TV.[142]

Emaar New Year's Eve has won two Guinness World Records, including "Largest LED-Illuminated Facade" in 2015 and 2019.[143][144][145]

In 2017 and 2018, Emaar New Year's Eve was broadcast live on Twitter,[146][147] and YouTube. In 2020, it was broadcast live for the first time on Zoom.[148]

In 2021, Emaar celebrated solidarity in honour of frontline workers of the COVID-19 pandemic.[149]

For the 2022 event, a laser feature was installed on The Dubai Fountain in sync with the Burj Khalifa's laser and fireworks show.[150]

BASE jumping

[edit]

The building has been used by several experienced BASE jumpers for authorised and unauthorised BASE jumping:

In May 2008, Hervé Le Gallou and David McDonnell, dressed as engineers, entered Burj Khalifa (around 650 metres (2,130 ft) at the time), and jumped off a balcony situated several floors below the 160th floor.[151][152]

On 8 January 2010, with permission of the authorities, Nasr Al Niyadi and Omar Al Hegelan, from the Emirates Aviation Society, broke the world record for the highest BASE jump from a building after they leapt from a crane-suspended platform attached to the 160th floor at 672 m (2,205 ft). The two men descended the vertical drop at a speed of up to 220 km/h (140 mph), with enough time to open their parachutes 10 seconds into the 90-second jump.[153][154]

On 21 April 2014, with permission of the authorities and support from several sponsors, highly experienced French BASE jumpers Vince Reffet and Fred Fugen broke the Guinness world record for the highest BASE jump from a building after they leapt from a specially designed platform, built at the very top of the pinnacle, at 828 metres (2,717 feet).[155][156][157]

Climbing

[edit]

On 28 March 2011, Alain "Spiderman" Robert scaled the outside of Burj Khalifa. The climb to the top of the spire took 6 hours. To comply with UAE safety laws, Robert, who usually climbs in free solo style, used a rope and harness.[158]

Awards

[edit]

In June 2010, Burj Khalifa was the recipient of the 2010 "Best Tall Building Middle East & Africa" award by the Council on Tall Buildings and Urban Habitat.[159] On 28 September 2010 Burj Khalifa won the award for the best project of the year at the Middle East Architect Awards 2010.[160] Awards Chair Gordon Gill, of Adrian Smith + Gordon Gill Architecture, said:

We are talking about a building here that has changed the landscape of what is possible in architecture – a building that became internationally recognized as an icon long before it was even completed. 'Building of the Century' was thought a more apt title for it.[161]

Burj Khalifa was also the recipient of the following awards.[162][163]

The Jumeirah Burj Al Arab (Arabic: برج العرب, lit.'Arab Tower'), commonly known as Burj Al Arab, is a luxury hotel in Dubai, United Arab Emirates.[8] Developed and managed by Jumeirah, it is one of the tallest hotels in the world, although 39% of its total height is made up of non-occupiable space.[9][10][11] Burj Al Arab stands on an artificial island that is 280 m (920 ft) from Jumeirah Beach and is connected to the mainland by a private curving bridge. The shape of the structure is designed to resemble the sail of a dhow.[12] It has a helipad near the roof, at a height of 210 m (689 ft) above ground.

Site

[edit]

The beachfront area where Jumeirah Burj Al Arab and Jumeirah Beach Hotel are located was previously called Chicago Beach.[13] The hotel is located on an island of reclaimed land, 280 m (920 ft) offshore of the beach of the former Chicago Beach Hotel. The former hotel was demolished during the construction of the Burj Al Arab.[14] The locale's name had its origins in the Chicago Bridge & Iron Company, which at one time welded giant floating oil storage tanks, known locally as Kazzans, on the site.[13]

History

[edit]

The Burj Al Arab was designed by the British multidisciplinary consultancy Atkins, led by architect Tom Wright of WKA. He came up with the iconic design and signature translucent fiberglass facade that serves as a shield from the desert sun during the day and as a screen for illumination at night.[15] The design and construction were managed by Canadian engineer Rick Gregory, and construction managed by David Kirby also of WS Atkins. The Burj Al Arab's interior is by British-Chinese designer Khuan Chew. Construction of the island began in 1994 and involved up to 2,000 construction workers during peak construction. Two "wings" spread in a V to form a vast "mast", while the space between them is enclosed in a massive atrium. The setting of a high rise building on saturated soil and the novelty of the project required groundbreaking dynamic analysis and design to take into consideration soil-structure interaction, effect of water, high winds, and helipad among other loads, to help finalize the design and take the project into construction.[16][failed verification]

The hotel was built by South African construction contractor Murray & Roberts, now renamed Concor and Al Habtoor Engineering. The interior designs were led and created by Khuan Chew and John Carolan of KCA international and delivered by UAE based Depa Group.[17]

The building opened on 1 December 1999.[1] The New Year's Eve fireworks celebration originated in 2000 with the inauguration of the United Arab Emirates.

The hotel's helipad was designed by Irish architect Rebecca Gernon.[18] The helipad is at the building's 28th floor, and the helipad been used as a car race track, a boxing ring, has hosted a tennis match, and the jumping off point for the highest kite surfing jump in history.[19]

In 2017, the hotel hosted the wedding of Daniel Kinahan, head of the Kinahan Organized Crime Group.[20] The wedding was attended by several prominent drug traffickers, such as Ridouan Taghi, Edin Gačanin, 'Ricardo (El Rico) Riquelme Vega, and Raffaele Imperiale.[20]

Features

Several features of the hotel required complex engineering feats to achieve. The hotel rests on an artificial island constructed 280 m (920 ft) offshore. To secure a foundation, the builders drove 230 40-metre-long (130 ft) concrete piles into the sand by drilling method.[21]

Engineers created a ground surface layer of large rocks, which is circled with a concrete honeycomb pattern, which serves to protect the foundation from erosion. It took three years to reclaim the land from the sea, while it took less than three years to construct the building itself. The building contains over 70,000 m3 (92,000 yd3) of concrete and 9,000 tons of steel.[21]

Inside the building, the atrium is 180 m (590 ft) tall.[22]

Given the height of the building, the Burj Al Arab is the world's fifth tallest hotel after Gevora Hotel, JW Marriott Marquis Dubai, Four Seasons Place Kuala Lumpur and Rose and Rayhaan by Rotana. But if buildings with mixed use were stripped off the list, the Burj Al Arab would be the world's third tallest hotel. The structure of the Rose Rayhaan, also in Dubai, is 333 metres (1,093 ft) tall,[23] 12 m (39 ft) taller than the Burj Al Arab, which is 321 metres (1,053 ft) tall.[23]The Burj Al Arab's helipad, located 210 meters above ground, has been the site of several high-profile events, including a tennis match between Roger Federer and Andre Agassi, and stunts by Red Bull athletes.[citation needed]

Rooms and suites

[edit]

The hotel is managed by the Jumeirah Group. The hotel has 199 exclusive suites each allocated eight dedicated staff members and a 24-hour butler service.[24] The smallest suite occupies an area of 169 m2 (1,820 sq ft), the largest covers 780 m2 (8,400 sq ft).[25]

The Royal Suite, billed at US$24,000 per night, is listed at number 12 on World's 15 most expensive hotel suites compiled by CNN Go in 2012.[26]

The Burj Al Arab is very popular with the Chinese market, which made up 25 percent of all bookings at the hotel in 2011 and 2012.[27]

Restaurants

[edit]
Al Muntaha
Al Mahara

There are six restaurants in the hotel, including:

Al Muntaha ("The Ultimate"), is located 200 m (660 ft) above the Persian Gulf, offering a view of Dubai. It is supported by a full cantilever that extends 27 m (89 ft) from either side of the mast, and is accessed by a panoramic elevator.[citation needed]

