Westinghouse J40
The Westinghouse J40 was an early high-performance afterburning turbojet engine designed by Westinghouse Aviation Gas Turbine Division starting in 1946 to a US Navy Bureau of Aeronautics (BuAer) request. BuAer intended to use the design in several fighter aircraft and a bomber. However, while an early low-power design was successful, attempts to scale it up to its full design power failed, and the design was finally abandoned, deemed a "fiasco" and a "flop". The design originally called for an engine of thrust at sea level static conditions without afterburner and 10,900 lbf thrust with afterburner. A more powerful model 9,500/13,700 lbf thrust version was intended to replace the earlier engines in the various airframes. In total, thirteen different variations were planned. The projected need for the higher-power engines led BuAer to place a second source production contract with Ford Motor Company, Lincoln Mercury Division for both J40-WE-10 and J40-WE-12 engines.

Turbojet
The turbojet is an airbreathing jet engine which is typically used in aircraft. It consists of a gas turbine with a propelling nozzle. The gas turbine has an air inlet which includes inlet guide vanes, a compressor, a combustion chamber, and a turbine (that drives the compressor). The compressed air from the compressor is heated by burning fuel in the combustion chamber and then allowed to expand through the turbine. The turbine exhaust is then expanded in the propelling nozzle where it is accelerated to high speed to provide thrust. Two engineers, Frank Whittle in the United Kingdom and Hans von Ohain in Germany, developed the concept independently into practical engines during the late 1930s. Turbojets have poor efficiency at low vehicle speeds, which limits their usefulness in vehicles other than aircraft. Turbojet engines have been used in isolated cases to power vehicles other than aircraft, typically for attempts on land speed records. Where vehicles are "turbine-powere ...

General Electric
General Electric Company (GE) is an American multinational conglomerate founded in 1892, and incorporated in New York state and headquartered in Boston. The company operated in sectors including healthcare, aviation, power, renewable energy, digital industry, additive manufacturing and venture capital and finance, but has since divested from several areas, now primarily consisting of the first four segments. In 2020, GE ranked among the Fortune 500 as the 33rd largest firm in the United States by gross revenue. In 2011, GE ranked among the Fortune 20 as the 14th most profitable company, but later very severely underperformed the market (by about 75%) as its profitability collapsed. Two employees of GE – Irving Langmuir (1932) and Ivar Giaever (1973) – have been awarded the Nobel Prize. On November 9, 2021, the company announced it would divide itself into three investment-grade public companies. On July 18, 2022, GE unveiled the brand names of the companies it will ...

Combustor
A combustor is a component or area of a gas turbine, ramjet, or scramjet engine where combustion takes place. It is also known as a burner, combustion chamber or flame holder. In a gas turbine engine, the ''combustor'' or combustion chamber is fed high-pressure air by the compression system. The combustor then heats this air at constant pressure as the fuel/air mix burns. As it burns the fuel/air mix heats and rapidly expands. The burned mix is exhausted from the combustor through the nozzle guide vanes to the turbine. In the case of a ramjet or scramjet engines, the exhaust is directly fed out through the nozzle. A combustor must contain and maintain stable combustion despite very high air flow rates. To do so combustors are carefully designed to first mix and ignite the air and fuel, and then mix in more air to complete the combustion process. Early gas turbine engines used a single chamber known as a can-type combustor. Today three main configurations exist: can, annular, and c ...

Grumman XF10F-1 Jaguar
The Grumman XF10F Jaguar was a prototype swing-wing fighter aircraft offered to the United States Navy in the early 1950s. Although it never entered service, its research paved the way toward the later General Dynamics F-111 and Grumman's own F-14 Tomcat. Design and development The Navy's interest in the variable-geometry wing was based on concerns that the ever-increasing weight of its jet fighters was making aircraft carrier operations troublesome. Many of its existing aircraft already had marginal carrier performance, and the trend in weight growth was obviously upward. At the same time, the demands for high-speed performance demanded swept wing layouts that did not lend themselves to good takeoff characteristics. The prospect of combining the two in a single aircraft was enticing. Originally conceived as a swept-wing version of the earlier F9F Panther, in February–March 1948, the design was reconfigured with a T-tail and ultimately a variable-geometry wing.Winchester 2005, ...

Douglas XF4D-1 Skyray
The Douglas F4D Skyray (later redesignated F-6 Skyray) is an American carrier-based fighter/interceptor built by the Douglas Aircraft Company. Although it was in service for a relatively short time (1956–1964) and never entered combat, it was the first carrier-launched aircraft to hold the world's absolute speed record, at 752.943 mph,Angelluci 1987, p. 92. (1211.744 km/h) and was the first United States Navy and United States Marine Corps fighter that could exceed Mach 1 in level flight.Francillon 1979, p. 480. It was the last fighter produced by the Douglas Aircraft Company before it merged with McDonnell Aircraft and became McDonnell Douglas. The F5D Skylancer was an advanced development of the F4D Skyray that did not go into service. Design and development The Skyray was designed to meet a Navy requirement issued in 1947 for a fighter aircraft that could intercept and destroy an enemy aircraft at an altitude of 50,000 ft (15,240 m) within five minute ...

Douglas XA3D-1 Skywarrior
The Douglas A-3 Skywarrior is a jet-powered strategic bomber that was developed and produced by the Douglas Aircraft Company. It was designed by Douglas on behalf of the United States Navy, which sought a carrier-capable strategic bomber. During July 1949, Douglas was awarded the contract to produce its design, having bested eight other aircraft companies' submissions. Unlike rival designs, which had aimed for a maximum take-off weight, the Skywarrior was developed for a take-off weight, facilitating its use from the navy's existing s. Large portions of the aircraft were produced by the Westinghouse Electric Corporation, including its early Westinghouse J40 turbojet engines, which failed to meet promises and were replaced by the rival Pratt & Whitney J57 engine by mid-1953. On 28 October 1952, the prototype ''XA3D-1'' performed the type's maiden flight. On 31 March 1956, the Skywarrior entered squadron service with the Navy. Initially used in the nuclear-armed strategic bombe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North American X-10
The North American X-10 (originally designated RTV-A-5) was an unmanned technology demonstrator developed by North American Aviation. It was a subscale reusable design that included many of the design features of the SM-64 Navaho missile. The X-10 was similar to the development of the Bell X-9 Shrike project, which was based on features of the GAM-63 RASCAL. Development To facilitate development of the long-range Navaho surface-to-surface cruise missile, North American Aviation (NAA) developed the RTV-A-5 (Research Test Vehicle, Air Force), or X-10 in 1951. This vehicle was to prove critical flight technology for the design of the Navaho cruise missile. These included proving the basic aerodynamics to Mach 2, flight testing the inertial guidance unit and flight control avionics to the same speed, and validate the recovery system for the next phase in the Navaho program. Preliminary design of the X-10 was completed in February 1951 and the first vehicle was delivered to Edw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
