De Havilland Propellers
de Havilland Propellers was established in 1935, as a division of the de Havilland Aircraft company when that company acquired a licence from the Hamilton Standard company of America for the manufacture of variable-pitch propellers at a cost of about £20,000. Licence negotiations were completed in June 1934. At the same time an extensive new factory, claimed to be one of the largest in the world, was laid down at Lostock, Bolton, some distance away from de Havilland's main aircraft plant at Hatfield. This factory was built in only nine months as part of the government's emergency pre-war shadow-factory programme. de Havilland Propellers, Ltd., was incorporated on 27 April 1946, with the main headquarters at Hatfield as the centre of design, development, and flight-testing, but with the main production plant still at Lostock in Lancashire. Work on missiles began in the late 1940s, early 1950s at the Hatfield plant in facilities which had been used during the war for the de ...

Aircraft
An aircraft ( aircraft) is a vehicle that is able to flight, fly by gaining support from the Atmosphere of Earth, air. It counters the force of gravity by using either Buoyancy, static lift or the Lift (force), dynamic lift of an airfoil, or, in a few cases, direct Powered lift, downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), Glider (aircraft), gliders, Powered paragliding, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Aircrew, Crewed aircraft are flown by an onboard Aircraft pilot, pilot, whereas unmanned aerial vehicles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fibre-reinforced Plastic
Fibre-reinforced plastic (FRP; also called fibre-reinforced polymer, or in American English ''fiber'') is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass (in fibreglass), carbon (in carbon-fibre-reinforced polymer), aramid, or basalt. Rarely, other fibres such as paper, wood, boron, or asbestos have been used. The polymer is usually an epoxy, vinyl ester, or polyester thermosetting plastic, though phenol formaldehyde resins are still in use. FRPs are commonly used in the aerospace, automotive, marine, and construction industries. They are commonly found in ballistic armour and cylinders for self-contained breathing apparatuses. History Bakelite was the first fibre-reinforced plastic. Leo Baekeland had originally set out to find a replacement for shellac (made from the excretion of lac bugs). Chemists had begun to recognize that many natural resins and fibres were polymers, and Baekeland investigated the reactions of phenol an ...

Convair
Convair, previously Consolidated Vultee Aircraft Corporation, was an American aircraft-manufacturing company that later expanded into rockets and spacecraft. The company was formed in 1943 by the merger of Consolidated Aircraft and Vultee Aircraft. In 1953, it was purchased by General Dynamics, and operated as their Convair Division for most of its corporate history. Convair is best known for its military aircraft; it produced aircraft such as the Convair B-36 Peacemaker and Convair B-58 Hustler strategic bombers, and the Convair F-102 Delta Dagger and Convair F-106 Delta Dart interceptors. It also manufactured the first Atlas rockets, including the rockets that were used for the crewed orbital flights of Project Mercury. The company's subsequent Atlas-Centaur design continued this success and derivatives of the design remain in use as of 2025. The company also entered the jet airliner business with its Convair 880 and Convair 990 designs. These were smaller than conte ...

Blue Streak (missile)
The de Havilland Propellers Blue Streak was a British Intermediate-range ballistic missile (IRBM), and later the first stage of the Europa satellite launch vehicle. Blue Streak was cancelled without entering full production. The project was intended to maintain an independent British nuclear deterrent, replacing the V bomber fleet which would become obsolete by 1965. The operational requirement for the missile was issued in 1955 and the design was complete by 1957. During development, it became clear that the missile system was too expensive and too vulnerable to a surprise attack. The missile project was cancelled in 1960, with US-led Skybolt the preferred replacement. Partly to avoid political embarrassment from the cancellation, the UK government proposed that the rocket be used as the first stage of a civilian satellite launcher called Black Prince. As the cost was thought to be too great for the UK alone, international collaboration was sought. This led to the formati ...

The RAAF Woomera Range Complex (WRC) is a major Australian military and civil aerospace facility and operation located in South Australia, approximately north-west of Adelaide. The WRC is operated by the Royal Australian Air Force (RAAF), a Service of the Australian Defence Force (ADF). The complex has a land area of or roughly the size of North Korea or Pennsylvania.

Firestreak
The de Havilland Firestreak is a British first-generation, passive infrared homing (heat seeking) air-to-air missile. It was developed by de Havilland Propellers (later Hawker Siddeley) in the early 1950s, entering service in 1957. It was the first such weapon to enter active service with the Royal Air Force (RAF) and Fleet Air Arm, equipping the English Electric Lightning, de Havilland Sea Vixen and Gloster Javelin. It was a rear-aspect, fire and forget pursuit weapon, with a field of attack of 20 degrees either side of the target.Gibson 2007, p. 33 Developed under the rainbow code "Blue Jay", Firestreak was the third heat-seeking missile to enter service, after the US AIM-4 Falcon and AIM-9 Sidewinder, both of which entered service the previous year. In comparison to those designs, the Firestreak was larger and almost twice as heavy, carrying a much larger warhead. It had otherwise similar performance in terms of speed and range. It was also a very complex system, with an unus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ministry Of Supply
The Ministry of Supply (MoS) was a department of the UK government formed on 1 August 1939 by the Ministry of Supply Act 1939 ( 2 & 3 Geo. 6. c. 38) to co-ordinate the supply of equipment to all three British armed forces, headed by the Minister of Supply. A separate ministry, however, was responsible for aircraft production, and the Admiralty retained responsibilities for supplying the Royal Navy.Hornby (1958) During the war years the MoS was based at Shell Mex House in The Strand, London. The Ministry of Supply also took over all army research establishments in 1939. The Ministry of Aircraft Production was abolished in 1946, and the MoS took over its responsibilities for aircraft, including the associated research establishments. In the same year, it also took on increased responsibilities for atomic weapons, including the H-bomb development programme. The Ministry of Supply was abolished in late 1959 and its responsibilities passed to the Ministry of Aviation, the War Of ...