Al Mahara ("Oyster"), which is accessed via a simulated submarine voyage, features a large seawater aquarium, holding roughly 990,000 L (260,000 US gal) of water. The wall of the tank, made of acrylic glass in order to withstand the water pressure, is about 18 cm (7.1 in) thick.[citation needed]

Rating

[edit]

While the hotel has sometimes been described as "the world's only 'seven-star' hotel", the hotel management claims never to have done so themselves. The term appeared due to a British journalist who had visited the hotel on a tour before it was officially opened. The journalist described Burj al Arab as "more than anything she has ever seen" and therefore referred to it as a seven-star hotel.[28] A Jumeirah Group spokesperson said "There's not a lot we can do to stop it. We're not encouraging the use of the term. We've never used it in our advertising."[29]

Reception

[edit]

Burj Al Arab has attracted criticism as "a contradiction of sorts, considering how well-designed and impressive the construction ultimately proves to be."[25] The contradiction here seems to be related to the hotel's decor. "This extraordinary investment in state-of-the-art construction technology stretches the limits of the ambitious urban imagination in an exercise that is largely due to the power of excessive wealth." Another critic includes negative critiques for the city of Dubai as well: "both the hotel and the city, after all, are monuments to the triumph of money over practicality. Both elevate style over substance."[25] Yet another: "Emulating the quality of palatial interiors, in an expression of wealth for the mainstream, a theater of opulence is created in Burj Al Arab ... The result is a baroque effect".[25]

[edit]

The last chapter of the espionage novel Performance Anomalies[30][31] takes place at the top of the Burj Al Arab,[32] where the spy protagonist Cono 7Q discovers that through deadly betrayal his spy nemesis Katerina has maneuvered herself into the top echelon of the government of Kazakhstan. The hotel can also be seen in Syriana and also some Bollywood movies.[which?]

Richard Hammond included the building in his television series Richard Hammond's Engineering Connections.

The Jumeirah Burj Al Arab serves as the cover image for the 2009 album Ocean Eyes by Owl City.

The Burj Al Arab was the site of the last task of the fifth episode of the first season of the Chinese edition of The Amazing Race, where teams had to clean up a room to the hotel's standards.[33][34]

The building is featured in Matthew Reilly's novel The Six Sacred Stones, where a kamikaze pilot crashes a plane into the hotel, destroying it in an attempt to kill the protagonist, Jack West Jr.

The building was the location of the main challenge of the ninth episode of the Canadian-American animated television series Total Drama Presents: The Ridonculous Race,[35] where contestants were tasked to either return a serve from a tennis robot on the hotel's helipad, or squeegee an entire column of the hotel's windows.

A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally.[1] These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of short take-off and landing (STOL) or short take-off and vertical landing (STOVL) aircraft cannot perform without a runway.

The Focke-Wulf Fw 61 was the first successful, practical, and fully controllable helicopter in 1936, while in 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production. Starting in 1939 and through 1943, Igor Sikorsky worked on the development of the VS-300, which over four iterations, became the basis for modern helicopters with a single main rotor and a single tail rotor.

Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most common helicopter configuration. However, twin-rotor helicopters (bicopters), in either tandem or transverse rotors configurations, are sometimes in use due to their greater payload capacity than the monorotor design, and coaxial-rotor, tiltrotor and compound helicopters are also all flying today. Four-rotor helicopters (quadcopters) were pioneered as early as 1907 in France, and along with other types of multicopters, have been developed mainly for specialized applications such as commercial unmanned aerial vehicles (drones) due to the rapid expansion of drone racing and aerial photography markets in the early 21st century, as well as recently weaponized utilities such as artillery spotting, aerial bombing and suicide attacks.

Etymology

[edit]

The English word helicopter is adapted from the French word hélicoptère, coined by Gustave Ponton d'Amécourt in 1861, which originates from the Greek helix (ἕλιξ), genitive helikos (ἕλῐκος), "helix, spiral, whirl, convolution"[2] and pteron (πτερόν) "wing".[3][4] In a process of rebracketing, the word is often (erroneously, from an etymological point of view) perceived by English speakers as consisting of heli- and -copter, leading to words like helipad and quadcopter.[5][6] English language nicknames for "helicopter" include "chopper", "copter", "heli", and "whirlybird". In the United States military, the common slang is "helo" pronounced /ˈhiː.loʊ/.

Design

[edit]
Main and anti-torque rotors

A helicopter is a type of rotorcraft in which lift and thrust are supplied by one or more horizontally-spinning rotors.[7] By contrast the autogyro (or gyroplane) and gyrodyne have a free-spinning rotor for all or part of the flight envelope, relying on a separate thrust system to propel the craft forwards, so that the airflow sets the rotor spinning to provide lift. The compound helicopter also has a separate thrust system, but continues to supply power to the rotor throughout normal flight.[citation needed] U.S. federal regulations state that "helicopter" means a rotorcraft that, for its horizontal motion, depends principally on its engine-driven rotors.[8]

Rotor system

[edit]

The rotor system, or more simply rotor, is the rotating part of a helicopter that generates lift. A rotor system may be mounted horizontally, as main rotors are, providing lift vertically, or it may be mounted vertically, such as a tail rotor, to provide horizontal thrust to counteract torque from the main rotors. The rotor consists of a mast, hub and rotor blades.[citation needed]

The mast is a cylindrical metal shaft that extends upwards from the transmission. At the top of the mast is the attachment point for the rotor blades called the hub. Main rotor systems are classified according to how the rotor blades are attached and move relative to the hub. There are three basic types: hingeless, fully articulated, and teetering; although some modern rotor systems use a combination of these.[citation needed]

Anti-torque

[edit]
Sikorsky's V-300, 1937

Most helicopters have a single main rotor, but torque created by its aerodynamic drag must be countered by an opposed torque. The design that Igor Sikorsky settled on for his VS-300 was a smaller tail rotor. The tail rotor pushes or pulls against the tail to counter the torque effect, and this has become the most common configuration for helicopter design, usually at the end of a tail boom.[citation needed]

Some helicopters use other anti-torque controls instead of the tail rotor, such as the ducted fan (called Fenestron or FANTAIL) and NOTAR. NOTAR provides anti-torque similar to the way a wing develops lift through the use of the Coandă effect on the tail boom.[9]

MD 520N NOTAR

The use of two or more horizontal rotors turning in opposite directions is another configuration used to counteract the effects of torque on the aircraft without relying on an anti-torque tail rotor. This allows the power normally required to be diverted for the tail rotor to be applied fully to the main rotors, increasing the aircraft's power efficiency and lifting capacity. There are several common configurations that use the counter-rotating effect to benefit the rotorcraft:

  • Tandem rotors are two counter-rotating rotors with one mounted behind the other.[10]
  • Transverse rotors are pair of counter-rotating rotors transversely mounted at the ends of fixed wings or outrigger structures. Now used on tiltrotors, some early model helicopters had used them.
  • Coaxial rotors are two counter-rotating rotors mounted one above the other with the same axis.
  • Intermeshing rotors are two counter-rotating rotors mounted close to each other at a sufficient angle to let the rotors intermesh over the top of the aircraft without colliding. An aircraft utilizing this is known as a synchropter.
  • Multirotors make use of three or more rotors. Specific terms are also used depending on the exact amount of rotors, such as tricopter, quadcopter, hexacopter and octocopter for three rotors, four rotors, six rotors and eight rotors respectively, of which quadcopter is the most common. Multirotors are primarily used on drones and use on aircraft with a human pilot is rare.[citation needed]

Tip jet designs let the rotor push itself through the air and avoid generating torque.[11]

Engines

[edit]

