Turbomeca Artouste
The Turbomeca Artouste is an early French turboshaft engine, first run in 1947. Originally conceived as an auxiliary power unit (APU), it was soon adapted to aircraft propulsion, and found a niche as a powerplant for turboshaft-driven helicopters in the 1950s. Artoustes were licence-built by Bristol Siddeley (formerly Blackburn) in the UK, Hindustan Aeronautics Limited in India, and developed by Continental CAE in the US as the Continental T51. Two major versions of the Artouste were produced. The Artouste II family, mainly used in the Aérospatiale Alouette II helicopter, had a one-stage centrifugal compressor and a two-stage turbine, with gearbox-limited power of . The Artouste III family, mainly used in Aérospatiale's Alouette III and Lama helicopters, had a two-stage axial-centrifugal compressor and a three-stage turbine, with gearbox-limited power of .

Propeller Speed Reduction Unit
A propeller speed reduction unit is a gearbox or a belt and pulley device used to reduce the output revolutions per minute (rpm) from the higher input rpm of the powerplant.Gunston 2006, p. 82. This allows the use of small displacement internal combustion engines to turn aircraft propellers within an efficient speed range. History and operation The Wright brothers recognised the need for propeller reduction gearing in 1903, but it was not generally used on aircraft engines until larger engines were designed in the 1920s. Large engines with high crankshaft speeds and power outputs demanded propeller reduction, pilots noted the increase in performance of similar aircraft fitted with reduction gearing. Types Types of propeller speed reduction units include: *Chain drive *Single reduction or spur gear *Internal spur gear *Farman or bevel planetary type *Fixed sun gear *Fixed internal gear *Belt drive *Epicyclic gearing Design variations The Rolls-Royce Falcon engine of 1915 fea ...

Vickers VC10
The Vickers VC10 is a mid-sized, narrow-body long-range British jet airliner designed and built by Vickers-Armstrongs (Aircraft) Ltd and first flown at Brooklands, Surrey, in 1962. The airliner was designed to operate on long-distance routes from the shorter runways of the era and commanded excellent hot and high performance for operations from African airports. The performance of the VC10 was such that it achieved the fastest crossing of the Atlantic by a subsonic jet airliner of 5 hours and 1 minute, a record that was held for 41 years, until February 2020 when a British Airways Boeing 747 broke the record at 4 hours 56 minutes due to Storm Ciara. Only the supersonic Concorde was faster. The VC10 is often compared to the larger Soviet Ilyushin Il-62, the two types being the only airliners to use a rear-engined quad layout. The smaller business jet Lockheed JetStar also has this engine arrangement. Although only a relatively small number of VC10s were built, they provide ...

Piasecki VZ-8 Airgeep
The Piasecki VZ-8 Airgeep (company designation PA-59) was a prototype vertical takeoff and landing (VTOL) aircraft developed by Piasecki Aircraft. The Airgeep was developed to fulfill a U.S. Army Transportation Research Command contract for a flying jeep in 1957. The flying jeep was envisioned to be smaller and easier to fly than a helicopter. Design and development To meet the US Army's requirement, Piasecki's design featured two tandem, three-blade ducted rotors, with the crew of two seated between the two rotors. Power was by two Lycoming O-360-A2A piston engines, driving the rotors by a central gearbox. The first of two aircraft ordered by the Army, initially designated the Model 59K Skycar (and later renamed Airgeep) by Piasecki and designated VZ-8P by the Army, flew on 22 September 1958.Harding 1998, p.11.PA-59K: ''Histor ...

Nord Norelfe
__NOTOC__ The Nord 1750 Norelfe was a 1950s French three-seat helicopter built by Nord Aviation and designed by Jean Cantinieau. Development The 1750 Norelfe was based on the Matra-Cantinieau MC-101A, an earlier helicopter designed by Jean Cantinieau. It had a single main rotor, with torque control through a movable duct at the end of the tailboom. Powered by a Turbomeca Artouste turboshaft, the first of two Norelfes flew on 28 December 1954. The company sold the two helicopters and the design rights to Aerotécnica of Spain who redesignated them the Aerotécnica AC-13A.

Merckle SM 67
The Merckle SM 67 was an experimental helicopter built in West Germany in the late 1950s. Design The SM 67 was the first turbine-powered helicopter in Germany. The German Federal Ministry of Defense commissioned the development in 1957. The design of the SM 67 was similar to that of the Alouette II, including a metal frame of the rear fuselage. The first prototype flew on July 7, 1959, and flight tests revealed remarkably low vibration level as well as good controllability and stability. Therefore, two more prototypes were built, in which the experience gained with the first prototype was taken into account. However, the first prototype was destroyed during tests, and the Bundeswehr opted for the SE-3130 Alouette II rather than the SM 67 due to the earlier availability of the former.Thomas Seitz: Hubschrauber-Entwicklung in Oedheim, Oedheimer Hefte Nr. 11 – Beiträge zur Oedheimer und Degmarner Geschichte, 2009, ohne ISBN Surviving examples The second prototype was used at MBB ...

