Messerschmitt Me 209
The first Messerschmitt Me 209 was a single-engine racing aircraft which was designed for and succeeded at breaking speed records. This Me 209 was a completely new aircraft whose designation was used by Messerschmitt as a propaganda tool. Although the aircraft was designed only to break speed records, it was hoped that its name would associate it with the Bf 109 already in combat service.Lepage 2009, p. 220. The designation ''Me 209'' was given for propaganda purposes to cause confusion with the Messerschmitt Bf 109, the ''Luftwaffe''s primary fighter throughout World War II. It was later reused for the actual proposed successor to the Bf 109. Design and development The designation Me 209 was used for two separate projects during World War II. The first was a record-setting, single-engined race aircraft, for which little or no consideration was given to adaptation for combat. The second Me 209 was a proposal for a follow-up to the highly successful Messerschmitt Bf 109 wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prototype
A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and Software prototyping, software programming. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. In some design workflow models, creating a prototype (a process sometimes called materialization) is the step between the Formal specification, formalization and the evaluation of an idea. A prototype can also mean a typical example of something such as in the use of the derivation 'prototypical'. This is a useful term in identifying objects, behaviours and concepts which are considered the accepted norm and is analogous with terms such as stereotypes and archetypes. The word ''wikt:prototype, prototype'' derives from the Greek language, Greek ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MG 17 Machine Gun
The MG 17 was a 7.92 mm machine gun produced by Rheinmetall-Borsig for use at fixed mountings in many World War II Luftwaffe aircraft, typically as forward-firing offensive armament. The MG 17 was based on the older MG 30 light machine gun, as was its defensive flexible-mount counterpart, the MG 15 machine gun. History A mainstay fixed machine gun in German built aircraft (many of which were sold to other countries) well before World War II, by 1940 it was starting to be replaced with heavier caliber machine gun and cannons. By 1945 very few if any aircraft mounted the MG 17. The MG 17 was installed in the Messerschmitt Bf 109, Messerschmitt Bf 110, Focke-Wulf Fw 190, Junkers Ju 87, Junkers Ju 88C Nightfighter, Heinkel He 111, Dornier Do 17/215 Nightfighter, Focke-Wulf Fw 189 and many other aircraft. Many MG 17s were later modified for infantry use, as the Luftwaffe replaced them with the heavier-calibre MG 131, which replaced both the MG 15 in bomber defense applicat ...

Synchronization Gear
A synchronization gear (also known as a gun synchronizer or interrupter gear) was a device enabling a single-engine tractor configuration aircraft to fire its forward-firing armament through the arc of its spinning propeller without bullets striking the blades. This allowed the aircraft, rather than the gun, to be aimed at the target. There were many practical problems, mostly arising from the inherently imprecise nature of an automatic gun's firing, the great (and varying) velocity of the blades of a spinning propeller, and the very high speed at which any gear synchronizing the two had to operate. In practice, all known gears worked on the principle of actively triggering each shot, in the manner of a semi-automatic weapon. Design and experimentation with gun synchronization had been underway in France and Germany in 1913–1914, following the ideas of August Euler, who seems to have been the first to suggest mounting a fixed armament firing in the direction of flight (in 191 ...

Supermarine Spitfire
The Supermarine Spitfire is a British single-seat fighter aircraft used by the Royal Air Force and other Allied countries before, during, and after World War II. Many variants of the Spitfire were built, from the Mk 1 to the Rolls-Royce Griffon engined Mk 24 using several wing configurations and guns. It was the only British fighter produced continuously throughout the war. The Spitfire remains popular among enthusiasts; around 70 remain airworthy, and many more are static exhibits in aviation museums throughout the world. The Spitfire was designed as a short-range, high-performance interceptor aircraft by R. J. Mitchell, chief designer at Supermarine Aviation Works, which operated as a subsidiary of Vickers-Armstrong from 1928. Mitchell developed the Spitfire's distinctive elliptical wing with innovative sunken rivets (designed by Beverley Shenstone) to have the thinnest possible cross-section, achieving a potential top speed greater than that of several contemporary figh ...