The number, size and type of engine(s) used on a helicopter determines the size, function and capability of that helicopter design. The earliest helicopter engines were simple mechanical devices, such as rubber bands or spindles, which relegated the size of helicopters to toys and small models. For a half century before the first airplane flight, steam engines were used to forward the development of the understanding of helicopter aerodynamics, but the limited power did not allow for manned flight. The introduction of the internal combustion engine at the end of the 19th century became the watershed for helicopter development as engines began to be developed and produced that were powerful enough to allow for helicopters able to lift humans.[citation needed]

Early helicopter designs utilized custom-built engines or rotary engines designed for airplanes, but these were soon replaced by more powerful automobile engines and radial engines. The single, most-limiting factor of helicopter development during the first half of the 20th century was that the amount of power produced by an engine was not able to overcome the engine's weight in vertical flight. This was overcome in early successful helicopters by using the smallest engines available. When the compact, flat engine was developed, the helicopter industry found a lighter-weight powerplant easily adapted to small helicopters, although radial engines continued to be used for larger helicopters.[citation needed]

Turbine engines revolutionized the aviation industry; and the turboshaft engine for helicopter use, pioneered in December 1951 by the aforementioned Kaman K-225, finally gave helicopters an engine with a large amount of power and a low weight penalty. Turboshafts are also more reliable than piston engines, especially when producing the sustained high levels of power required by a helicopter. The turboshaft engine was able to be scaled to the size of the helicopter being designed, so that all but the lightest of helicopter models are powered by turbine engines today.[citation needed]

Special jet engines developed to drive the rotor from the rotor tips are referred to as tip jets. Tip jets powered by a remote compressor are referred to as cold tip jets, while those powered by combustion exhaust are referred to as hot tip jets. An example of a cold jet helicopter is the Sud-Ouest Djinn, and an example of the hot tip jet helicopter is the YH-32 Hornet.[citation needed]

Some radio-controlled helicopters and smaller, helicopter-type unmanned aerial vehicles, use electric motors or motorcycle engines.[12] Radio-controlled helicopters may also have piston engines that use fuels other than gasoline, such as nitromethane. Some turbine engines commonly used in helicopters can also use biodiesel instead of jet fuel.[13][14]

There are also human-powered helicopters.

Transmission

[edit]

The transmission is a mechanical system that transmits power from the engine(s) to the rotors. The transmission is a system of gears, bearings, clutches and shafts that performs several functions (1) Translates the alignment of the drive shaft to match the alignment of the rotor shafts; (2) Reduces the RPM of the drive shaft to the lower RPMs of the rotors; and (3) Enables the engine to engage or disengage from the rotors. For helicopters with tail rotors, the transmission drivetrain forks into two paths: one leading to the main rotor, and one leading to the tail rotor.[15]: 4-10 to 4-13 [16][17]

The drive shafts of helicopter engines are typically not aligned with the rotor shafts, so the transmission must translate the alignment of the drive shaft to match the shafts of the rotors. Many engine drive shafts are aligned horizontally, yet the main rotor shaft ("mast") is usually vertical, and the tail rotor shaft is often perpendicular to the engine's drive shaft. The transmission contains a series of gears, usually bevel gears, that translate the alignment of the drive shaft to the alignment of the rotor shafts.[15]: 4–12 [18]

The transmission also reduces the RPMs of the engine to the lower RPMs required by the rotors. The output drive shaft of the engine, before any gearing is applied, is typically between 3,000 and 50,000 RPM (turbine engines typically have higher RPM than piston engines). The main rotor typically rotates between 300 and 600 RPM. The tail rotor, if present, usually rotates between 1,000 and 5,000 RPM. (The RPMs of a given model of helicopter are usually fixed — the RPM ranges listed above represent a variety of helicopter models).[19] The transmission contains a series of reduction gears to reduce the engine RPM to the rotor RPMs. Several types of reduction gears may be used, including bevel gears, planetary gears, helical gears, and spur gears. Most transmissions contain several reduction gears: the engine itself may contain reduction gears (often spur gears) between the engine's internal shaft and the output drive shaft; the main rotor may have a reduction gear at its base (typically a planetary gear); and there may be reduction gears at the tail rotor, and on the shaft leading to the tail rotor.[15]: 4–11 

The transmission often includes one or more clutches, which permit the rotors to engage or disengage from the engine. A clutch is required so the engine can start up and gain speed before taking the load of the rotors. A clutch is also required in the case of engine failure: in that situation, the rotors must disengage from the engine so that the rotors can continue spinning and perform autorotation. Helicopter clutches are usually freewheel clutches relying on centrifugal forces (sprag clutchs are commonly used), but belt drive clutches are also used.[15]: 4–7, 4-12 to 4-13 

Flight controls

[edit]
Controls from a Bell 206

A helicopter has four flight control inputs. These are the cyclic, the collective, the anti-torque foot pedals, and the throttle.

The cyclic control is usually located between the pilot's legs and is commonly called the cyclic stick or just cyclic or stick and moves forwards and backwards and side to side. On most helicopters, the cyclic is similar to a joystick. However, the Robinson R22, Robinson R44 and Robinson R66 have a unique teetering-bar cyclic control system and a few helicopters have a cyclic control that descends into the cockpit from overhead.[citation needed]

The cyclic is called the cyclic because it cyclically changes the pitch of the main rotor blades. In a forward flight state, as the blades rotate, the blade rotating forward will see higher speed and a corresponding increase in lift compared to the retreating blade. As such, the angle of attack of the forward rotating blade has to be lower than the retreating blade or the helicopter will roll to the retreating blade side. This happens cyclically as the blades rotate through a complete rotation leading to the naming of this control as the cyclic. The cyclic controls this differential angle.

The cyclic controls the tilt of the rotor. In hover, the cyclic controls motion of the helicopter over the ground. In flight, the cyclic controls the pitch and roll of the helicopter.

In a hover, if the pilot pushes the cyclic forward, the rotor disk tilts forward, and the rotor produces a thrust in the forward direction. If the pilot pushes the cyclic to the side, the rotor disk tilts to that side and produces thrust in that direction, causing the helicopter to move sideways.[citation needed]

Because of precession, the cyclic moves the swashplate 90 degrees before the desired main rotor tilt. This can be seen when the rotor is stopped. With the blades aligned fore/aft, moving the cyclic forward does not change the blade angle but moving the cyclic to the side will change the blade angle.

In flight, the cyclic acts like the stick in an airplane. Moving the cyclic forward pitches the nose down for more speed. Moving the cyclic aft lifts the nose to slow the aircraft. Moving the cyclic to the side rolls the helicopter in that direction which generally leads to turning in that direction, assuming coordinated flight.

The collective pitch control or collective is located on the left side of the pilot's seat with an adjustable friction control to prevent inadvertent movement freeing the pilot's left hand for other uses. The collective changes the pitch angle of all the main rotor blades collectively (i.e. all at the same time) and independently of their rotational position. Therefore, if an up collective input is made, all the blades increase angle of attack equally, and the result is additional lift (power) to the main rotor system which can increase helicopter speed or altitude.[citation needed] Lowering the collective results in less lift from the main rotor system.

A swashplate controls the collective and cyclic pitch of the main blades. The swashplate moves up and down, along the main shaft, to change the pitch of the blades. The stick is connected to the swash plate through the collective and cyclic systems allowing both systems to independently control the angle of the blades.

