Napier Scorpion
The Napier Scorpion series of rocket engines are a family of British liquid-fuelled engines that were developed and manufactured by Napier at the Napier Flight Development Establishment, Luton, in the late 1950s. The Scorpion range were designed and flight tested as boosters to improve aircraft take-off performance. Design and development After World War II the Air Ministry issued specifications for a wide variety of rocket engines, both liquid and solid-fuelled. Napier responded with the design of a liquid-fuelled rocket which used catalysed hydrogen peroxide (H2O2), in the form of High-Test Peroxide (HTP) as oxidiser and Kerosene as fuel. The Scorpion was a regeneratively-cooled HTP (High Test Peroxide/Kerosene) bi-propellant rocket engine. Fuel and oxidiser were pumped by a single shaft turbo-pump driven by super-heated steam, generated by catalysing HTP. Engine starting was achieved by an electric pump supplying HTP to the turbo-pump decomposition chamber. Once started, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bristol Siddeley Gamma
The Armstrong Siddeley, later Bristol Siddeley Gamma was a family of rocket engines used in British rocketry, including the Black Knight and Black Arrow launch vehicles. They burned kerosene fuel and hydrogen peroxide. Their construction was based on a common combustion chamber design, used either singly or in clusters of up to eight. They were developed by Armstrong Siddeley in Coventry, which later became Bristol Siddeley in 1959, and finally Rolls-Royce in 1966. Engine static testing was carried out at High Down Rocket Test Site, near The Needles on the Isle of Wight (). ( Spadeadam in Cumbria wasn't used for testing until Blue Streak, after Gamma). Advantages of kerosene / peroxide engines Use of kerosene / hydrogen peroxide engines has been a particularly British trait in rocket development, there being few comparable engines (such as the LR-40) from the USA. The combustion of kerosene with hydrogen peroxide is given by the formula : CH2 + 3H2O2 → CO2 + 4H2O where ... [...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 ...

Bristol Siddeley 605
The Bristol Siddeley BS.605 was a British take off assist rocket engine of the mid-1960s that used hydrogen peroxide and kerosene propellant. Design and development The BS.605 design was based on the smaller of two combustion chambers of the earlier Armstrong Siddeley Stentor. A pair of retractable BS.605 engines were fitted to Buccaneer S.50 strike aircraft of the South African Air Force for hot and high operations. The BS.605 was also considered for the Bluebird CMN-8, a design for a supersonic land speed record car, to be driven by Donald Campbell. Applications * Blackburn Buccaneer S.50 Engines on display *A complete BS.605 and exploded working parts of a second engine are on display at the Midland Air Museum. *A preserved BS.605 is part of the engine collection on display at the Royal Air Force Museum Cosford.

Liquid-propellant Rocket
A liquid-propellant rocket or liquid rocket utilizes a rocket engine that uses liquid propellants. Liquids are desirable because they have a reasonably high density and high specific impulse (''I''sp). This allows the volume of the propellant tanks to be relatively low. It is also possible to use lightweight centrifugal turbopumps to pump the rocket propellant from the tanks into the combustion chamber, which means that the propellants can be kept under low pressure. This permits the use of low-mass propellant tanks that do not need to resist the high pressures needed to store significant amounts of gasses, resulting in a low mass ratio for the rocket. An inert gas stored in a tank at a high pressure is sometimes used instead of pumps in simpler small engines to force the propellants into the combustion chamber. These engines may have a higher mass ratio, but are usually more reliable, and are therefore used widely in satellites for orbit maintenance. Liquid rockets can be m ...

Royal Air Force Museum London
The Royal Air Force Museum London (also commonly known as the RAF Museum) is located on the former Hendon Aerodrome. It includes five buildings and hangars showing the history of aviation and the Royal Air Force. It is part of the Royal Air Force Museum. There is another site at Royal Air Force Museum Cosford at RAF Cosford in Shropshire. History The Museum site at Colindale was once part of the RAF Hendon station and prior to that, one of the first civilian airfields, acquired by Claude Grahame-White in 1911. In 1914, the aerodrome was requisitioned for Home Defence during the First World War. Hendon became a Royal Naval Air Station, training new pilots in the flying schools on site. Operations ceased after the end of the Great War. From 1927 to 1939 Hendon housed No. 601 Squadron, nicknamed the 'Millionaires' Squadron' due to the wealth and upper social class of its volunteers. In 1939, the outbreak of war saw Hendon once again become an operational RAF station, home to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

English Electric Lightning
The English Electric Lightning is a British fighter aircraft that served as an interceptor during the 1960s, the 1970s and into the late 1980s. It was capable of a top speed of above Mach 2. The Lightning was designed, developed, and manufactured by English Electric, which was later merged into the newly-formed British Aircraft Corporation. Later the type was marketed as the BAC Lightning. It was operated by the Royal Air Force (RAF), the Kuwait Air Force (KAF), and the Royal Saudi Air Force (RSAF). A unique feature of the Lightning's design is the vertical, staggered configuration of its two Rolls-Royce Avon turbojet engines within the fuselage. The Lightning was designed and developed as an interceptor to defend the V bomber airfields from attack by anticipated future nuclear-armed supersonic Soviet bombers such as what emerged as the Tupolev Tu-22, but it was subsequently also required to intercept other bomber aircraft such as the Tupolev Tu-16 and the Tupolev Tu-9 ...
