Helicopter Aircraft. The Eurocopter AS332 Super Puma is a four-bladed, twin-engine, medium-size utility helicopter marketed for both civil and military use. Originally designed and built by Aérospatiale, it is an enlarged and re-engined version of the original Aérospatiale Puma. The Super Puma first flew on 13 September 1978. In 1974, Aérospatiale commenced development of a new medium transport helicopter based on its SA 330 Puma, announcing the project at the 1975 Paris Air Show. While the new design was of similar layout to the AS 330, it was powered by two of the new and more powerful Turbomeca Makila turboshaft engines powering a four-bladed composite main rotor, and was designed to be withstand damage better, with a more robust fuselage structure, a new crashworthy undercarriage and the ability to withstand battle damage to the rotor blades and other key mechanical systems.

It was fitted with a ventral fin under the tail a more streamlined nose compared with the SA 330, while from the start was planned to be available with two fuselage lengths, with a short fuselage version offering similar capacity to the SA 330, which gives better performance in "hot and high" conditions and a stretched version allowing more passengers to be carried when weight is less critical. A pre-production prototype, the SA 331, modified from a SA 330 airframe with Makila engines and a new gearbox, flew on 5 September 1977. The first prototype of the full Super Puma made its maiden flight on 13 September 1978, being followed by a further five prototypes. The type has proved immensely successful, chosen by 37 military forces around the world, and some 1,000 civil operators. The Super Puma has proved especially well-suited to the North Sea oil industry, where it is used to ferry personnel and equipment to and from oil platforms. In civilian configuration it can seat approximately 18 passengers and two crew, though since the early 2000s most oil companies have banned use of the middle-rear seat reducing effective capacity to 17+2. This down-rating is due to difficulties encountered in evacuating through the rear-most windows in crashes at sea. A wide variety of specialised military variants are in use, including dedicated Search and rescue (SAR) and Anti-submarine warfare (ASW) versions. Since 1990, military Super Pumas have been marketed as the AS532 Cougar. AS332 Super Puma (wallpaper 1). AS332 Super Puma helicopter aircraft images wallpaper gallery 1.

Helicopter Aircraft. The Sikorsky X2 is an experimental compound helicopter with coaxial rotors under development by the American aircraft manufacture Sikorsky Aircraft. Sikorsky’s futuristic X2 high-speed helicopter technology demonstrator made its first flight today in Horseheads, N.Y., in the hands of chief test pilot Kevin L. Bredenbeck. The single-engined fly-by-wire aircraft features coaxial rotors and a pusher propeller that Sikorsky believes will revolutionize the helicopter world with cruise speeds of up to 250 kts, some 100 kts faster than current production helicopters. “This isn’t an airplane we are training to hover. It’s a helicopter that will go very, very fast,” said Sikorsky CEO Jeff Pino. “I think it will get to 260 kts.” (The helicopter world speed record is held by a Westland Lynx at 216.45 kts). Today’s flight lasted 30 minutes, during which Bredenbeck demonstrated hover, forward flight, and a hover turn. Current helicopter speeds are limited by rotor aerodynamics. Sikorsky X2 (wallpaper 1). Sikorsky X2 Helicopter images wallpaper gallery 1. Sikorsky X2 airplane pictures and images collection 1. In contrast the X2’s coaxial rotor system is optimized for all regimes of flight by a fly-by-wire control system that will slow the rotors at high forward speeds to prevent their tips going supersonic, while maximizing lift and minimizing drag by adjusting the pitch of the rigid, carbon-fiber blades. The counter-rotating rotors provide equal lift on each side of the aircraft and, unlike a traditional helicopter, are relieved of having to provide all the forward propulsion by a large pusher propeller at the rear of the fuselage. The rigidity of the blades allows the rotors to be closely spaced only two feet apart, further reducing drag. Sikorsky believes the gap can be reduced even more in the future. The X2 technology demonstrator is powered by a 1,452 shp, FADEC-equipped T800 turboshaft engine that was previously installed in one of the Comanche helicopter prototypes. It drives both the rotor and the pusher propeller through two gearboxes. So far the aerospace industry’s solution to high speed, vertical flight has been the hugely complex tiltrotor, a hybrid airplane with rotors. The X2 differs markedly in that it is still a helicopter that can go fast, autorotate, hover, and fly nap of the earth. The X2 can match the speed of the Bell/Agusta BA609 tiltrotor with far less complexity, according to Steve Estill, Sikorsky’s vice president for worldwide sales. X2 technology is especially well suited to missions such as flying fast to oil rigs, which would call for development of a light to intermediate X2 twin of the same size as the 12-passenger S-76 or 19-passenger S-92.