The anti-torque pedals are located in the same position as the rudder pedals in a fixed-wing aircraft, and serve a similar purpose, namely to control the yaw or direction in which the nose of the aircraft is pointed. Application of the pedal in a given direction changes the pitch of the tail rotor blades, increasing or reducing the thrust produced by the tail rotor and causing the nose to yaw in the direction of the applied pedal. The pedals mechanically change the pitch of the tail rotor altering the amount of thrust produced.[citation needed] Helicopters do not exhibit adverse yaw as seen in airplanes and the pedals are not generally required when turning in forward flight. Use of the pedals is closely related to the collective in hover. For example, increasing collective increases aerodynamic drag on the main rotor system causing a yaw of the helicopter. The pedals are used to counter that yaw.

Both the cyclic and collective can have a wide variety of toggles and switches available to the pilot to control such things as aerodynamic trim, engine speed trim, radio and intercom, hook release, water release, etc. This allows the pilot to control these functions without removing their hands from the controls.

Helicopter rotors are designed to operate in a narrow range of RPM.[20][21][22][23][19] The throttle controls the power produced by the engine, which is connected to the rotor by a fixed ratio transmission. The purpose of the throttle is to maintain enough engine power to keep the rotor RPM within allowable limits so that the rotor produces enough lift for flight. The throttle control is a motorcycle-style twist grip mounted on the collective control.

Compound helicopter

[edit]
The NH-3A was experimental version of the Sea King with wings and jets.

A compound helicopter has an additional system for thrust and, typically, small stub fixed wings. This offloads the rotor in cruise, which allows its rotation to be slowed down, thus increasing the maximum speed of the aircraft. The Lockheed AH-56A Cheyenne diverted up to 90% of its engine power to a pusher propeller during forward flight.[24]

Flight

[edit]

There are three basic flight conditions for a helicopter: hover, forward flight and the transition between the two.

Hover

[edit]
An HH-65 Dolphin holding a hover while conducting rescue hoist training

Hovering is the most challenging part of flying a helicopter. Required are constant control inputs and corrections by the pilot to keep the helicopter where it is required to be.[25] Despite the complexity of the task, the control inputs in a hover are simple. The cyclic is used to eliminate drift in the horizontal plane, that is to control forward and back, right and left. The collective is used to maintain altitude. The pedals are used to control nose direction or heading. It is the interaction of these controls that makes hovering so difficult, since an adjustment in any one control requires an adjustment of the other two, creating a cycle of constant correction.[citation needed] In addition, the center of lift of the main rotor system is significantly above the center of gravity (CG) of the helicopter. Thus, any lateral perturbation of the helicopter in a hover will tend to increase as the rotor lift will increasingly roll or pitch the helicopter in a positive-feedback rotor-lift versus helicopter CG situation. The lateral motion of the helicopter lags behind the roll induced by the rotor lift side vector which will lead an inexperienced pilot into a pilot induced oscillation (PIO) and eventual loss of control.

Transition from hover to forward flight

[edit]

A hovering helicopter is surrounded by a vortex of air pushing the helicopter down. This can be a hover in ground effect or out of ground effect. Thus, when in a hover, the engine needs to provide enough power to both counter helicopter weight as well as counter this downward flow of air into the rotor system. As a helicopter moves from hover to forward flight it flies out of this downward flowing vortex and enters a state called translational lift which provides extra lift without increasing power. This state, most typically, occurs when the airspeed reaches approximately 16–24 knots (30–44 km/h; 18–28 mph), and may be necessary for a helicopter to obtain flight.[citation needed] A maneuver called a running take off involves sliding the helicopter on the ground at increasing speed until sufficient lift is achieved for flight.

Forward flight

[edit]

In forward flight a helicopter's flight controls behave more like those of a fixed-wing aircraft. Applying forward pressure on the cyclic will cause the nose to pitch down, with a resultant increase in airspeed and loss of altitude. Aft cyclic will cause the nose to pitch up, slowing the helicopter and causing it to climb. Increasing collective (power) while maintaining a constant airspeed will induce a climb while decreasing collective will cause a descent. Coordinating these two inputs, down collective plus aft cyclic or up collective plus forward cyclic, will result in airspeed changes while maintaining a constant altitude. Helicopters do not exhibit adverse yaw and the pedals are not generally needed for forward flight, even when turning.

Autorotation

[edit]

If the engine fails or is disconnected from the rotor system, the helicopter will enter an autorotation, where the helicopter's main rotor turns due to air moving up through the rotor, instead of engine power driving the rotor.

Uses

[edit]

Due to the operating characteristics of the helicopter—its ability to take off and land vertically, and to hover for extended periods of time, as well as the aircraft's handling properties under low airspeed conditions—it has proved advantageous to conduct tasks that were previously not possible with other aircraft, or were time- or work-intensive to accomplish on the ground. Today, helicopter uses include transportation of people and cargo, military uses, construction, firefighting, search and rescue, tourism, medical transport, law enforcement, agriculture, news and media, and aerial observation, among others.[26]

KPRC's Bell 206 providing aerial news coverage

A helicopter used to carry loads connected to long cables or slings is called an aerial crane. Aerial cranes are used to place heavy equipment, like radio transmission towers and large air conditioning units, on the tops of tall buildings, or when an item must be raised up in a remote area, such as a radio tower raised on the top of a hill or mountain. Helicopters are used as aerial cranes in the logging industry to lift trees out of terrain where vehicles cannot travel and where environmental concerns prohibit the building of roads.[27] These operations are referred to as longline because of the long, single sling line used to carry the load.[28] In military service helicopters are often useful for delivery of outsized slung loads that would not fit inside ordinary cargo aircraft: artillery pieces, large machinery (field radars, communications gear, electrical generators), or pallets of bulk cargo. In military operations these payloads are often delivered to remote locations made inaccessible by mountainous or riverine terrain, or naval vessels at sea.[citation needed]

Soldiers await pickup from CH-47 helicopters

In electronic news gathering, helicopters have provided aerial views of some major news stories, and have been doing so, from the late 1960s. Helicopters have also been used in films, both in front and behind the camera.[29]

The largest single non-combat helicopter operation in history was the disaster management operation following the 1986 Chernobyl nuclear disaster. Hundreds of pilots were involved in airdrop and observation missions, making dozens of sorties a day for several months.[citation needed]

"Helitack" is the use of helicopters to combat wildland fires.[30] The helicopters are used for aerial firefighting (water bombing) and may be fitted with tanks or carry helibuckets. Helibuckets, such as the Bambi bucket, are usually filled by submerging the bucket into lakes, rivers, reservoirs, or portable tanks. Tanks fitted onto helicopters are filled from a hose while the helicopter is on the ground or water is siphoned from lakes or reservoirs through a hanging snorkel as the helicopter hovers over the water source. Helitack helicopters are also used to deliver firefighters, who rappel down to inaccessible areas, and to resupply firefighters. Common firefighting helicopters include variants of the Bell 205 and the Erickson S-64 Aircrane helitanker.[citation needed]

Exercises with a helicopter to rescue someone in water

Helicopters are used as air ambulances for emergency medical assistance in situations when an ambulance cannot easily or quickly reach the scene, or cannot transport the patient to a medical facility in time. Helicopters are also used when patients need to be transported between medical facilities and air transportation is the most practical method. An air ambulance helicopter is equipped to stabilize and provide limited medical treatment to a patient while in flight. The use of helicopters as air ambulances is often referred to as "MEDEVAC", and patients are referred to as being "airlifted", or "medevaced". This use was pioneered in the Korean War, when time to reach a medical facility was reduced to three hours from the eight hours needed in World War II, and further reduced to two hours by the Vietnam War.[31] In naval service a prime function of rescue helicopters is to promptly retrieve downed aircrew involved in crashes occurring upon launch or recovery aboard aircraft carriers. In past years this function was performed by destroyers escorting the carrier, but since then helicopters have proved vastly more effective.[citation needed]

Police departments and other law enforcement agencies use helicopters to pursue suspects and patrol the skies. Since helicopters can achieve a unique aerial view, they are often used in conjunction with police on the ground to report on suspects' locations and movements. They are often mounted with lighting and heat-sensing equipment for night pursuits.

