Skyvan
The Short SC.7 Skyvan (nicknamed the "Flying Shoebox") is a British 19-seat twin-turboprop aircraft first flown in 1963, that was manufactured by Short Brothers of Belfast, Northern Ireland. Featuring a basic rugged design and STOL capabilities, it was used in small numbers by airlines, and also by some smaller air forces. In more recent years the remaining examples were mostly used for short-haul freight and skydiving. The Short 330 and Short 360 are regional airliners developed from the original SC.7. Design and development In 1958, Short was approached by F.G. Miles Ltd (successor company to Miles Aircraft) which was seeking backing to produce a development of the Hurel-Dubois Miles HDM.106 Caravan design with a high aspect ratio wing similar to that of the Hurel-Dubois HD.31. Short acquired the design and data gathered from trials of the Miles Aerovan based HDM.105 prototype. After evaluating the Miles proposal, Short rejected the Caravan. They developed their own desi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short Brothers
Short Brothers plc, usually referred to as Shorts or Short, is an aerospace company based in Belfast, Northern Ireland. Shorts was founded in 1908 in London, and was the first company in the world to make production aeroplanes. It was particularly notable for its flying boat designs manufactured into the 1950s. In 1943, Shorts was Nationalization, nationalised and later denationalised, and in 1948 moved from its main base at Rochester, Kent to Belfast. In the 1960s, Shorts mainly produced turboprop airliners, major components for aerospace primary manufacturers, and missiles for the British Armed Forces. Shorts was primarily HM Government, government-owned until being bought by Bombardier Inc., Bombardier in 1989 and, in 2007, was the largest manufacturing concern in Northern Ireland. In November 2020, Bombardier sold its Belfast operations to Spirit AeroSystems. The company's products include aircraft components, engine nacelles and aircraft flight control systems for Bomba ...

Short 330
The Short 330 (also SD3-30) is a small turboprop transport aircraft produced by Short Brothers. It seats up to 30 people and was relatively inexpensive and had low maintenance costs at the time of its introduction in 1976. The 330 was based on the SC.7 Skyvan. The C-23 Sherpa was a military version of the 330. Production of the aircraft ended in 1992, after 141 were produced. The Short 360 was a development of the Short 330. Development The Short 330 was developed by Short Brothers of Belfast from Short's earlier Short Skyvan STOL utility transport. The 330 had a longer wingspan and fuselage than the Skyvan, while retaining the Skyvan's square-shaped fuselage cross section, allowing it to carry up to 30 passengers while retaining good short field characteristics.Donald, David, ed. ''The Encyclopedia of World Aircraft''. London: Aerospace Publishing, 1997. . The first prototype of the 330 flew on 22 August 1974.Taylor 1988, p. 304. The Short 330 is unusual in having all of i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C-23 Sherpa
The Short C-23 Sherpa is a small military transport aircraft built by Short Brothers. It was designed to operate from unpaved runways and make STOL, short takeoff and landings (STOL). It features a large squared fuselage with a full-width rear cargo door/ramp. The ''C-23A'' and ''C-23B'' are variants of the Short 330 and the ''C-23B+'' is a variant of the Short 360. 60 aircraft were used, it was finally retired from US Army in 2014, but remains in international service. Although it went on to be used for other uses, it was originally the winner of an early 1980s competition for a light cargo aircraft to deliver cargo, especially aviation parts in Western Europe (EDSA). While the C-23 was a new production, as was the C-23B, the C-23B+ were actually Shorts 360, with the tail and rear fuselage of a C-23. One of the differences between the C-23 and C-23B, is that the latter had cabin windows. The aircraft has a substantial amount of civilian use and was also operated by the U.S. Fo ...

Short 360
The Short 360 (also SD3-60; also Shorts 360)Mondey, David. ''Encyclopedia of the World's Commercial and Private Aircraft''. New York: Crescent Books, 1981. , p. 228. is a commuter aircraft that was built by UK manufacturer Short Brothers during the 1980s. The Short 360 seats up to 39 passengers and was introduced into service in November 1982. It is a larger version of the Short 330. Development During the 1970s, the world's commuter airline market began to evolve from the 20-seat class to larger and more comfortable cabins. Short Brothers of Northern Ireland had created the Short SC.7 Skyvan, Skyvan in 1962, followed by the related but larger Short 330 in 1974. The Short 360 development was announced in 1980, with the prototype's first flight on 1 June 1981 and Type certificate, type certification awarded on 3 September 1981. The first production Short 360 had its maiden flight on 19 August 1982 and entered service with Suburban Airlines (later merged with Allegheny Airline ...