Helicopter Aircraft. The MH-6 Little Bird, also known as "The Killer Egg" and its attack variant, the AH-6, are single-engine light helicopters used for special operations aviation in the United States Army. Originally based on a modified OH-6A, it was later based on the MD 500E, with a single five-bladed main rotor. The newest version, the MH-6M, is based on the MD 530F and has a single, six-bladed main rotor and four-bladed tail rotor. The A/MH-6 was started in 1960, the U.S. Army issued Technical Specification 153 for a Light Observation Helicopter (LOH) that could perform personnel transport, escort and attack missions, casualty evacuation and observation. Twelve companies took part in the competition and Hughes Tool Company's Aircraft Division submitted the Model 369. Two designs, those submitted by Fairchild-Hiller and Bell, were selected as finalists by the Army-Navy design competition board, but the Army later included the helicopter from Hughes as well. The Boeing (McDonnell Dougles) (formerly Hughes model 369) OH-6A, was designed for use as a military scout during the Vietnam war to meet the U.S. Army's need for an extremely maneuverable light observation helicopter (LOH program). The Hughes OH-6A Cayuse was quite effective when teamed with the AH-1G Cobra attack helicopter as part of what were known as "Pink Teams". AH-6 Little Bird (wallpaper 1). AH-6 Little Bird aircraft images wallpaper gallery 1. AH-6 Little Bird airplane pictures and images collection 1. The OH-6A "Loach" would find targets by flying low, "trolling" for fire, and lead in a Cobra, or "Snake", to attack. The OH-6A could be armed with the M27 armament subsystem, the M134 six-barrel 7.62mm "minigun" or the M129 40mm grenade launcher on the XM8 armament subsystem. Two special operations versions of the OH-6A are the "Little Bird" AH-6C armed variant, and the MH-6B transport/utility version, which can carry up to six personnel for quick insertion and extraction missions. A previous version, the EH-6B, was used for command, control and radio relay. The MH-6 Little Bird is the only light assault helicopter in the Army inventory. It provides assault helicopter support to special operations forces and can be armed with a combination of guns and folding fin aerial rockets. It has an unrefueled range of 250 nautical miles. The AH-6 Little Bird Gun, a light attack helicopter, has been tested and proven in combat. Armed with guns, Hellfire missiles, and 2.75-inch FFAR, it provides armed helicopter support to both ground and air special operations. The unrefueled range of the AH-6 is 250 nautical miles. These versions were all powered by a single Allison T-63 252 SHP engine. Later versions are based on the successful Boeing (McDonnell Douglas) MD-500/MD-530 series helicopters. The latest versions of these aircraft, the AH-6J attack helicopter and MH-6J insertion and extraction transport, based on the MD-530F, feature a more powerful engine and improved avionics, including an embedded GPS/inertial navigation system and forward-looking infrared (FLIR). The AH-6J can be armed with two seven-tube 2.75 inch rocket launchers and two 7.62mm M134 "miniguns". The "Little Bird" can also be armed with .50 Cal. machine guns, MK19 40mm grenade machine gun, Hellfire missiles, and Air-to-Air Stinger (ATAS) missiles. AH-6 Little Bird (wallpaper 1).