The Mil-24 'Hind' is a well-known military attack helicopter

Military forces use attack helicopters to conduct aerial attacks on ground targets. Such helicopters are mounted with missile launchers and miniguns. Transport helicopters are used to ferry troops and supplies where the lack of an airstrip would make transport via fixed-wing aircraft impossible. The use of transport helicopters to deliver troops as an attack force on an objective is referred to as "air assault". Unmanned aerial systems (UAS) helicopter systems of varying sizes are developed by companies for military reconnaissance and surveillance duties. Naval forces also use helicopters equipped with dipping sonar for anti-submarine warfare, since they can operate from small ships.[citation needed]

Oil companies charter helicopters to move workers and parts quickly to remote drilling sites located at sea or in remote locations. The speed advantage over boats makes the high operating cost of helicopters cost-effective in ensuring that oil platforms continue to operate. Various companies specialize in this type of operation.[citation needed]

NASA developed Ingenuity, a 1.8 kg (4.0 lb) helicopter used to survey Mars (along with a rover). It began service in February 2021 and was retired due to sustained rotor blade damage in January 2024 after 73 sorties. As the Martian atmosphere is 100 times thinner than Earth's, its two blades spin at close to 3,000 revolutions a minute, approximately 10 times faster than that of a terrestrial helicopter.[32]

Market

[edit]

In 2017, 926 civil helicopters were shipped for $3.68 billion, led by Airbus Helicopters with $1.87 billion for 369 rotorcraft, Leonardo Helicopters with $806 million for 102 (first three-quarters only), Bell Helicopter with $696 million for 132, then Robinson Helicopter with $161 million for 305.[33]

By October 2018, the in-service and stored helicopter fleet of 38,570 with civil or government operators was led by Robinson Helicopter with 24.7% followed by Airbus Helicopters with 24.4%, then Bell with 20.5 and Leonardo with 8.4%, Russian Helicopters with 7.7%, Sikorsky Aircraft with 7.2%, MD Helicopters with 3.4% and other with 2.2%. The most widespread model is the piston Robinson R44 with 5,600, then the H125/AS350 with 3,600 units, followed by the Bell 206 with 3,400. Most were in North America with 34.3% then in Europe with 28.0% followed by Asia-Pacific with 18.6%, Latin America with 11.6%, Africa with 5.3% and Middle East with 1.7%.[34]

History

[edit]

Early design

[edit]
Leonardo's "aerial screw"

The earliest references for vertical flight came from China. Since around 400 BC,[35] Chinese children have played with bamboo flying toys (or Chinese top).[36][37][38] This bamboo-copter is spun by rolling a stick attached to a rotor. The spinning creates lift, and the toy flies when released.[35] The 4th-century AD Daoist book Baopuzi by Ge Hong (抱朴子 "Master who Embraces Simplicity") reportedly describes some of the ideas inherent to rotary wing aircraft.[39]

Designs similar to the Chinese helicopter toy appeared in some Renaissance paintings and other works.[40] In the 18th and early 19th centuries Western scientists developed flying machines based on the Chinese toy.[41]

It was not until the early 1480s, when Italian polymath Leonardo da Vinci created a design for a machine that could be described as an "aerial screw", that any recorded advancement was made towards vertical flight. His notes suggested that he built small flying models, but there were no indications for any provision to stop the rotor from making the craft rotate.[42][43] As scientific knowledge increased and became more accepted, people continued to pursue the idea of vertical flight.[citation needed]

In July 1754, Russian Mikhail Lomonosov had developed a small coaxial modeled after the Chinese top but powered by a wound-up spring device[41] and demonstrated it to the Russian Academy of Sciences. It was powered by a spring, and was suggested as a method to lift meteorological instruments. In 1783, Christian de Launoy, and his mechanic, Bienvenu, used a coaxial version of the Chinese top in a model consisting of contrarotating turkey flight feathers[41] as rotor blades, and in 1784, demonstrated it to the French Academy of Sciences. Sir George Cayley, influenced by a childhood fascination with the Chinese flying top, developed a model of feathers, similar to that of Launoy and Bienvenu, but powered by rubber bands. By the end of the century, he had progressed to using sheets of tin for rotor blades and springs for power. His writings on his experiments and models would become influential on future aviation pioneers.[42] Alphonse Pénaud would later develop coaxial rotor model helicopter toys in 1870, also powered by rubber bands. One of these toys, given as a gift by their father, would inspire the Wright brothers to pursue the dream of flight.[44]

Experimental helicopter by Enrico Forlanini (1877), exposed at the Museo nazionale della scienza e della tecnologia Leonardo da Vinci of Milan, Italy

In 1861, the word "helicopter" was coined by Gustave de Ponton d'Amécourt, a French inventor who demonstrated a small steam-powered model. While celebrated as an innovative use of a new metal, aluminum, the model never lifted off the ground. D'Amecourt's linguistic contribution would survive to eventually describe the vertical flight he had envisioned. Steam power was popular with other inventors as well. In 1877, the Italian engineer, inventor and aeronautical pioneer Enrico Forlanini developed an unmanned helicopter powered by a steam engine. It rose to a height of 13 meters (43 feet), where it remained for 20 seconds, after a vertical take-off from a park in Milan.[45] Milan has dedicated its city airport to Enrico Forlanini, also named Linate Airport,[46] as well as the nearby park, the Parco Forlanini.[47] Emmanuel Dieuaide's steam-powered design featured counter-rotating rotors powered through a hose from a boiler on the ground.[42] In 1887 Parisian inventor, Gustave Trouvé, built and flew a tethered electric model helicopter.[citation needed]

In July 1901, the maiden flight of Hermann Ganswindt's helicopter took place in Berlin-Schöneberg; this was probably the first heavier-than-air motor-driven flight carrying humans. A movie covering the event was taken by Max Skladanowsky, but it remains lost.[48]

In 1885, Thomas Edison was given US$1,000 (equivalent to $35,000 today) by James Gordon Bennett, Jr., to conduct experiments towards developing flight. Edison built a helicopter and used the paper for a stock ticker to create guncotton, with which he attempted to power an internal combustion engine. The helicopter was damaged by explosions and one of his workers was badly burned. Edison reported that it would take a motor with a ratio of three to four pounds per horsepower produced to be successful, based on his experiments.[49] Ján Bahýľ, a Slovak inventor, adapted the internal combustion engine to power his helicopter model that reached a height of 0.5 meters (1.6 feet) in 1901. On 5 May 1905, his helicopter reached 4 meters (13 feet) in altitude and flew for over 1,500 meters (4,900 feet).[50] In 1908, Edison patented his own design for a helicopter powered by a gasoline engine with box kites attached to a mast by cables for a rotor,[51] but it never flew.[52]

First flights

[edit]

In 1906, two French brothers, Jacques and Louis Breguet, began experimenting with airfoils for helicopters. In 1907, those experiments resulted in the Gyroplane No.1, possibly as the earliest known example of a quadcopter. Although there is some uncertainty about the date, sometime between 14 August and 29 September 1907, the Gyroplane No. 1 lifted its pilot into the air about 0.6 metres (2 ft) for a minute.[53][54] The Gyroplane No. 1 proved to be extremely unsteady and required a man at each corner of the airframe to hold it steady. For this reason, the flights of the Gyroplane No. 1 are considered to be the first manned flight of a helicopter, but not a free or untethered flight.[citation needed]

