Rolls-Royce Avon Mk.67
The Rolls-Royce Avon was the first axial flow jet engine designed and produced by Rolls-Royce Limited, Rolls-Royce. Introduced in 1950, the engine went on to become one of their most successful post-World War II engine designs. It was used in a wide variety of aircraft, both military and civilian, as well as versions for stationary and maritime power. An English Electric Canberra powered by two Avons made the first un-refuelled non-stop transatlantic flight by a jet, and a British Overseas Airways Corporation, BOAC de Havilland Comet, de Havilland Comet 4 powered by four Avons made the first scheduled transatlantic crossing by a jet airliner. Production of the Avon aero engine version ended after 24 years in 1974.Gunston 1989, p. 149. Production of the Avon-derived industrial version, currently produced by Siemens, continues to this day. The current version of the Avon, the Avon 200, is an industrial gas generator that is rated at . As of 2011, 1,200 Industrial Avons have bee ...

Transatlantic Flight
A transatlantic flight is the flight of an aircraft across the Atlantic Ocean from Europe, Africa, South Asia, or the Middle East to North America, Central America, or South America, or ''vice versa''. Such flights have been made by fixed-wing aircraft, airships, balloons and other aircraft. Early aircraft engines did not have the reliability nor the power to lift the required fuel to make a transatlantic flight. There were difficulties navigating over the featureless expanse of water for thousands of miles, and the weather, especially in the North Atlantic, is unpredictable. Since the middle of the 20th century, however, transatlantic flight has become routine, for commercial, military, diplomatic, and other purposes. History The idea of transatlantic flight came about with the advent of the hot air balloon. The balloons of the period were inflated with coal gas, a moderate lifting medium compared to hydrogen or helium, but with enough lift to use the winds that would later be ...

Armstrong-Siddeley Sapphire
The Armstrong Siddeley Sapphire is a British turbojet engine that was produced by Armstrong Siddeley in the 1950s. It was the ultimate development of work that had started as the Metrovick F.2 in 1940, evolving into an advanced axial flow design with an annular combustion chamber that developed over . It powered early versions of the Hawker Hunter and Handley Page Victor, and every Gloster Javelin. Production was also started under licence in the United States by Wright Aeronautical as the J65, powering a number of US designs. The Sapphire's primary competitor was the Rolls-Royce Avon. Design and development Design evolution of the Sapphire started at Metropolitan-Vickers (Metrovick) in 1943 as an offshoot of the F.2 project. With the F.2 reaching flight quality at about , Metrovick turned to producing larger designs, both an enlarged F.2 known as the ''Beryl'', as well as the much larger F.9 ''Sapphire''. (The names were chosen after a decision to use gemstones for future en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hucknall Airfield
Hucknall Aerodrome was a former general aviation and RAF aerodrome located north northwest of Nottingham, Nottinghamshire, England and west of Hucknall town. The aerodrome had been operated by the Merlin Flying Club since 1971, and then by Rolls-Royce Group plc. Before its closure, it was owned and operated by ITP Aero. Hucknall Aerodrome had a CAA Ordinary Licence (Number P507) that allowed daytime flights for the public transport of passengers or for flying instruction as authorised by the licensee and was not available for public transport passenger flights required to use a licensed aerodrome. It was a C.1916 grass aerodrome of significant historical importance. On 1 March 2015 the aerodrome closed indefinitely to be turned into a housing and industrial estate. History The Great War Hucknall Aerodrome dates to 1916 when it opened under No. 12 (Training) Group, 27th Wing, housing No. 15 Training Depot of the Royal Flying Corps (RFC) operating the Curtiss Jenny JN-4. ...

United Kingdom Military Aircraft Serials
United Kingdom military aircraft serial numbers are aircraft registration numbers used to identify individual military aircraft in the United Kingdom (UK). All UK military aircraft are allocated and display a unique registration number. A unified registration number system, maintained initially by the Air Ministry (AM), and its successor the Ministry of Defence (MoD), is used for aircraft operated by the Royal Air Force (RAF), Fleet Air Arm (FAA), and Army Air Corps (AAC). Military aircraft operated by government agencies and civilian contractors (for example QinetiQ) are also assigned registration numbers from this system. When the Royal Flying Corps (RFC) was formed in 1912, its aircraft were identified by a letter/number system related to the manufacturer. The prefix 'A' was allocated to balloons of No.1 Company, Air Battalion, Royal Engineers, the prefix 'B' to aeroplanes of No.2 Company, and the prefix 'F' to aeroplanes of the Central Flying School.Bruce 1956, p.922 ...

