Hawker Typhoon
The Hawker Typhoon was a British single-seat fighter-bomber, produced by Hawker Aircraft. It was intended to be a medium-high altitude interceptor aircraft, interceptor, as a replacement for the Hawker Hurricane, but several design problems were encountered and it never completely satisfied this requirement.Thomas and Shores 1988, p. 16. The Typhoon was originally designed to mount twelve .303 British, .303 inch (7.7 mm) M1919 Browning machine gun, Browning machine guns and be powered by the latest engines. Its service introduction in mid-1941 was plagued with problems and for several months the aircraft faced a doubtful future. When the ''Luftwaffe'' brought the new Focke-Wulf Fw 190 into service in 1941, the Typhoon was the only RAF fighter capable of catching it at low altitudes; as a result it secured a new role as a low-altitude interceptor. The Typhoon became established in roles such as night-time intruder and long-range fighter. From late 1942 the Typhoon was equipped ...

RAF Colerne
Royal Air Force Colerne or more simply RAF Colerne is a former Royal Air Force station which was on the outskirts of the village of Colerne in Wiltshire, England, and was in use from 1939 to 1976. The site is now known as Azimghur Barracks and is home to 21 Signal Regiment, Royal Signals and 93 (City of Bath) Air Training Corps detached flight. History Second World War Originally there had been a farm called Doncombe and a vineyard on the site of the airfield, the names of Doncombe Lane and Doncombe Hill being the last link to the farm. From 1940 to 1955 RAF Fighter Command units were based here. During the Battle of Britain the airfield served as a satellite field to RAF Middle Wallop, and squadrons rotated back and forth from there on a daily basis. Later it was a training station for night fighter navigators. Using the latest night fighter procedures, the unit involved was No. 238 Operational Conversion Unit RAF from June 1952 until January 1957 and Bristol Brigand t ...

Ground-attack Aircraft
An attack aircraft, strike aircraft, or attack bomber is a tactical military aircraft that has a primary role of carrying out airstrikes with greater precision than bombers, and is prepared to encounter strong low-level air defenses while pressing the attack.Mortensen 1987, pp. 24–25. This class of aircraft is designed mostly for close air support and naval air-to-surface missions, overlapping the tactical bomber mission. Designs dedicated to non-naval roles are often known as ground-attack aircraft.Gunston 2009, p. 73. Fighter aircraft often carry out the attack role, although they would not be considered attack aircraft ''per se''; fighter-bomber conversions of those same aircraft would be considered part of the class. Strike fighters, which have effectively replaced the fighter-bomber and light bomber concepts, also differ little from the broad concept of an attack aircraft. The dedicated attack aircraft as a separate class existed primarily during and after World War ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monocoque
Monocoque ( ), also called structural skin, is a structural system in which loads are supported by an object's external skin, in a manner similar to an egg shell. The word ''monocoque'' is a French term for "single shell". First used for boats, a true monocoque carries both tensile and compressive forces within the skin and can be recognised by the absence of a load-carrying internal frame. Few metal aircraft other than those with milled skins can strictly be regarded as pure monocoques, as they use a metal shell or sheeting reinforced with frames riveted to the skin, but most wooden aircraft are described as monocoques, even though they also incorporate frames. By contrast, a semi-monocoque is a hybrid combining a tensile stressed skin and a compressive structure made up of longerons and ribs or frames. Other semi-monocoques, not to be confused with true monocoques, include vehicle unibodies, which tend to be composites, and inflatable shells or balloon tanks, both of whi ...

Duralumin
Duralumin (also called duraluminum, duraluminium, duralum, dural(l)ium, or dural) is a trade name for one of the earliest types of age hardening, age-hardenable aluminium–copper alloys. The term is a combination of ''Düren'' and ''aluminium'' . Its use as a trade name is obsolete. Today the term mainly refers to aluminium-copper alloys, designated as the 2000 series by the international alloy designation system (IADS), as with 2014 aluminium alloy, 2014 and 2024 aluminium alloy, 2024 alloys used in airframe fabrication. Duralumin was developed in 1909 in Germany. Duralumin is known for its strength and hardness, making it suitable for various applications, especially in the aviation and aerospace industry. However, it is susceptible to corrosion, which can be mitigated by using alclad-duralum materials. History Duralumin was developed by the German metallurgist Alfred Wilm at private military-industrial laboratory (Center for Scientific-Technical Research) in Neubabelsberg ...