Paul Cornu's helicopter, 1907

That same year, fellow French inventor Paul Cornu designed and built the Cornu helicopter which used two 6.1-metre (20 ft) counter-rotating rotors driven by a 24 hp (18 kW) Antoinette engine. On 13 November 1907, it lifted its inventor to 0.3 metres (1 ft) and remained aloft for 20 seconds. Even though this flight did not surpass the flight of the Gyroplane No. 1, it was reported to be the first truly free flight with a pilot.[n 1] Cornu's helicopter completed a few more flights and achieved a height of nearly 2.0 metres (6.5 ft), but it proved to be unstable and was abandoned.[53]

In 1909, J. Newton Williams of Derby, Connecticut, and Emile Berliner of Washington, D.C., flew a helicopter "on three occasions" at Berliner's lab in Washington's Brightwood neighborhood.[55]

In 1911, Slovenian philosopher and economist Ivan Slokar patented a helicopter configuration.[56][57][58]

The Danish inventor Jacob Ellehammer built the Ellehammer helicopter in 1912. It consisted of a frame equipped with two counter-rotating discs, each of which was fitted with six vanes around its circumference. After indoor tests, the aircraft was demonstrated outdoors and made several free take-offs. Experiments with the helicopter continued until September 1916, when it tipped over during take-off, destroying its rotors.[59]

During World War I, Austria-Hungary developed the PKZ, an experimental helicopter prototype, with two aircraft built.[citation needed]

Early development

[edit]

In the early 1920s, Argentine Raúl Pateras-Pescara de Castelluccio, while working in Europe, demonstrated one of the first successful applications of cyclic pitch.[53] Coaxial, contra-rotating, biplane rotors could be warped to cyclically increase and decrease the lift they produced. The rotor hub could also be tilted forward a few degrees, allowing the aircraft to move forward without a separate propeller to push or pull it. Pateras-Pescara was also able to demonstrate the principle of autorotation. By January 1924, Pescara's helicopter No. 1 was tested but was found to be underpowered and could not lift its own weight. His 2F fared better and set a record.[60] The British government funded further research by Pescara which resulted in helicopter No. 3, powered by a 250-horsepower (190 kW) radial engine which could fly for up to ten minutes.[61][62]

In March 1923 Time magazine reported Thomas Edison sent George de Bothezat a congratulations for a successful helicopter test flight. Edison wrote, "So far as I know, you have produced the first successful helicopter." The helicopter was tested at McCook's Field and remained airborne for 2 minutes and 45 seconds at a height of 15 feet.[63]

On 14 April 1924, Frenchman Étienne Oehmichen set the first helicopter world record recognized by the Fédération Aéronautique Internationale (FAI), flying his quadrotor helicopter 360 meters (1,180 ft).[64] On 18 April 1924, Pescara beat Oemichen's record, flying for a distance of 736 meters (2,415 ft)[60] (nearly 0.80 kilometers or .5 miles) in 4 minutes and 11 seconds (about 13 km/h or 8 mph), maintaining a height of 1.8 meters (6 feet).[65] On 4 May, Oehmichen completed the first one-kilometer (0.62 mi) closed-circuit helicopter flight in 7 minutes 40 seconds with his No. 2 machine.[53][66]

In the US, George de Bothezat built the quadrotor helicopter de Bothezat helicopter for the United States Army Air Service but the Army cancelled the program in 1924, and the aircraft was scrapped.[citation needed]

Albert Gillis von Baumhauer, a Dutch aeronautical engineer, began studying rotorcraft design in 1923. His first prototype "flew" ("hopped" and hovered in reality) on 24 September 1925,[67] with Dutch Army-Air arm Captain Floris Albert van Heijst at the controls. The controls that van Heijst used were von Baumhauer's inventions, the cyclic and collective.[68][69] Patents were granted to von Baumhauer for his cyclic and collective controls by the British ministry of aviation on 31 January 1927, under patent number 265,272.[citation needed]

In 1927,[70] Engelbert Zaschka from Germany built a helicopter, equipped with two rotors, in which a gyroscope was used to increase stability and serves as an energy accumulator for a gliding flight to make a landing. Zaschka's aircraft, the first helicopter, which ever worked so successfully in miniature, not only rises and descends vertically, but is able to remain stationary at any height.[71][72]

In 1928, Hungarian aviation engineer Oszkár Asbóth constructed a helicopter prototype that took off and landed at least 182 times, with a maximum single flight duration of 53 minutes.[73][74]

In 1930, the Italian engineer Corradino D'Ascanio built his D'AT3, a coaxial helicopter. His relatively large machine had two, two-bladed, counter-rotating rotors. Control was achieved by using auxiliary wings or servo-tabs on the trailing edges of the blades,[75] a concept that was later adopted by other helicopter designers, including Bleeker and Kaman. Three small propellers mounted to the airframe were used for additional pitch, roll, and yaw control. The D'AT3 held modest FAI speed and altitude records for the time, including altitude (18 m or 59 ft), duration (8 minutes 45 seconds) and distance flown (1,078 m or 3,540 ft).[75][76]

First practical rotorcraft

[edit]
A Cierva autogyro in the 1920s, one of the predecessors to helicopters

Spanish aeronautical engineer and pilot Juan de la Cierva invented the autogyro in the early 1920s, becoming the first practical rotorcraft.[77] In 1928, de la Cierva successfully flew an autogyro across the English Channel, from London to Paris.[78] In 1934, an autogyro became the first rotorcraft to successfully take off and land on the deck of a ship.[79] That same year, the autogyro was employed by the Spanish military during the Asturias revolt, becoming the first military deployment of a rotocraft. Autogyros were also employed in New Jersey and Pennsylvania for delivering mail and newspapers prior to the invention of the helicopter.[80] Though lacking true vertical flight capability, work on the autogyro forms the basis for helicopter analysis.[81]

Single lift-rotor success

[edit]

In the Soviet Union, Boris N. Yuriev and Alexei M. Cheremukhin, two aeronautical engineers working at the Tsentralniy Aerogidrodinamicheskiy Institut (TsAGI or the Central Aerohydrodynamic Institute), constructed and flew the TsAGI 1-EA single lift-rotor helicopter, which used an open tubing framework, a four-blade main lift rotor, and twin sets of 1.8-meter (5.9-foot) diameter, two-bladed anti-torque rotors: one set of two at the nose and one set of two at the tail. Powered by two M-2 powerplants, up-rated copies of the Gnome Monosoupape 9 Type B-2 100 CV output rotary engine of World War I, the TsAGI 1-EA made several low altitude flights.[82] By 14 August 1932, Cheremukhin managed to get the 1-EA up to an unofficial altitude of 605 meters (1,985 feet), shattering d'Ascanio's earlier achievement. As the Soviet Union was not yet a member of the FAI, however, Cheremukhin's record remained unrecognized.[83]

Nicolas Florine, a Russian engineer, built the first twin tandem rotor machine to perform a free flight. It flew in Sint-Genesius-Rode, at the Laboratoire Aérotechnique de Belgique (now von Karman Institute) in April 1933, and attained an altitude of six meters (20 feet) and an endurance of eight minutes. Florine chose a co-rotating configuration because the gyroscopic stability of the rotors would not cancel. Therefore, the rotors had to be tilted slightly in opposite directions to counter torque. Using hingeless rotors and co-rotation also minimised the stress on the hull. At the time, it was one of the most stable helicopters in existence.[84]

