Martin-Baker MB 3
The Martin-Baker MB 3 was a British prototype fighter aircraft, developed from Martin-Baker’s earlier private ventures, the MB 1 and the MB 2. The design was notable for its heavy armament of six 20 mm Hispano cannons. The fatal crash of the only prototype led to the cancellation of the programme. The design would carry over into a planned MB 4, but this cancelled in favour of a moderate re-design in the form of the MB 5. Design and development Using lessons learned from the MB 1 and MB 2, James Martin and Captain Valentine Baker capitalised in developing the design and construction to produce a new design, the MB 3, which was powered by a 2,000 hp Napier Sabre 24-cylinder, H-type engine, driving a de Havilland variable-pitch three-bladed propeller. The MB 3 was to meet an Air Ministry specification for a fighter. It was armed with six cannon mounted in the wings, each with 200 rounds of ammunition, which made it the most heavily-armed fighter in existen ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Flap (aeronautics)
A flap is a high-lift device used to reduce the stall (flight), stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in Drag (physics), drag so they are retracted when not needed. The flaps installed on most aircraft are partial-span flaps; spanwise from near the wing root to the inboard end of the ailerons. When partial-span flaps are extended they alter the spanwise lift distribution on the wing by causing the inboard half of the wing to supply an increased proportion of the lift, and the outboard half to supply a reduced proportion of the lift. Reducing the proportion of the lift supplied by the outboard half of the wing is accompanied by a reduction in the angle of attack on the outboard half. This is beneficial because it increases the margin above the Stall (fluid dynamics), stall of the outboa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawker Sea Fury
The Hawker Sea Fury is a British fighter aircraft designed and manufactured by Hawker Aircraft. It was the last propeller-driven fighter to serve with the Royal Navy, and one of the fastest production single reciprocating engine aircraft ever built. Developed during the Second World War, the Sea Fury entered service two years after the war ended. It proved to be a popular aircraft with a number of overseas militaries and was used during the Korean War in the early 1950s, and by the Cuban air force during the 1961 Bay of Pigs Invasion. The Sea Fury's development was formally initiated in 1943 in response to a wartime requirement of the Royal Air Force (RAF), with the aircraft initially named Fury. As the Second World War drew to a close, the RAF cancelled their order for the aircraft; however, the Royal Navy saw the type as a suitable carrier aircraft to replace a range of increasingly obsolete or poorly suited aircraft being operated by the Fleet Air Arm. Development of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CAC CA-15
The CAC CA-15, also known unofficially as the CAC Kangaroo, was an Australian propeller-driven fighter aircraft designed by the Commonwealth Aircraft Corporation (CAC) during World War II. Due to protracted development, the project was not completed until after the war, and was cancelled after flight testing, when the advent of jet aircraft was imminent. Design and development During 1943, following its success in rapidly designing and mass-producing the Boomerang fighter for the Royal Australian Air Force (RAAF), CAC began design work on a fully-fledged interceptor and escort fighter. Because the Boomerang had become more and more obsolete against Japanese fighters like the Mitsubishi A6M Zero, Sir Lawrence Wackett (as head of CAC) proposed designing a new high-performance fighter from scratch. Fred David, who had designed the Boomerang, was to lead an in-house design team at CAC. In June 1943, the design concept proposal was approved by the government and RAAF, which issued ...

Autocannon
An autocannon, automatic cannon or machine cannon is a fully automatic gun that is capable of rapid-firing large-caliber ( or more) armour-piercing, explosive or incendiary shells, as opposed to the smaller-caliber kinetic projectiles (bullets) fired by a machine gun. Autocannons have a longer effective range and greater terminal performance than machine guns, due to the use of larger/heavier munitions (most often in the range of , but bigger calibers also exist), but are usually smaller than tank guns, howitzers, field guns or other artillery. When used on its own, the word "autocannon" typically indicates a non-rotary weapon with a single barrel. When multiple rotating barrels are involved, such a weapon is referred to as a "rotary autocannon" or occasionally "rotary cannon", for short (particularly on aircraft). Autocannons are heavy weapons that are unsuitable for use by infantry. Due to the heavy weight and recoil Recoil (often called knockback, kickback o ...

Ejection Seat
In aircraft, an ejection seat or ejector seat is a system designed to rescue the aircraft pilot, pilot or other aircrew, crew of an aircraft (usually military) in an emergency. In most designs, the seat is propelled out of the aircraft by an explosive charge or rocket motor, carrying the pilot with it. The concept of an ejectable escape crew capsule has also been tried. Once clear of the aircraft, the ejection seat deploys a parachute. Ejection seats are common on certain types of military aircraft. History A bungee cord, bungee-assisted escape from an aircraft took place in 1910. In 1916, Everard Calthrop, an early inventor of parachutes, patented an ejector seat using compressed air. The modern layout for an ejection seat was first introduced by Romanian inventor Anastase Dragomir in the late 1920s. The design featured a ''parachuted cell'' (a dischargeable chair from an aircraft or other vehicle). It was successfully tested on 25 August 1929 at the Paris-Orly Airport ne ...

Rolls-Royce Griffon
The Rolls-Royce Griffon is a British 37-litre (2,240 cu in) capacity, 60-degree V-12, liquid-cooled aero engine designed and built by Rolls-Royce Limited. In keeping with company convention, the Griffon was named after a bird of prey, in this case the griffon vulture. Design work on the Griffon started in 1938 at the request of the Fleet Air Arm, for use in new aircraft designs such as the Fairey Firefly. In 1939 it was also decided that the engine could be adapted for use in the Spitfire. Development was stopped temporarily to concentrate efforts on the smaller Merlin and the 24-cylinder Vulture; the engine did not go into production until the early 1940s. The Griffon was the last in the line of V-12 aero engines to be produced by Rolls-Royce with production ceasing in 1955. Griffon engines remain in Royal Air Force service today with the Battle of Britain Memorial Flight and power the last remaining airworthy Avro Shackleton. Design and development Origins Accor ...