IAR 316
The IAR 316 is a Romanian license-built Aérospatiale SA 316B Alouette III manufactured by Industria Aeronautică Română (IAR). Design and development IAR 316 IAR began manufacturing the IAR 316 in 1971 at its plant near Brașov, Romania. Production ended in 1987. 250 units were built, 125 of those were built for the Military of Romania, which still uses it to this day in a training capacity. Some IAR 316s were operated in the civilian role in Romania and others were exported to various nations, including Pakistan, Angola, and Guinea. The IAR 316 was modified to carry weapons more common in the Eastern-bloc, such as 57mm rocket pods, 7.62mm machine guns, and anti-tank missiles. An early example was exhibited at the Paris Air Show in June 1973. IAR 317 The IAR 317 Airfox was an attempt by IAR to make an attack helicopter out of the IAR 316. Equipped with the same license-produced Turbomeca Artouste IIIB turboshaft, the IAR 317 featured a stepped two-seat armored cockpit for ...

Hawker Siddeley Trident
The Hawker Siddeley HS-121 Trident (originally the de Havilland DH.121 and briefly the Airco DH.121) is a British airliner produced by Hawker Siddeley. In 1957, de Havilland proposed its DH.121 trijet design to a British European Airways (BEA) request. By 1960, de Havilland had been acquired by Hawker Siddeley. The Trident's maiden flight happened on 9 January 1962, and it was introduced on 1 April 1964, two months after its main competitor, the Boeing 727. By the end of the programme in 1978, 117 Tridents had been produced. The Trident was withdrawn from service in 1995. The jetliner is powered by three rear-mounted Rolls-Royce Spey low-bypass turbofans, it has a low swept wing and a T-tail. Advanced avionics allowed it to be the first airliner to make a blind landing in revenue service in 1965. The initial Trident 1/2 could seat 101-115 passengers over up to . The Trident 3 was stretched by to seat 180 over , and had an additional RB.162 booster engine in the tail. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auxiliary Power Unit
An auxiliary power unit (APU) is a device on a vehicle that provides energy for functions other than propulsion. They are commonly found on large aircraft and naval ships as well as some large land vehicles. Aircraft APUs generally produce 115 V AC voltage at 400 Hz (rather than 50/60 Hz in mains supply), to run the electrical systems of the aircraft; others can produce 28 V DC voltage. APUs can provide power through single or three-phase systems. Transport aircraft History During World War I, the British Coastal class blimps, one of several types of airship operated by the Royal Navy, carried a ABC auxiliary engine. These powered a generator for the craft's radio transmitter and, in an emergency, could power an auxiliary air blower. One of the first military fixed-wing aircraft to use an APU was the British, World War 1, Supermarine Nighthawk, an anti-Zeppelin night fighter.Andrews and Morgan 1987, p. 21. During World War II, a number of large Ameri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handley Page Victor
The Handley Page Victor is a British jet-powered strategic bomber developed and produced by Handley Page during the Cold War. It was the third and final '' V bomber'' to be operated by the Royal Air Force (RAF), the other two being the Avro Vulcan and the Vickers Valiant. Entering service in 1958, the Victor was initially developed as part of the United Kingdom's airborne nuclear deterrent, but it was retired from the nuclear mission in 1968, following the discovery of fatigue cracks which had been exacerbated by the RAF's adoption of a low-altitude flight profile to avoid interception, and due to the pending introduction of the Royal Navy's submarine-launched Polaris missiles in 1969. With the nuclear deterrent mission relinquished to the Royal Navy a large V-bomber fleet could not be justified. A number of Victors were modified for strategic reconnaissance, using a combination of radar, cameras, and other sensors. Prior to the introduction of Polaris, some had already be ...

Curtiss-Wright VZ-7
The Curtiss-Wright VZ-7 (also known as the VZ-7AP) was a VTOL quadrotor helicopter aircraft designed by the Curtiss-Wright company for the US Army. Like the Chrysler VZ-6 and the VZ-8 Airgeep it was to be a "flying jeep". Design and development The Aerophysics Development Corporation, a subsidiary of Curtiss-Wright, designed an "Aerial Platform" for a US Army Transport and Research Command "Flying Jeep" design competition. The Aerophysics design sat two in tandem between four ducted fan rotors and could also be armed with machine-guns or recoil-less rifles. To prove the design concept the US Army ordered two prototypes of a smaller single-seat demonstrator, the VZ-7, which were delivered to the US Army in mid-1958. The VZ-7 had a fuselage with the pilot's seat, fuel tanks and flight controls. On both sides of the fuselage the four propeller/rotors were attached, unshrouded (the aircraft did originally have shrouds, but these were later removed). The VZ-7 was controlled by chang ...