The Bréguet-Dorand Gyroplane Laboratoire was built in 1933. It was a coaxial helicopter, contra-rotating. After many ground tests and an accident, it first took flight on 26 June 1935. Within a short time, the aircraft was setting records with pilot Maurice Claisse at the controls. On 14 December 1935, he set a record for closed-circuit flight with a 500-meter (1,600-foot) diameter.[85] The next year, on 26 September 1936, Claisse set a height record of 158 meters (518 feet).[86] And, finally, on 24 November 1936, he set a flight duration record of one hour, two minutes and 50 seconds[87] over a 44 kilometers (27 miles) closed circuit at 44.7 kilometres per hour (27.8 mph). The aircraft was destroyed in 1943 by an Allied airstrike at Villacoublay airport.[88]

American single-rotor beginnings

[edit]

American inventor Arthur M. Young started work on model helicopters in 1928 using converted electric hover motors to drive the rotor head. Young invented the stabilizer bar and patented it shortly after. A mutual friend introduced Young to Lawrence Dale, who once seeing his work asked him to join the Bell Aircraft company. When Young arrived at Bell in 1941, he signed his patent over and began work on the helicopter. His budget was US$250,000 (equivalent to $5.3 million today) to build two working helicopters. In just six months they completed the first Bell Model 1, which spawned the Bell Model 30, later succeeded by the Bell 47.[89]

Birth of an industry

[edit]
Focke-Wulf Fw 61, the first successful helicopter

Heinrich Focke at Focke-Wulf had purchased a license from Cierva Autogiro Company, which according to Frank Kingston Smith Sr., included "the fully controllable cyclic/collective pitch hub system". In return, Cierva Autogiro received a cross-license to build the Focke-Achgelis helicopters. Focke designed the world's first practical helicopter, the transverse twin-rotor Focke-Wulf Fw 61, which first flew in June 1936. It was demonstrated by Hanna Reitsch in February 1938 inside the Deutschlandhalle in Berlin.[90] The Fw 61 set a number of FAI records from 1937 to 1939, including: maximum altitude of 3,427 metres (11,243 ft), maximum distance of 230 kilometres (140 mi), and maximum speed of 124 kilometres per hour (77 mph).[91] Autogiro development was now being bypassed by a focus on helicopters.[92]

During World War II, Nazi Germany used helicopters in small numbers for observation, transport, and medical evacuation. The Flettner Fl 282 Kolibri synchropter—using the same basic configuration as Anton Flettner's own pioneering Fl 265—was used in the Baltic, Mediterranean, and Aegean Seas.[93] The Focke-Achgelis Fa 223 Drache, like the Fw 61, used two transverse rotors, and was the largest rotorcraft of the war.[94] Extensive bombing by the Allied forces prevented Germany from producing helicopters in large quantities during the war.

The Sikorsky R-4 became the first mass-produced helicopter in the early 1940s, and was capable of vertical takeoff. It performed the first medevac flights during WW2.

In the United States, Russian-born engineer Igor Sikorsky and Wynn Laurence LePage competed to produce the U.S. military's first helicopter. LePage received the patent rights to develop helicopters patterned after the Fw 61, and built the XR-1[95] in 1941. Meanwhile, Sikorsky settled on a simpler, single-rotor design, the VS-300 of 1939, which turned out to be the first practical single lifting-rotor helicopter design. After experimenting with configurations to counteract the torque produced by the single main rotor, Sikorsky settled on a single, smaller rotor mounted on the tail boom.[citation needed]

Developed from the VS-300, Sikorsky's R-4 of 1942 was the first large-scale mass-produced helicopter, with a production order for 100 aircraft. The R-4 was the only Allied helicopter to serve in World War II, used primarily for search and rescue (by the USAAF 1st Air Commando Group) in the Burma campaign;[96] in Alaska; and in other areas with harsh terrain. Total production reached 131 helicopters before the R-4 was replaced by other Sikorsky helicopters such as the R-5 and the R-6. In all, Sikorsky produced over 400 helicopters before the end of World War II.[97]

While LePage and Sikorsky built their helicopters for the military, Bell Aircraft hired Arthur Young to help build a helicopter using Young's two-blade teetering rotor design, which used a weighted stabilizer bar placed at a 90° angle to the rotor blades. The subsequent Model 30 helicopter of 1943 showed the design's simplicity and ease of use. The Model 30 was developed into the Bell 47 of 1945, which became the first helicopter certified for civilian use in the United States (March 1946). Produced in several countries, the Bell 47 was the most popular helicopter model for nearly 30 years.[citation needed]

Turbine age

[edit]

In 1951, at the urging of his contacts at the Department of the Navy, Charles Kaman modified his K-225 synchropter—a design for a twin-rotor helicopter concept first pioneered by Anton Flettner in 1939, with the aforementioned Fl 265 piston-engined design in Germany—with a new kind of engine, the turboshaft engine. This adaptation of the turbine engine provided a large amount of power to Kaman's helicopter with a lower weight penalty than piston engines, with their heavy engine blocks and auxiliary components. On 11 December 1951, the Kaman K-225 became the first turbine-powered helicopter in the world. Two years later, on 26 March 1954, a modified Navy HTK-1, another Kaman helicopter, became the first twin-turbine helicopter to fly.[98] However, it was the Sud Aviation Alouette II that would become the first helicopter to be produced with a turbine-engine.[99]

Reliable helicopters capable of stable hover flight were developed decades after fixed-wing aircraft. This is largely due to higher engine power density requirements than fixed-wing aircraft. Improvements in fuels and engines during the first half of the 20th century were a critical factor in helicopter development. The availability of lightweight turboshaft engines in the second half of the 20th century led to the development of larger, faster, and higher-performance helicopters. While smaller and less expensive helicopters still use piston engines, turboshaft engines are the preferred powerplant for helicopters today.[citation needed]

Safety

[edit]

Maximum speed limit

[edit]
A Russian Air Force Kamov Ka-50 using a coaxial rotor system

There are several reasons a helicopter cannot fly as fast as a fixed-wing aircraft. When the helicopter is hovering, the outer tips of the rotor travel at a speed determined by the length of the blade and the rotational speed. In a moving helicopter, however, the speed of the blades relative to the air depends on the speed of the helicopter as well as on their rotational speed. The airspeed of the advancing rotor blade is much higher than that of the helicopter itself. It is possible for this blade to exceed the speed of sound, and thus produce vastly increased drag and vibration.[citation needed]

At the same time, the advancing blade creates more lift traveling forward, the retreating blade produces less lift. If the aircraft were to accelerate to the air speed that the blade tips are spinning, the retreating blade passes through air moving at the same speed of the blade and produces no lift at all, resulting in very high torque stresses on the central shaft that can tip down the retreating-blade side of the vehicle, and cause a loss of control. Dual counter-rotating blades prevent this situation due to having two advancing and two retreating blades with balanced forces.[citation needed]

The Lynx helicopter is noted for its speed

Because the advancing blade has higher airspeed than the retreating blade and generates a dissymmetry of lift, rotor blades are designed to "flap" – lift and twist in such a way that the advancing blade flaps up and develops a smaller angle of attack. Conversely, the retreating blade flaps down, develops a higher angle of attack, and generates more lift. At high speeds, the force on the rotors is such that they "flap" excessively, and the retreating blade can reach too high an angle and stall. For this reason, the maximum safe forward airspeed of a helicopter is given a design rating called VNE, velocity, never exceed.[100] In addition, it is possible for the helicopter to fly at an airspeed where an excessive amount of the retreating blade stalls, which results in high vibration, pitch-up, and roll into the retreating blade.[citation needed]

Noise

[edit]

At the end of the 20th century, designers began working on helicopter noise reduction. Urban communities have often expressed great dislike of noisy aviation or noisy aircraft, and police and passenger helicopters can be unpopular because of the sound. The redesigns followed the closure of some city heliports and government action to constrain flight paths in national parks and other places of natural beauty.[citation needed]

Vibration

[edit]
NASA experiment for piezoelectric rotor blades to potentially reduce the noise and vibration

