De Havilland Engine Company
The de Havilland Engine Company was an offshoot of the de Havilland aircraft building company, which started life as the 'Engine Division of the de Havilland Aircraft Company' in 1926 producing the famous de Havilland Gipsy aero-engine. The company was merged with Bristol Siddeley (BSEL) engines in 1961 with BSEL subsequently becoming part of Rolls-Royce Limited in 1968. History The company was officially formed at Stag Lane Aerodrome, Stag Lane in February 1944 and later moved into a factory leased by the government in 1946 at Leavesden, Hertfordshire, Leavesden, which had earlier been a site for Handley Page Halifax production.Lumsden 2003, p.136. This is now the location of Leavesden Film Studios. It went on to produce one of the early turbojet engines the de Havilland Goblin which saw service in the early post-war de Havilland Vampire fighter. The later de Havilland Ghost, Ghost turbojet propelled early versions of the de Havilland Comet jetliner and the de Havilland Venom ...

Bristol Siddeley
Bristol Siddeley Engines Ltd (BSEL) was a British aero engine manufacturer. The company was formed in 1959 by a merger of Bristol Aero-Engines Limited and Armstrong Siddeley Motors Limited. In 1961 the company was expanded by the purchase of the de Havilland Engine Company and the engine division of Blackburn Aircraft. Bristol Siddeley was purchased by Rolls-Royce Limited in 1966. History Bristol Siddeley Engines Limited was formed by the 1 April 1959 merge of Bristol Aero-Engines and Armstrong Siddeley Motors. These were the aero engine manufacturing companies of the Bristol Aeroplane Company and the Hawker Siddeley Group. The share capital of Bristol Siddeley was held in equal proportions by these two parent organisations. At around the same time Bristol's aircraft manufacturing was being subsumed into the British Aircraft Corporation along with those of English Electric and Vickers-Armstrong. Armstrong Siddeley Motors had been producing aero-engines and motor-cars s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Electric T58
The General Electric T58 is an American turboshaft engine developed for helicopter use. First run in 1955, it remained in production until 1984, by which time some 6,300 units had been built. On July 1, 1959, it became the first turbine engine to gain FAA certification for civil helicopter use. The engine was license-built and further developed by de Havilland in the UK as the Gnome, in the West Germany by Klöckner-Humboldt-Deutz, and also manufactured by Alfa Romeo and the IHI Corporation. Design and development Development commenced with a 1953 US Navy requirement for a helicopter turboshaft to weigh under 400 lb (180 kg) while delivering 800 hp (600 kW). The engine General Electric eventually built weighed only 250 lb (110 kg) and delivered 1,050 hp (780 kW) and was soon ordered into production. First flight was on a modified Sikorsky HSS-1 in 1957, and civil certification for the CT58-100 variant was obtained two years later. A num ...

De Havilland Aircraft Museum
The de Havilland Aircraft Museum, formerly the de Havilland Aircraft Heritage Centre, is a volunteer-run aviation museum in London Colney, Hertfordshire, England. The collection is built around the definitive prototype and restoration shops for the de Havilland Mosquito and also includes several examples of the de Havilland Vampire – the third operational jet aircraft in the world. The museum is the largest such museum devoted to one manufacturer in the country. History Salisbury Hall The site has been occupied by a number of large manor houses since the 9th Century. The present house was built around 1668 by the London banker James Hoare, bringing with it associations with Charles II and Nell Gwynne, who lived in a cottage by the bridge to the Hall. The Hall subsequently passed through various hands, and during the latter part of the 19th century was occupied by a succession of farmers. However, about 1905 Lady Randolph Churchill, as Mrs. Cornwallis West, came here ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Havilland Spectre
The de Havilland Spectre is a rocket engine that was built by the de Havilland Engine Company in the 1950s. It was one element of the intended mixed power-plant for combination rocket-jet interceptor aircraft of the Royal Air Force, such as the Saunders-Roe SR.177. Design and development The Spectre was a bipropellant engine burning kerosene and hydrogen peroxide. The power could be controlled from 10–100% delivering 8,000 lbf (35.7 kN) of thrust at full power. In the SR.53 it used the same fuel tanks as the turbojet engine and if run at full power was expected to consume the full load in about seven minutes. In 1952 static testing commenced with the Spectre DSpe.l. The aircraft industry had no precedent for an engine which would gain in thrust with altitude and the required maximum thrust was estimated at between and thrust. The design was based on a variable thrust which could be throttled from to . Design philosophy was matched to the mixed power concept of an ...

De Havilland Sprite
The de Havilland Sprite is a British rocket engine that was built by de Havilland in the early-1950s for use in RATO (Rocket-assisted take off) applications. A developed engine with slightly less thrust but a longer burn time was known as the Super Sprite, production ceased in October 1960. Design and development For RATO use only a short burn time is required, with simplicity and light weight as major virtues. The intended market was for assisting take-off of de Havilland Comet 1 airliners (as hot and high operations in the British Empire were considered important) and also for V bombers carrying heavy nuclear weapons. 30 successful test flights were carried out by Comets, from May 1951, but gas turbine performance improved rapidly, and so RATO was not required in service. A hydrogen peroxide monopropellant was used, decomposed into oxygen and steam over a metallic calcium catalyst. The maximum thrust was , varying over the 16 second burn time for a total impulse of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
