Airacomet
The Bell P-59 Airacomet was a single-seat, twin jet-engine fighter aircraft that was designed and built by Bell Aircraft during World War II, the first produced in the United States. As the British were further along in jet engine development, they donated an engine for the United States to copy in 1941 that became the basis for the General Electric jet used by the P-59 a year later. Because the plane was underpowered, the United States Army Air Forces (USAAF) was not impressed by its performance and canceled half of the original order for 100 fighters, using the completed aircraft as trainers. The USAAF would instead go on to select the Lockheed P-80 Shooting Star as its first operational jet fighter. Although no P-59s entered combat, the aircraft paved the way for later generations of U.S. turbojet-powered aircraft. Design and development Major General Henry H. "Hap" Arnold became aware of the UK's jet program when he attended a taxiing demonstration of the Gloste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Electric I-A
The General Electric I-A was the first working jet engine in the United States, manufactured by General Electric (GE) and achieving its first run on April 18, 1942. The engine was the result of receiving an imported Power Jets W.1X that was flown to the US from Britain in 1941, and the I-A itself was based on the design of the improved Power Jets W.2B, the plans of which were also received. Like these designs, the I-A engine was also of Centrifugal compressor, centrifugal design. The I-A engine led directly to the first production US jet engine, the General Electric J31 which powered the first US jet aircraft, the Bell P-59 Airacomet, Bell XP-59A Airacomet. Design and development During the late 1930s/early 1940s, a small company in England, known as Power Jets, had been developing, through a series of prototypes, a gas turbine engine to provide aircraft jet propulsion. Power Jets had been started by a Frank Whittle, who had thought of the concept of a jet engine whilst he was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bell XP-59
The Bell XP-52 and subsequent XP-59 were World War II fighter aircraft design projects by the American Bell Aircraft Corporation. Both projects featured a twin-boom layout with a rear-mounted engine driving pusher contra-rotating propellers. When the XP-59 project was canceled the designation XP-59A was used as a cover for a secret jet fighter prototype, which would enter production as the P-59 Airacomet. XP-52 The XP-52 design was begun by the Bell Company in 1940, separate from the R-40C competition, under the Air Material Command designator MX-3. The short fuselage carried a piston engine in the rear, driving a pair of contra-rotating propellers in a pusher configuration. The wings were swept back at an angle of 20 degrees, with a horizontal stabilizer mounted behind the propeller on twin booms running back from the wings. The fuselage was unusually streamlined, being round and barrel-shaped, with the forward-located pilot's cockpit fully faired-in to its lines and the ...

Power Jets
Power Jets was a British company set up by Frank Whittle for the purpose of designing and manufacturing jet engines. The company was nationalised in 1944, and evolved into the National Gas Turbine Establishment. History Founded on 27 January 1936, the company consisted of Whittle, Rolf Dudley-Williams, James Collingwood Tinling, and Lancelot Law Whyte of investment bankers O T Falk & Partners. Initial premises were hired from British Thomson-Houston (BTH) at Rugby, Warwickshire. In addition to the founder members, the company initially 'borrowed' some fitters from BTH to assist in the project and later Power Jets was able to get 'one or two' people on loan from the Royal Air Force. By the beginning of 1940 the company had a total workforce of about twenty five. In 1938 Power Jets had moved from Rugby to BTH's works in Lutterworth. A major breakthrough for the company came in 1940 when at the prompting of Stanley Hooker, Ernest Hives, chairman of Rolls-Royce, visited Lutt ...

Bell Aircraft
The Bell Aircraft Corporation was an American aircraft manufacturer, a builder of several types of fighter aircraft for World War II but most famous for the Bell X-1, the first supersonic aircraft, and for the development and production of many important civilian and military helicopters. Bell also developed the Reaction Control System for the Mercury Spacecraft, North American X-15, and Bell Rocket Belt. The company was purchased in 1960 by Textron, and lives on as Bell Textron. History As a pilot, Larry Bell saw his first plane at an air show, starting a lifelong fascination with aviation. Bell dropped out of high school in 1912 to join his brother in the burgeoning aircraft industry at the Glenn L. Martin Company, where by 1914 he had become shop superintendent. By 1920, Bell was vice president and general manager of Martin, then based in Cleveland. Feeling that he deserved part ownership, in late 1924, he presented Martin with an ultimatum. Mr. Martin refused, and Bell q ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed P-80 Shooting Star
The Lockheed P-80 Shooting Star was the first Jet aircraft, jet fighter aircraft, fighter used operationally by the United States Army Air Forces (USAAF) during World War II. Designed and built by Lockheed Corporation, Lockheed in 1943 and delivered just 143 days from the start of design, production models were flying, and two pre-production models did see very limited service in Italy just before the end of World War II. Designed with straight wings, the type saw extensive combat in Korea with the United States Air Force (USAF) as the F-80. America's first successful turbojet-powered combat aircraft, it was soon outclassed with the appearance of the swept-wing transonic MiG-15 and was quickly replaced in the air superiority role by the transonic F-86 Sabre. The F-94 Starfire, an all-weather interceptor using the same airframe, also saw Korean War service. The closely related Lockheed T-33, T-33 Shooting Star Trainer (aircraft), trainer remained in service with the U.S. Air For ...

United States Army Air Forces
The United States Army Air Forces (USAAF or AAF) was the major land-based aerial warfare service component of the United States Army and ''de facto'' aerial warfare service branch of the United States during and immediately after World War II (1941–1945). It was created on 20 June 1941 as successor to the previous United States Army Air Corps and is the direct predecessor of the United States Air Force, today one of the six United States Armed Forces, armed forces of the United States. The AAF was a component of the United States Army, which on 2 March 1942 was divided functionally by executive order into three autonomous forces: the Army Ground Forces, the United States Army Services of Supply (which in 1943 became the Army Service Forces), and the Army Air Forces. Each of these forces had a commanding general who reported directly to the Chief of Staff of the United States Army, Army Chief of Staff. The AAF administered all parts of military aviation formerly distributed am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lawrence Dale Bell
Lawrence Dale "Larry" Bell (April 5, 1894 – October 20, 1956) was an American industrialist and founder of Bell Aircraft Corporation. Biography Bell was born in Mentone, Indiana, and lived there until 1907, when his family moved to Santa Monica, California. He joined his older brother Grover and stunt pilot Lincoln Beachey as a mechanic in 1912. Grover Bell was killed in a plane crash the following year, and Lawrence vowed to quit aviation for good; however, he went to work for the Glenn L.

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] |
Disinformation
Disinformation is false information deliberately spread to deceive people. It is sometimes confused with misinformation, which is false information but is not deliberate. The English word ''disinformation'' comes from the application of the Latin prefix ''dis-'' to ''information'' making the meaning "reversal or removal of information". The rarely used word had appeared with this usage in print at least as far back as 1887. Some consider it a loan translation of the Russian ''dezinformatsiya'', derived from the title of a KGB black propaganda department. Defector Ion Mihai Pacepa claimed Joseph Stalin coined the term, giving it a French-sounding name to claim it had a Western origin. Russian use began with a "special disinformation office" in 1923. Disinformation was defined in '' Great Soviet Encyclopedia'' (1952) as "false information with the intention to deceive public opinion". Operation INFEKTION was a Soviet disinformation campaign to influence opinion that the U. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