To reduce vibration, all helicopters have rotor adjustments for height and weight. A maladjusted helicopter can easily vibrate so much that it will shake itself apart. Blade height is adjusted by changing the pitch of the blade. Weight is adjusted by adding or removing weights on the rotor head and/or at the blade end caps. Most also have vibration dampers for height and pitch. Some also use mechanical feedback systems to sense and counter vibration. Usually the feedback system uses a mass as a "stable reference" and a linkage from the mass operates a flap to adjust the rotor's angle of attack to counter the vibration. Adjustment can be difficult in part because measurement of the vibration is hard, usually requiring sophisticated accelerometers mounted throughout the airframe and gearboxes. The most common blade vibration adjustment measurement system is to use a stroboscopic flash lamp, and observe painted markings or coloured reflectors on the underside of the rotor blades. The traditional low-tech system is to mount coloured chalk on the rotor tips, and see how they mark a linen sheet. Health and Usage Monitoring Systems (HUMS) provide vibration monitoring and rotor track and balance solutions to limit vibration.[101] Gearbox vibration most often requires a gearbox overhaul or replacement. Gearbox or drive train vibrations can be extremely harmful to a pilot. The most severe effects are pain, numbness, and loss of tactile discrimination or dexterity.[citation needed]

Loss of tail-rotor effectiveness

[edit]

For a standard helicopter with a single main rotor, the tips of the main rotor blades produce a vortex ring in the air, which is a spiraling and circularly rotating airflow. As the craft moves forward, these vortices trail off behind the craft.[citation needed]

When hovering with a forward diagonal crosswind, or moving in a forward diagonal direction, the spinning vortices trailing off the main rotor blades will align with the rotation of the tail rotor and cause an instability in flight control.[102]

When the trailing vortices colliding with the tail rotor are rotating in the same direction, this causes a loss of thrust from the tail rotor. When the trailing vortices rotate in the opposite direction of the tail rotor, thrust is increased. Use of the foot pedals is required to adjust the tail rotor's angle of attack, to compensate for these instabilities.[citation needed]

These issues are due to the exposed tail rotor cutting through open air around the rear of the vehicle. This issue disappears when the tail is instead ducted, using an internal impeller enclosed in the tail and a jet of high pressure air sideways out of the tail, as the main rotor vortices can not impact the operation of an internal impeller.[citation needed]

Critical wind azimuth

[edit]

For a standard helicopter with a single main rotor, maintaining steady flight with a crosswind presents an additional flight control problem, where strong crosswinds from certain angles will increase or decrease lift from the main rotors. This effect is also triggered in a no-wind condition when moving the craft diagonally in various directions, depending on the direction of main rotor rotation.[103]

This can lead to a loss of control and a crash or hard landing when operating at low altitudes, due to the sudden unexpected loss of lift, and insufficient time and distance available to recover.[citation needed]

Transmission

[edit]

Conventional rotary-wing aircraft use a set of complex mechanical gearboxes to convert the high rotation speed of gas turbines into the low speed required to drive main and tail rotors. Unlike powerplants, mechanical gearboxes cannot be duplicated (for redundancy) and have always been a major weak point in helicopter reliability. In-flight catastrophic gear failures often result in gearbox jamming and subsequent fatalities, whereas loss of lubrication can trigger onboard fire.[citation needed] Another weakness of mechanical gearboxes is their transient power limitation, due to structural fatigue limits. Recent EASA studies point to engines and transmissions as prime cause of crashes just after pilot errors.[104]

By contrast, electromagnetic transmissions do not use any parts in contact; hence lubrication can be drastically simplified, or eliminated. Their inherent redundancy offers good resilience to single point of failure. The absence of gears enables high power transient without impact on service life. The concept of electric propulsion applied to helicopter and electromagnetic drive was brought to reality by Pascal Chretien who designed, built and flew world's first man-carrying, free-flying electric helicopter. The concept was taken from the conceptual computer-aided design model on 10 September 2010 to the first testing at 30% power on 1 March 2011 – less than six months. The aircraft first flew on 12 August 2011. All development was conducted in Venelles, France.[105][106]

In addition to regulatory measures, helicopter operators are also supported by voluntary safety teams that analyze accident data and promote specific countermeasures. In the United States, for example, the U.S. Helicopter Safety Team (USHST) publishes accident reviews and safety enhancements that address issues such as loss of control in flight, inadvertent flight into instrument meteorological conditions (IIMC), and low-altitude operations, encouraging improvements in training, operational decision-making, and the use of safety-enhancing technologies.[107][108]

Hazards

[edit]
A Eurocopter AS350, destroyed after its main rotor struck the side of a mountain while at low altitude

As with any moving vehicle, unsafe operation could result in loss of control, structural damage, or loss of life. The following is a list of some of the potential hazards for helicopters:

  • Settling with power is when the aircraft has insufficient power to arrest its descent. This hazard can develop into vortex ring state if not corrected early.[109]
  • Vortex ring state is a hazard induced by a combination of low airspeed, high power setting, and high descent rate. Rotor-tip vortices circulate from the high pressure air below the rotor disk to low pressure air above the disk, so that the helicopter settles into its own descending airflow.[109] Adding more power increases the rate of air circulation and aggravates the situation. It is sometimes confused with settling with power, but they are aerodynamically different.
  • Retreating blade stall is experienced during high speed flight and is the most common limiting factor of a helicopter's forward speed.
  • Ground resonance is a self-reinforcing vibration that occurs when the lead/lag spacing of the blades of an articulated rotor system becomes irregular.
  • Low-G condition is an abrupt change from a positive G-force state to a negative G-force state that results in loss of lift (unloaded disc) and subsequent roll over. If aft cyclic is applied while the disc is unloaded, the main rotor could strike the tail causing catastrophic failure.[110]
  • Dynamic rollover in which the helicopter pivots around one of the skids and 'pulls' itself onto its side (almost like a fixed-wing aircraft ground loop).
  • Powertrain failures, especially those that occur within the shaded area of the height–velocity diagram.
  • Tail rotor failures which occur from either a mechanical malfunction of the tail rotor control system or a loss of tail rotor thrust authority, called "loss of tail-rotor effectiveness" (LTE).
  • Brownout in dusty conditions or whiteout in snowy conditions.
  • Low rotor RPM, is when the engine cannot drive the blades at sufficient RPM to maintain flight.
  • Rotor overspeed, which can over-stress the rotor hub pitch bearings (brinelling) and, if severe enough, cause blade separation from the aircraft.
  • Wire and tree strikes due to low altitude operations and take-offs and landings in remote locations.[111]
  • Controlled flight into terrain in which the aircraft is flown into the ground unintentionally due to a lack of situational awareness.
  • Mast bumping in some helicopters[112]

Reviews for Helicopter Ride and Tours Dubai


Cristina Farrugia

We booked this as a surprise for my son's birthday and we nailed it - he loved the thrill of the helicopter ride itself, but also the spectacular views from above. The pilot was very friendly and knowledgeable. We learned so much more about Abu Dhabi than we would have ever done from walking around - and the views from above of the Mosque and of the palaces are unmatched.It is MUST experience in Abu Dhabi.

I recently had the pleasure of taking a helicopter ride with your company, and I wanted to take a moment to share my experience. From start to finish, everything was exceptionally well-organized. The views during the ride were absolutely breathtaking, and the pilot's professionalism and knowledge added so much to the overall experience. It was clear that safety was a top priority, which made me feel comfortable and secure throughout the flight. The only suggestion I have for improvement would be [less timing of the ride] However, this did not detract from what was an otherwise fantastic experience. Overall, I thoroughly enjoyed the ride, and I would highly recommend it to others. Thank you for providing such a memorable experience!