Helicopter Aircraft. The Mil Mi-28 (NATO reporting name 'Havoc') is a Russian all-weather day-night military tandem two-seat anti-armour attack helicopter. It is a dedicated attack helicopter with no intended secondary transport capability, better optimized than the Mil Mi-24 for the role. It carries a single gun in an undernose barbette, plus external loads carried on pylons beneath stub wings. In 1972, following completion of the Mi-24, development began on a unique attack helicopter with transport capability. The new design had a reduced transport capability (3 troops instead of 8), omitted the cabin, to provide better overall performance and higher top speed. Improved performance was important for its intended role fighting against tanks and enemy helicopters and covering helicopter landing operations. Initially, many different designs were considered, including an unconventional project with two main rotors, placed with engines on tips of wings (in perpendicular layout), and with an additional pusher propeller on the tail. Mi-28 Havoc (wallpaper 1). Mi-28 Havoc aircraft images wallpaper gallery 1. Mi-28 Havoc airplane pictures and images collection 1. In 1977, a preliminary design was chosen, in a classic single-rotor layout. It lost its similarity to the Mi-24, and even the canopies were smaller, with flat surfaces. The Mi-28 Havoc is a new-generation attack helicopter that functions as an air-to-air and air-to-ground partner for the Mi-24 Hind and Ka-50 Hokum. The five-blade main rotor is mounted above the body midsection, and short, wide, tapered, weapon-carrying wings are mounted to the rear of body midsection. Two turboshaft engines in pods are mounted alongside the top of the fuselage with downturned exhausts. The fuselage is slender and tapers to the tail boom and nose. It features a tandem, stepped-up cockpits and a cannon mounted beneath the belly, with fixed landing gear. The tapering tail boom with a swept-back fin has a flat high-mounted on the fin and a rotor mounted on right. The Mi-28N and Kamov Ka-50 are competing to fulfil the Russian Army Aviation requirement for a night-capable anti-tank helicopter, a replacement to the Mi-24 created 25 years ago. The Mi-28N is based on the Mi-28A, a daylight helicopter first flown in December 1982. In comparison with the AH-64D Longbow Apache, the 10,5-ton Mi-28N is some 2.5 tons heavier, partly due to its more powerful cannon. In general the two helicopters have similar flight performance. Two Klimov TV-3-117 engines of 2,200 hp each allow the Russian aircraft to show a maximum level speed of 300 km/h and maximum climb at sea-level of 13.6 meters per second. Mi-28 Havoc (wallpaper 1).

The Bell AH-1 SuperCobra is a twin-engine attack helicopter based on the US Army's AH-1 Cobra. The twin Cobra family includes the AH-1J SeaCobra, the AH-1T Improved SeaCobra, and the AH-1W SuperCobra. The AH-1W is the backbone of the United States Marine Corps's attack helicopter fleet, but will be replaced in service by the Bell AH-1Z Viper upgrade in the next decade. The AH-1 Cobra was developed in the mid-1960s as an interim gunship for the U.S. Army for use in Vietnam. The Cobra shared the proven transmission, rotor system, and the T53 turboshaft engine of the UH-1 "Huey". By June 1967, the first AH-1G HueyCobras had been delivered. Bell built 1,116 AH-1Gs for the U.S. Army between 1967 and 1973, and the Cobras chalked up over a million operational hours in Vietnam. The U.S. Marine Corps was very interested in the AH-1G Cobra, but preferred a twin-engined version for improved safety in over-water operations, and also wanted a more potent turret-mounted weapon. AH-1W Super Cobra (wallpaper 1). AH-1W Super Cobra aircraft images wallpaper gallery 1. AH-1W Super Cobra airplane pictures and images collection 1. At first, the Department of Defense had balked at providing the Marines with a twin-engined version of the Cobra, in the belief that commonality with Army AH-1Gs outweighed the advantages of a different engine fit. However, the Marines won out and awarded Bell a contract for 49 twin-engined AH-1J SeaCobras in May 1968. As an interim measure, the U.S. Army passed on 38 AH-1Gs to the Marines in 1969. The AH-1J also received a more powerful gun turret. It featured a three barrel 20 mm XM197 cannon that was based on the six barrel M61 Vulcan cannon. The Marine Corps requested greater load carrying capability in high temperatures for the Cobra in the 1970s. Bell used systems from its Model 309 to develop the AH-1T. This version had a lengthened tailboom and fuselage with an upgraded transmission and engines from the 309. Bell designed the AH-1T to be more reliable and easier to maintain in the field. The version was given full TOW missile capability with targeting system and other sensors. An advanced version, known as the AH-1T+ with more powerful T700-GE-700 engines and advanced avionics was proposed to Iran in the late 1970s, but the overthrow of the Shah of Iran resulted in the sale being canceled.