Avro Lancastrian
The Avro 691 Lancastrian was a Canadian and British passenger and mail transport aircraft of the 1940s and 1950s developed from the Avro Lancaster heavy bomber. The Lancaster was named after Lancaster, Lancashire; a Lancastrian is an inhabitant of Lancashire. The Lancastrian was basically a modified Lancaster bomber without armour or armament and with the gun turrets replaced by streamlined metal fairings, including a new nose section. The initial batch was converted directly from Lancasters; later batches were new builds. Design and development In 1943, Canada's Victory Aircraft converted a Lancaster X bomber for civilian transport duties with Trans-Canada Airlines (TCA). (After the war Victory Aircraft was purchased by what became Avro Canada). This conversion was a success, resulting in eight additional Lancaster Xs being converted. The "specials" were powered by Packard-built Merlin 38 engines and featured a lengthened, streamlined nose and tail cone. Range was incre ...

Bristol Aeroplane Company
The Bristol Aeroplane Company, originally the British and Colonial Aeroplane Company, was both one of the first and one of the most important British aviation companies, designing and manufacturing both airframes and aircraft engines. Notable aircraft produced by the company include the 'Boxkite', the Bristol Fighter, the Bulldog, the Blenheim, the Beaufighter, and the Britannia, and much of the preliminary work which led to Concorde was carried out by the company. In 1956 its major operations were split into Bristol Aircraft and Bristol Aero Engines. In 1959, Bristol Aircraft merged with several major British aircraft companies to form the British Aircraft Corporation (BAC) and Bristol Aero Engines merged with Armstrong Siddeley to form Bristol Siddeley. BAC went on to become a founding component of the nationalised British Aerospace, now BAE Systems. Bristol Siddeley was purchased by Rolls-Royce in 1966, who continued to develop and market Bristol-designed engines. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geoff Wilde
Geoffrey Light Wilde (21 May 1917 – 18 August 2007) was a British engineer employed by Rolls-Royce Limited. Early life Geoffrey Light Wilde was born in Warwickshire. He was first educated in France, where his father Alfred was working. His father died when he was 12. He would later move to Leamington and attend Warwick School. He was then apprenticed to the Daimler Company in Coventry. Later he gained an HNC in Mechanical Engineering from Coventry Technical College. Career Rolls-Royce In 1938 he joined Rolls-Royce Limited in Derby where he did much of the design work for their compressors. While working on test beds for the Merlin engines, he proposed a variable-speed supercharger, to increase the performance at altitude, that was subsequently incorporated in the Merlin XX. He helped Stanley Hooker to design and develop the Merlin two-stage supercharger used in the Merlin 60-series. Early jet engines were being developed at Lutterworth in Leicestershire, which were having ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stanley Hooker
Sir Stanley George Hooker, CBE, FRS, DPhil, BSc, FRAeS, MIMechE, FAAAS, (30 September 1907 – 24 May 1984) was a mathematician and jet engine engineer. He was employed first at Rolls-Royce where he worked on the earliest designs such as the Welland and Derwent, and later at Bristol Aero Engines where he helped bring the troubled Proteus turboprop and the Olympus turbojet to market.

Rolls-Royce Nene
The Rolls-Royce RB.41 Nene is a 1940s British centrifugal compressor turbojet engine. The Nene was a complete redesign, rather than a scaled-up Rolls-Royce Derwent"Rolls-Royce Aero Engines" Bill Gunston, Patrick Stephens Limited 1989, , p.111 with a design target of , making it the most powerful engine of its era. It was Rolls-Royce's third jet engine to enter production, and first ran less than 6 months from the start of design. It was named after the River Nene in keeping with the company's tradition of naming its jet engines after rivers. The design saw relatively little use in British aircraft designs, being passed over in favour of the axial-flow Avon that followed it. Its only widespread use in the UK was in the Hawker Sea Hawk and the Supermarine Attacker. In the US it was built under licence as the Pratt & Whitney J42, and it powered the Grumman F9F Panther. Its most widespread use was in the form of the Klimov VK-1, a reverse-engineered, modified and enlarged version w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alan Arnold Griffith
Alan Arnold Griffith (13 June 1893 – 13 October 1963), son of Victorian science fiction writer George Griffith, was an English engineer. Among many other contributions he is best known for his work on stress and fracture in metals that is now known as metal fatigue, as well as being one of the first to develop a strong theoretical basis for the jet engine. Griffith's advanced axial-flow turbojet engine designs, were integral in the creation of Britain's first operational axial-flow turbojet engine, the Metropolitan-Vickers F.2 which first ran successfully in 1941. Griffith however had little direct involvement in actually producing the engine, after he moved in 1939 from leading the engine department at the Royal Aircraft Establishment to start work at Rolls-Royce. Early work A. A. Griffith took a first in mechanical engineering, followed by a master's degree and a Doctorate from the University of Liverpool. In 1915 he was accepted by the Royal Aircraft Factory as a traine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
