Westland Lynx
The Westland Lynx is a British multi-purpose twin-engined military helicopter designed and built by Westland Helicopters at its factory in Yeovil. Originally intended as a utility craft for both civil and naval usage, military interest led to the development of both battlefield and naval variants. The Lynx went into operational usage in 1977 and was later adopted by the armed forces of over a dozen nations, primarily serving in the Utility helicopter, battlefield utility, anti-tank warfare, anti-armour, search and rescue and anti-submarine warfare roles. The Lynx is a fully aerobatics, aerobatic helicopter with the ability to perform loops and rolls. In 1986, a specially modified Lynx set the current Fédération Aéronautique Internationale's official airspeed record for helicopters (category excludes compound helicopters) at , which remains unbroken as of January 2022.

Fédération Aéronautique Internationale
The World Air Sports Federation (; FAI) is the world governing body for air sports, and also stewards definitions regarding human spaceflight. It was founded on 14 October 1905, and is headquartered in Lausanne, Switzerland. It maintains world records for aeronautical activities, including ballooning, aeromodeling, and unmanned aerial vehicles (drones), as well as flights into space. History The FAI was founded at a conference held in Paris 12–14 October 1905, which was organized following a resolution passed by the Olympic Congress held in Brussels on 10 June 1905 calling for the creation of an Association "to regulate the sport of flying, ... the various aviation meetings and advance the science and sport of Aeronautics." The conference was attended by representatives from 8 countries: Belgium (, founded 1901), France ( Aéro-Club de France, 1898), Germany ( aka "German Airship League", founded 1902), Great Britain (Royal Aero Club, 1901), Italy (, 1904), Spain (, 19 ...

BERP Rotor
The BERP rotor blade design was developed under the ''British Experimental Rotor Programme''. The initial BERP rotor blades were developed in the late 1970s to mid-1980s as a joint venture programme between Westland Helicopters and the Royal Aircraft Establishment (RAE), with Professor Martin Lowson as a co-patentee. The goal was to increase the helicopters lifting-capability and maximum speed using new designs and materials. How it works As objects approach the speed of sound, shock waves form in areas where the local flow is accelerated above the speed of sound. This normally occurs on curved areas, like cockpit windows, leading edges of the wing, and similar areas where Bernoulli's principle accelerates the air. These shock waves radiate away a great amount of energy that has to be supplied by the engines, which appears to the aircraft as a whole as a large amount of additional drag, known as wave drag. It was the onset of wave drag that gives rise to the idea of a sound ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aérospatiale Gazelle
The Aérospatiale Gazelle (company designations SA 340, SA 341 and SA 342) is a five-seat helicopter developed and initially produced by the French aircraft company Sud Aviation, and later by Aérospatiale. It is the first helicopter to feature a fenestron tail instead of a conventional tail rotor, as well as being the first helicopter to be adapted for single-pilot operations under instrument flight rules. The Gazelle was developed during the 1960s as a successor to the Aérospatiale Alouette II, Alouette II as well as to meet a French Army requirement for a new lightweight observation helicopter. The Gazelle is considerably larger than the preceding Alouette series, yet is still powered by a single Turbomeca Astazou Gas turbine, turbine engine. Innovations in the design of the Gazelle, aside from the fenestron, included an emphasis on minimal maintenance requirements from the onset of development and the use of a Helicopter rotor#Semirigid, semi-rigid composite materials, com ...

Turboshaft
A turboshaft engine is a form of gas turbine that is optimized to produce shaft horsepower rather than jet thrust. In concept, turboshaft engines are very similar to turbojets, with additional turbine expansion to extract heat energy from the exhaust and convert it into output shaft power. They are even more similar to turboprops, with only minor differences, and a single engine is often sold in both forms. Turboshaft engines are commonly used in applications that require a sustained high power output, high reliability, small size, and light weight. These include helicopters, auxiliary power units, boats and ships, tanks, hovercraft, and stationary equipment. Overview A turboshaft engine may be made up of two major parts assemblies: the 'gas generator' and the 'power section'. The gas generator consists of the Gas compressor, compressor, combustion chambers with ignitors and fuel nozzles, and one or more stages of turbine. The power section consists of additional stages of turbi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolls-Royce Gem
The Rolls-Royce Gem is a turboshaft engine developed specifically for the Westland Lynx helicopter in the 1970s. The design started off at de Havilland Engine division (hence the name starting with "G") and passed to Bristol Siddeley as the BS.360. Rolls-Royce bought out Bristol Siddeley in 1966 and after it dropped the Bristol Siddeley identity the engine became the RS.360. Design and development The Gem's three-shaft engine configuration is rather unusual for turboshaft/turboprop engines. Basic arrangement is a four-stage axial LP (Low Pressure) compressor, driven by a single stage LP turbine, supercharging a centrifugal HP (High Pressure) compressor, driven by a single stage HP turbine. Power from a two-stage free (power) turbine is delivered to the load via a third shaft. A reverse flow combustor is featured. The Gem 42 develops at Take-off, Sea Level Static, ISA, but the Maximum Contingency Rating (MCR) is . Until recently all versions of the Lynx have been Gem powered ...

UH-1 Iroquois
The Bell UH-1 Iroquois (nicknamed "Huey") is a utility military helicopter designed and produced by the American aerospace company Bell Helicopter. It is the first member of the prolific Huey family, as well as the first turbine-powered helicopter in service with the United States military. Development of the Iroquois started in the early 1950s, a major impetus being a requirement issued by the United States Army for a new medical evacuation and utility helicopter. The Bell 204, first flown on 20 October 1956, was warmly received, particularly for the performance of its single turboshaft engine over piston engine-powered counterparts. An initial production contract for 100 ''HU-1A''s was issued in March 1960. In response to criticisms over the rotorcraft's power, Bell quickly developed multiple models furnished with more powerful engines; in comparison to the prototype's Lycoming YT53-L-1 (LTC1B-1) engine, producing , by 1966, the Lycoming T53-L-13, capable of , was being i ...