The Boeing CH-47 Chinook is a twin-engine, tandem rotor heavy-lift helicopter. Its top speed of 170 knots (196 mph, 315 km/h) was faster than contemporary utility and attack helicopters of the 1960s. It is one of the few aircraft of that era, such as the C-130 Hercules and the UH-1 Iroquois, that is still in production and front line service with over 1,179 built to date. Its primary roles include troop movement, artillery emplacement and battlefield resupply. It has a wide loading ramp at the rear of the fuselage and three external-cargo hooks. The Chinook was designed and initially produced by Boeing Vertol in the early 1960s. The helicopter is now produced by Boeing Rotorcraft Systems. Chinooks have been sold to 16 nations with the US Army and the Royal Air Force (see Boeing Chinook (UK variants)) being the largest users. The CH-47 is among the heaviest lifting Western helicopters. As with any new piece of equipment, the Chinook presented a major problem of "customer education". CH-47 Chinook (wallpaper 1). CH-47 Chinook aircraft images wallpaper gallery 1. CH-47 Chinook airplane pictures and images collection 1. Commanders and crew chiefs had to be constantly alert that eager soldiers did not overload the temptingly large cargo compartment. It would be some time before troops would be experts at using sling loads. The Chinook soon proved to be such an invaluable aircraft for artillery movement and heavy logistics that it was seldom used as an assault troop carrier. Some of the Chinook fleet were used for casualty evacuation, due to the very heavy demand for the helicopters they were usually overburdened with wounded. Perhaps the most cost effective use of the Chinook was the recovery of other downed aircraft. The Chinooks were generally armed with a single 7.62 millimeter M60 machine gun on a pintle mount on either side of the machine for self-defense, with stops fitted to keep the gunners from firing into the rotor blades. Dust filters were also added to improve engine reliability. At its peak employment in Vietnam, there were 22 Chinook units in operation. Of the nearly 750 Chinooks in the US and Republic of Vietnam fleets, about 200 were lost in combat or wartime operational accidents. US Army supplied Chinooks to the Australian Task Force as required. CH-47 Chinook (wallpaper 1). CH-47 Chinook aircraft images wallpaper gallery 1.

The AW129 multirole combat helicopter is the latest variant of the A129 Mangusta (Mongoose) helicopter in service with the Italian Army. It is manufactured by AgustaWestland, a joint venture company, which was originally formed by Finmeccanica of Italy and GKN of the UK, but is now solely owned by Finmeccanica. The A129 International was renamed AW129 in 2007. The AW129 is a multirole helicopter for armed reconnaissance and surveillance, high-value ground-target engagement, escort, fire support, and air-threat suppression. It is armed with new powerful air-to-ground and air-to-air missiles, an off-axis cannon and an increased weapon payload. The five-bladed A129 International also has more powerful engines than the four-bladed Mangusta. The Italian Army is equipped with 60 A129 Mangusta helicopters and 15 AW129, referred to as A129 CBT (combat configuration). A129 Mangusta (wallpaper 1). A129 Mangusta aircraft images wallpaper gallery 1. A129 Mangusta airplane pictures and images collection 1. In January 2002, AgustaWestland was awarded a contract to upgrade the first 45 to the multirole standard. The upgrade included: five-blade composite main rotor and two-blade tail rotor, Rolls-Royce Gem 1004 engines, new stronger transmission with a torque of 1,700shp, strengthened fuselage giving an increase in take-off weight to 4,600kg, improved weapons systems including Oto Melara 197B 20mm nose-mounted cannon and the Stinger air-to-air missiles, new FLIR (forward-looking infrared) system, improved countermeasures suite including EADS AN/AAR-60 missile launch detector and new global positioning / inertial navigation (GPS/INS) system. Deliveries concluded in July 2008. The Mangusta has been successfully deployed with UN operations in Somalia, Angola and Kosovo. Italian Army A129 helicopters have been deployed in Iraq as part of Operation Iraqi Freedom and were deployed to Afghanistan in summer 2007, as part of the Nato International Security Force.