Battle Of Britain
The Battle of Britain, also known as the Air Battle for England (german: die Luftschlacht um England), was a military campaign of the Second World War, in which the Royal Air Force (RAF) and the Fleet Air Arm (FAA) of the Royal Navy defended the United Kingdom (UK) against large-scale attacks by Nazi Germany's air force, the Luftwaffe. It was the first major military campaign fought entirely by air forces."92 Squadron – Geoffrey Wellum." ''Battle of Britain Memorial Flight'' via ''raf.mod.uk.''. Retrieved: 17 November 2010, archived 2 March 2009. The British officially recognise the battle's duration as being from 10 July until 31 October 1940, which overlaps the period of large-scale night attacks known as |
Messerschmitt Me 163
The Messerschmitt Me 163 Komet is a rocket-powered interceptor aircraft primarily designed and produced by the German aircraft manufacturer Messerschmitt. It is the only operational rocket-powered fighter aircraft in history as well as the first piloted aircraft of any type to exceed in level flight. Development of what would become the Me 163 can be traced back to 1937 and the work of the German aeronautical engineer Alexander Lippisch and the ''Deutsche Forschungsanstalt für Segelflug'' (DFS). Initially an experimental programme that drew upon traditional glider designs while integrating various new innovations such as the rocket engine, the development ran into organisational issues until Lippisch and his team were transferred to Messerschmitt in January 1939. Plans for a propeller-powered intermediary aircraft were quickly dropped in favour of proceeding directly to rocket propulsion. On 1 September 1941, the prototype performed its maiden flight, where upon quickly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heini Dittmar
Heini Dittmar (Born March 30, 1912, Bad Kissingen, Unterfranken, Germany – Died April 28, 1960 near Mülheim an der Ruhr, West Germany) was a record-breaking German glider pilot. Inspired by the example of his glider flying brother Edgar, Dittmar took an apprenticeship at the German Institute for Gliding (DFS). In 1932, flying his self-built glider '' Kondor'', he won a first prize at the Rhön Glider Competition. Dittmar then became a research pilot. In 1934, he, Hanna Reitsch, Peter Riedel, and Wolf Hirth were members of Professor Georgii's South American Glider Expedition,Reitsch, H., 1955, The Sky My Kingdom, London: Biddles Limited, Guildford and King's Lynn, where in Argentina he achieved a new world gliding altitude record (about ). Later the same year, he achieved a new world record for long-distance using a '' Fafnir II'' and was awarded the Hindenburg Cup. In 1936, he achieved the first crossing of the Alps in a glider. He then crowned his career as a glider pilot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Air And Space Museum
The National Air and Space Museum of the Smithsonian Institution, also called the Air and Space Museum, is a museum in Washington, D.C., in the United States. Established in 1946 as the National Air Museum, it opened its main building on the National Mall near L'Enfant Plaza in 1976. In 2018, the museum saw about 6.2 million visitors, making it the fifth-most-visited museum in the world, and the second-most-visited museum in the United States. In 2020, due to long closures and a drop in foreign tourism caused by the COVID-19 pandemic, museum attendance dropped to 267,000. The National Air and Space Museum is a center for research into the history and science of aviation and spaceflight, as well as planetary science and terrestrial geology and geophysics. Almost all spacecraft and aircraft on display are originals or the original backup craft. The museum contains the Apollo 11 Command Module ''Columbia'', the ''Friendship 7'' capsule which was flown by John Glenn, Charles Lin ...

Grumman F8F Bearcat
The Grumman F8F Bearcat is an American single-engine carrier-based fighter aircraft introduced in late World War II. It served during the mid-20th century in the United States Navy, the United States Marine Corps, and the air forces of other nations. It was Grumman Aircraft's last piston engined fighter aircraft. Modified versions of the Bearcat have broken speed records for piston-engined aircraft. Today, the Bearcat is popular among warbird owners and air racers. Design and development Concept The Bearcat concept began during a meeting between Battle of Midway veteran F4F Wildcat pilots and Grumman Vice President Jake Swirbul at Pearl Harbor on 23 June 1942. At the meeting, Lieutenant Commander Jimmie Thach emphasized one of the most important requirements in a good fighter plane was "climb rate". Climb performance is strongly related to the power-to-weight ratio, and is maximized by wrapping the smallest and lightest possible airframe around the most powerful availab ...

Darryl Greenamyer
Darryl George Greenamyer (August 13, 1936 – October 4, 2018) was an American aviator. He started his flying career in the US Air Force Reserve. After leaving the Air Force, he then began to work at Lockheed where he eventually became an SR-71 test pilot at Skunk works. While working at Lockheed he met many of the engineers who would later help him make modifications to future race planes. He won his first victory in the Unlimited Class at the Reno Air Races in 1965. He is the third most successful competitor in Reno Air Race history. History On August 16, 1969, flying the highly modified Grumman F8F-2 Bearcat "Conquest I" (N1111L), Greenamyer broke the 30-year-old FAI Class C-1 Group I 3 km speed record with a speed of . An earlier attempt in 1966 by Greenamyer had to be aborted due to directional stability problems and an attempt in 1968 ended with a blown piston. The previous record had been set by Fritz Wendel flying a German Messerschmitt Me 209 in 1939. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