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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supermarine
Supermarine was a British aircraft manufacturer. It is most famous for producing the Spitfire fighter plane during World War II. The company built a range of seaplanes and flying boats, winning the Schneider Trophy for seaplanes with three consecutive victories (in 1927, 1929 and 1931). After the war, the company produced a series of jet fighters. Overview Supermarine was founded in 1913 as Pemberton-Billing Ltd. The company was located on the River Itchen, Hampshire, River Itchen close to Woolston, Southampton, on ground purchased by the British aviator and inventor Noel Pemberton Billing to construct motor launches. Pemberton-Billing produced two prototype Multiplane_(aeronautics)#Quadruplanes, quadruplanes designed to shoot down Zeppelins—the Supermarine P.B.29 and the Supermarine Nighthawk. Both aircraft were fitted with the recoilless Davis gun. The Nighthawk had a separate Propulsion, powerplant to power a searchlight.The World's Worst Aircraft James Gilbert Pemberton-B ...

Supercharger
In an internal combustion engine, a supercharger compresses the intake gas, forcing more air into the engine in order to produce more power for a given displacement (engine), displacement. It is a form of forced induction that is mechanically powered (usually by a belt from the engine's crankshaft), as opposed to a turbocharger, which is powered by the kinetic energy of the exhaust gases. However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger. The first supercharged engine was built in 1878, with usage in aircraft engines beginning in the 1910s and usage in car engines beginning in the 1920s. In piston engines used by aircraft, supercharging was often used to compensate for the lower air density at high altitudes. Supercharging is less commonly used in the 21st century, as manufacturers have shifted to turbochargers to reduce fuel consumption and increase power outputs, especially with reduced engine dis ...

X Engine
An X engine is a piston engine with four banks of cylinders around a common crankshaft, such that the cylinders form an "X" shape when viewed front-on. The advantage of an X engine is that it is shorter than a V engine of the same number of cylinders, however the drawbacks are greater weight and complexity as compared to a radial engine. Therefore, the configuration has been rarely used. Several of the X engine designs were based on combining two V engines. Examples Four types of X engines are known to have reached production. In 1939–1942 Rolls-Royce Vulture, a X-24 aircraft engine which was built using two Rolls-Royce Peregrine V12 engines. The Rolls-Royce Vulture was briefly used in the Avro Manchester heavy bomber, before engine failures caused it to be replaced by the Avro Lancaster (powered by the Rolls-Royce Merlin V12 engine). General Motors also produced X engines for US naval ships during the Second World War. The 16-184 engine was installed in several hundred ...

H Engine
An H engine is a piston engine comprising two separate flat engine, flat engines (complete with separate crankshafts), most often geared to a common output shaft. The name "H engine" is due to the engine blocks resembling a letter "H" when viewed from the front. The most successful "H" engine in this form was the Napier Dagger and its derivatives. The name was also applied to engines of the same basic layout, but rotated through 90 degrees—most famously the Napier Sabre series. A variation on the "H" theme were the Fairey Prince (H-16) & Fairey Monarch, Fairey P.24 Monarch, where the two engines retained separate drives, driving Contra-rotating propellers through separate concentric shafts. Although successful, they only existed in prototype form. The H engine is a relatively rare layout, with its main use being in aircraft engines during the 1930s and 1940s. The 1966 Lotus 43 Formula One car used a BRM 16-cylinder H engine, and an 8-cylinder H engine was used for powerboat rac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cylinder (engine)
In an engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil. Steam engines The cylinder in a steam engine is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in cast iron and later in steel. The cylinder casting can include other features such as valve ports and mounting feet. Internal combustion engines The cylinder is the space through which the piston travels, propelled by the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an air-cooled e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolls-Royce Vulture
The Rolls-Royce Vulture was a British Aircraft engine, aero engine developed shortly before World War II that was designed and built by Rolls-Royce Limited. The Vulture used the unusual "X-24 engine, X-24" configuration, whereby four cylinder blocks derived from the Rolls-Royce Peregrine were joined by a common crankshaft supported by a single crankcase. The engine was originally designed to produce around but problems with the Vulture design meant that the engines were derated to around 1,450 to 1,550 hp in service by limiting the maximum Revolutions per minute, rpm. Although several new aircraft designs had been planned to use the Vulture, work on the engine's design ended in 1941 as Rolls-Royce concentrated on their more successful Rolls-Royce Merlin, Merlin design. Another 24-cylinder engine, the Napier Sabre, proved more successful after a lengthy development period.