A total of 172 Super Stallions have been delivered and 165 are in service with marine corps squadrons in the Pacific Fleet and in the Atlantic Fleet. The helicopter is also in service with the marine corps reserve, training and experimental squadrons. The final Super Stallion for the USMC was delivered in November 2003. The marine corps uses the Super Stallion in the amphibious assault role and for transporting heavy equipment. The US Navy also use the Super Stallion for vertical delivery and recovery of damaged aircraft on aircraft carriers. CH-53E Super Stallion (wallpaper 1). CH-53E Super Stallion aircraft images wallpaper gallery 1. CH-53E Super Stallion airplane pictures collection 1. In 2000, the USMC announced the CH-53X programme to upgrade the CH-53E and extend its service life to 2025. Upgrades would include a new engine, substantially increased payload capacity, all-composite rotor, elastomeric rotor head and glass cockpit with fly-by-wire controls. In March 2004, a USMC analysis of alternatives (AoA) determined that a new-build airframe would be a more cost-effective solution. Sikorsky was awarded an initial system development and demonstration (SDD) contract for the new helicopter, which is designated CH-53K heavy-lift rotorcraft (HLR), in January 2006 and the full SDD contract in April 2006. The GE38-1B engine was selected to power the CH-53K in December 2006. Requirement is for 156 helicopters and service entry is planned for 2015. The fuselage is watertight and of light alloy, steel and titanium construction. The cockpit includes glass fibre and epoxy materials. The seven-bladed main rotor is fitted with a Sikorsky blade inspection system. The main rotor blades are of Nomex honeycomb construction with a titanium spar and a composite glass fibre and epoxy skin. The rotor head is primarily titanium and steel.

The Ka-50 Black Shark helicopter, developed by Kamov Helicopters JSC, carries the Nato codename Hokum A, with Hokum B the two-seat version, Ka-52. Ka-50 is also known as Werewolf. It is a high-performance combat helicopter with day and night capability, high survivability and fire power to defeat air targets and heavily armoured tanks armed with air defence weapons. It entered service with the Russian Army during 1995 and is manufactured at the Sazykin Aviation Company Progress based in Arseniev Maritime Territory, Russia. A first batch of eight Ka-50 aircraft has been delivered. 12 Ka-52 were to be procured for Russian Air Force special operations in 2005, but funding for the programme has been cut from the 2005 budget. Kamov Ka-50 Black Shark (wallpaper 1). Kamov Ka-50 Black Shark aircraft images wallpaper gallery 1. Kamov Ka-50 Black Shark airplane pictures collection 1. As of late 2008, the Russian Air Force operated 15 Ka-50 and ten Ka-52 helicopters. A night attack version, Ka-50N, with Samshit-50T thermal imager, day TV and laser rangefinder has been developed, and Kamov has also joined with Israeli Aircraft Industries (IAI) to produce a version, the Ka-50-2 Erdogan that is compatible with Nato weapons and has an Israeli equipped cockpit. The coaxial rotor design provides a hovering ceiling of 4,000m and vertical rate of climb of 10m a second at an altitude of 2,500m. The rotor blades are made from polymer materials. The coaxial-rotor configuration results in moments of inertia values relative to vertical and lateral axes between 1.5 to two times less than the values found in single-rotor helicopters with tail rotors. Absence of the tail rotor enables the helicopter to perform flat turns within the entire flight speed range. A maximum vertical g-load of 3.5 combined with low moments of inertia give the Ka-50 a high level of agility. Kamov Ka-50 Black Shark (wallpaper 1).

The Eurocopter Tiger (company designation EC 665) is an attack helicopter manufactured by Eurocopter. In Germany it is known as the Tiger; in France and Spain it is called the Tigre. In 1984, the West German and French governments issued a requirement for an advanced multi-role battlefield helicopter. A joint venture consisting of MBB and Aérospatiale was subsequently chosen as the preferred supplier. Due to high costs, the program was cancelled in 1986, but was relaunched during 1987. Subsequently, in November 1989, Eurocopter received a contract to build five prototypes. Three were to be unarmed testbeds and the other two armed prototypes: one for the German anti-tank variant and the other for the French escort helicopter variant. The first prototype first flew in April 1991. When Aérospatiale and MBB, among others, merged in 1992 to form the Eurocopter Group, the Tiger program was transferred as well. Eurocopter Tiger EC 665 (wallpaper 1). Eurocopter Tiger EC 665 aircraft images wallpaper gallery 1. Eurocopter Tiger EC 665 airplane pictures collection 1. Serial production of the Tiger began in March 2002 and the first flight of the first production Tiger HAP for the French Army took place in March 2003. The delivery of the first of the eighty helicopters ordered by the French took place in September 2003. At the end of 2003, deliveries began of the 80 UHT version combat support helicopters ordered by Germany to the Federal Office of Defense Technology and Procurement. Due to technical problems, operational capability is not expected to be achieved before the end of 2012 at the latest. In December 2001, Eurocopter was awarded the contract for the Australian Army's "AIR 87 requirement", which was for 22 helicopters of the Tiger ARH (Armed Reconnaissance Helicopter) version. The first Tiger ARH was scheduled to enter service in 2004. 18 of the 22 aircraft will be assembled at the Brisbane facility of Australian Aerospace, the local Eurocopter subsidiary in Australia. However, because of the delay in attaining operational capability, Australia's Defence Materiel Organisation had to stop payment for the helicopters on 1 July 2007. By 2008 the main issues had been addressed and payments resumed. However, in October 2010 it was revealed that the helicopters will not be fully operational for another two years.

