Handley Page Marathon
The Handley Page (Reading) H.P.R.1 Marathon was a British four-engined civil transport aircraft, capable of seating up to 20 passengers. It was designed by Miles Aircraft Limited and largely manufactured by Handley Page (Reading) Limited (who acquired Miles' assets) at Woodley Aerodrome Woodley is a town and civil parish in the Borough of Wokingham, in Berkshire, England. Woodley is east of Reading and adjoined to Earley which is to the west of the town and Woodley is from Wokingham. Nearby are the villages of Sonning, Tw ..., Reading, England. Originally submitted to the Air Ministry as a four-engined high-wing monoplane weighing roughly 16,500 lb, the concept was well received by the Brabazon Committee, with Miles being issued with instructions to proceed. While development proceeded, various agencies argued over the aircraft's specification, leading to multiple attempts to change the design midway though, delaying progress and inflating costs. Delays over the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handley Page
Handley Page Limited was a British aerospace manufacturer. Founded by Frederick Handley Page (later Sir Frederick) in 1909, it was the United Kingdom's first publicly traded aircraft manufacturing company. It went into voluntary liquidation and ceased to exist in 1970. The company, based at Radlett Aerodrome in Hertfordshire, was noted for its pioneering role in aviation history and for producing heavy bombers and large airliners. History Frederick Handley Page first experimented with and built several biplanes and monoplanes at premises in Woolwich, South Fambridge, Fambridge and Barking Creek. His company, founded on 17 June 1909, became the first British public company to build aircraft. In 1912, Handley Page established an aircraft factory at Cricklewood after moving from Barking, London, Barking. Aircraft were built there, and flown from the company's adjacent airfield known as Cricklewood Aerodrome, which was later used by Handley Page Transport. The factory was later ...

Rolls-Royce Dart
The Rolls-Royce RB.53 Dart is a turboprop engine designed and manufactured by Rolls-Royce Limited. First run in 1946, it powered the Vickers Viscount on its maiden flight in 1948. A flight on July 29 of that year, which carried 14 paying passengers between Northolt and Paris–Le Bourget Airport in a Dart-powered Viscount, was the first regularly scheduled airline flight by a turbine-powered aircraft.Turner 1968, p. 9. The Viscount was the first turboprop-powered aircraft to enter airline service - British European Airways (BEA) in 1953. The Dart was still in production forty years later when the last Fokker F27 Friendships and Hawker Siddeley HS 748s were produced in 1987. Following the company's convention for naming gas turbine engines after rivers, this turboprop engine design was named after the River Dart. History Designed in 1946 by a team led by Lionel Haworth, the Dart engine was derived using experience gained from the earlier more powerful Rolls-Royce Clyde t ...

Armstrong Siddeley Mamba
The Armstrong Siddeley Mamba was a British turboprop engine produced by Armstrong Siddeley in the late 1940s and 1950s, producing around 1,500 effective horsepower (1,100 kW). Armstrong Siddeley gas turbine engines were named after snakes. Design and development The Mamba was a compact engine with a 10-stage axial compressor, six combustion chambers and a two-stage power turbine. The epicyclic reduction gearbox was incorporated in the propeller spinner. Engine starting was by cartridge. The Ministry of Supply designation was ASMa (Armstrong Siddeley Mamba). The ASMa.3 gave 1,475 ehp and the ASMa.6 was rated at 1,770 ehp. A 500-hour test was undertaken in 1948 and the Mamba was the first turboprop engine to power the Douglas DC-3, when in 1949, a Dakota testbed was converted to take two Mambas. The Mamba was also developed into the form of the Double Mamba, which was used to power the Fairey Gannet anti-submarine aircraft for the Royal Navy. This was essentially two ...

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] |