Skydiving
Parachuting and skydiving are methods of descending from a high point in an atmosphere to the ground or ocean surface with the aid of gravity, involving the control of speed during the descent using a parachute or multiple parachutes. For human skydiving, there is often a phase of free fall (the skydiving segment), where the parachute has not yet been deployed and the body gradually accelerates to terminal velocity. In cargo parachuting, the parachute descent may begin immediately, such as a parachute-airdrop in the Troposphere, lower atmosphere of Earth, or it may be significantly delayed. For example, in a planetary atmosphere, where an object is descending "under parachute" following atmospheric entry from outer space, space, may occur only after the hypersonic entry phase and initial deceleration that occurs due to aerodynamic drag, friction with the thin upper atmosphere. History The first parachute jump in history was made on 22 October 1797 by Frenchman André-Jacq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mid-air Retrieval
Mid-air retrieval is a technique used in atmospheric reentry when the reentering vehicle is incapable of a satisfactory unassisted landing. The vehicle is slowed by means of parachutes, and then a specially-equipped aircraft matches the vehicle's trajectory and catches it in mid-air. This is a risky technique, and so is only used when other forms of landing are infeasible. Successful mid-air retrieval requires correct operation of the retrieving aircraft, favourable atmospheric conditions, and successful execution of a tricky manoeuvre, in addition to correct operation of the vehicle itself. These risks can be mitigated somewhat: for example, multiple recovery aircraft can be used. The need for human aviators to perform a manoeuvre which would normally be classed as a stunt may in the future be avoided by advances in unmanned aerial vehicles and spacecraft reentry. Notable uses of the technique: * The first use of midair retrieval was in 1955, with Fairchild C-119 Flying Boxcar t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miles Aircraft
Miles was the name used for aircraft and associated businesses of British engineer Frederick George Miles, who, with his wife – aviator and draughtswoman Maxine Blossom Miles, Maxine "Blossom" Miles (née Forbes-Robertson) – and his brother George Herbert Miles, designed numerous light civil and military aircraft and a range of curious prototypes, primarily between 1943 and 1947. History Phillips and Powis A company was founded in 1928 by Charles Powis and Jack Phillips as Phillips & Powis Aircraft (Reading) Ltd. In 1929 they opened Woodley Aerodrome, near the town of Reading, Berkshire, Reading, Berkshire. In 1936, Rolls-Royce Limited, Rolls-Royce bought into the company. Although aircraft were produced under the Miles name, it was not until 1943 that the firm became Miles Aircraft Limited when Rolls-Royce's interests were bought out. The company needed to increase production of the Miles Messenger and to do so it took over a former linen mill in Banbridge, County Dow ...

Turbomeca Astazou
The Turbomeca Astazou is a highly successful series of turboprop and turboshaft engines, first run in 1957. The original version weighed and developed at 40,000 rpm. It was admitted for aviation service on May 29, 1961, after a 150-hour test run. The main developing engineer was G. Sporer. It was named after two summits of the Pyrenees. A simplified version was built by Agusta as the Turbomeca-Agusta TA.230. Design and development The Astazou IIA version was derived from the original Astazou powerplant for use in helicopters. By 1993, 2,200 had been built. As of 2007, it was still in production. However, many aircraft initially equipped with it, especially the heavier ones, have since been upgraded with more powerful engines. The early single-shaft Astazou has a two-stage compressor, with the first stage an axial and the second stage a radial design. It has an annular combustion chamber, after which the combustion gases enter a three-stage axial turbine. Engines have a redu ...

Garrett TPE331
The Honeywell TPE331 (military designation: T76) is a turboprop engine. It was designed in the 1950s by Garrett AiResearch, and produced since 1999 by successor Honeywell Aerospace. The engine's power output ranges from . Design and development Garrett AiResearch designed the TPE331 from scratch in 1959 for the military. “Designed as a 575-horsepower engine it was not a scaled-down version of a larger engine, as competitors were offering.” The TPE331 originated in 1961 as a gas turbine (the "331") to power helicopters. It first went into production in 1963. More than 700 had been shipped by the end of 1973. It was designed to be both a turboshaft A turboshaft engine is a form of gas turbine that is optimized to produce shaft horsepower rather than jet thrust.

Miles Aerovan
The Miles M.57 Aerovan was a British twin-engined short-range low-cost transport aircraft designed and produced by Miles Aircraft. It was primarily used for freight and passenger services. Development of the Aerovan started during the latter years of the Second World War as an affordable freighter suitable for both civilian and military purposes. It was suited to austere operations, and possessed an atypically high payload capacity for its power output. Relatively large payloads, including a single car, could be transported by the aircraft, being loaded via its large clamshell freight door. While Miles intended to produce the Aerovan for the British Army as a wartime asset, development was put on hold by order of the Air Ministry until the end of the conflict. On 26 January 1945, the maiden flight of the Aerovan took place. Quantity production formally commenced during 1946, although customer demand exceeded the company's production capacity. The Aerovan was primarily flown by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regional Airliner
A regional airliner, commuter airliner or feeder liner is a small airliner that is designed to fly up to 100 passengers on short-haul flights, usually feeding larger carriers' airline hubs from small markets. This class of airliners is typically flown by the regional airlines that are either contracted by or subsidiaries of the larger airlines. Regional airliners are used for short trips between smaller towns or from a larger city to a smaller city. Feeder liner, commuter, and local service are all alternative terms for the same class of flight operations. History To keep short routes economical, airlines preferred using second hand aircraft than costlier new aircraft. Older aircraft were put into short haul service as they were replaced by new longer-range designs. Post-war era Propeller aircraft of larger airlines were transferred to smaller airlines. Examples included the De Havilland Dragon Rapide biplane and the Douglas DC-3s, in large surplus after the war, which the a ...

Turboprop
A turboprop is a Gas turbine, gas turbine engine that drives an aircraft Propeller (aeronautics), propeller. A turboprop consists of an intake, reduction drive, reduction gearbox, gas compressor, compressor, combustor, turbine, and a propelling nozzle. Air enters the intake and is compressed by the compressor. Fuel is then added to the compressed air in the combustor, where the Fuel mixture, fuel-air mixture then Combustion, combusts. The hot combustion gases expand through the turbine stages, generating power at the point of exhaust. Some of the power generated by the turbine is used to drive the compressor and electric generator. The gases are then exhausted from the turbine. In contrast to a turbojet or turbofan, the engine's exhaust gases do not provide enough power to create significant thrust, since almost all of the engine's power is used to drive the propeller. Technological aspects Exhaust thrust in a turboprop is sacrificed in favor of shaft power, which is obtaine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