The Boeing AH-64 Apache is a four-blade, twin-engine attack helicopter with tailwheel-type landing gear arrangement, and tandem cockpit for a crew of two. The Apache was developed as Model 77 by Hughes Helicopters for the United States Army's Advanced Attack Helicopter program to replace the AH-1 Cobra. First flown on 30 September 1975, the AH-64 features a nose-mounted sensor suite for target acquisition and night vision systems. The Apache is armed with a 30-millimeter (1.2 in) M230 Chain Gun carried between the main landing gear, under the aircraft's forward fuselage. It has four hardpoints mounted on stub-wing pylons, typically carrying a mixture of AGM-114 Hellfire and Hydra 70 rocket pods. The AH-64 also features double- and triple-redundant aircraft systems to improve survivability for the aircraft and crew in combat, as well as improved crash survivability for the pilots. AH-64 Apache (wallpaper 1). AH-64 Apache aircraft images wallpaper gallery 1. AH-64 Apache aircraft pictures collection 1. The U.S. Army selected the AH-64 over the Bell YAH-63 in 1976, awarding Hughes Helicopters a pre-production contract for two more aircraft. In 1982, the Army approved full production. McDonnell Douglas continued production and development after purchasing Hughes Helicopters from Summa Corporation in 1984. The first production AH-64D Apache Longbow, a greatly upgraded version of the original Apache, was delivered to the Army in March 1997. AH-64 production is continued by the Boeing Defense, Space & Security division; over one thousand AH-64s have been produced to date. The U.S. Army is the primary operator of the AH-64, however it has also become the primary attack helicopter of several nations it has been exported to, including the United Kingdom, Israel, Japan, Greece and the Netherlands. U.S. AH-64s have served in conflicts in Panama, Persian Gulf War, Kosovo War, Afghanistan, and Iraq. Israel has made active use of the Apache in its military conflicts in Lebanon and Gaza Strip; while two coalition allies have deployed their AH-64s in Afghanistan and Iraq.

Helicopter Aircraft. helicopter, Aircraft with one or more power-driven horizontal rotors that enable it to take off and land vertically, move in any direction, or remain stationary in the air. Since a rotor is essentially a rotating airfoil, a helicopter is often described as a rotary-wing aircraft, in contrast to a conventional fixed-wing airplane. One of the earliest ideas for flying, it appeared in China and Renaissance Europe as a toy and in Leonardo da Vinci’s designs. The Frenchman Paul Cornu made the first manned flight in 1907. Igor Sikorsky produced the first successful prototype in 1939, which was followed. A helicopter is a type of rotorcraft in which lift and thrust are supplied by one or more engine driven rotors. In contrast with fixed-wing aircraft, this allows the helicopter to take off and land vertically, to hover, and to fly forwards, backwards and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft would not be able to take off or land. The capability to efficiently hover for extended periods of time allows a helicopter to accomplish tasks that fixed-wing aircraft and other forms of vertical takeoff and landing aircraft cannot perform. The word 'helicopter' is adapted from the French hélicoptère, coined by Gustave de Ponton d'Amecourt in 1861, which originates from the Greek helix/helik- (ἕλιξ) = "twisted, curved" and pteron (πτερόν) = "wing". Helicopters were developed and built during the first half-century of flight, with the Focke-Wulf Fw 61 being the first operational helicopter in 1936. Some helicopters reached limited production, but it was not until 1942 that a helicopter designed by Igor Sikorsky reached full-scale production, with 131 aircraft built. Though most earlier designs used more than one main rotor, it was the single main rotor with antitorque tail rotor configuration of this design that would come to be recognized worldwide as the helicopter.
