Jet Engines
A jet engine is a type of reaction engine, discharging a fast-moving jet (fluid), jet of heated gas (usually air) that generates thrust by jet propulsion. While this broad definition may include Rocket engine, rocket, Pump-jet, water jet, and hybrid propulsion, the term typically refers to an internal combustion airbreathing jet engine, air-breathing jet engine such as a turbojet, turbofan, ramjet, pulse jet engine, pulse jet, or scramjet. In general, jet engines are internal combustion engines. Air-breathing jet engines typically feature a Axial compressor, rotating air compressor powered by a turbine, with the leftover power providing thrust through the propelling nozzle—this process is known as the Brayton cycle, Brayton thermodynamic cycle. Jet aircraft use such engines for long-distance travel. Early jet aircraft used turbojet engines that were relatively inefficient for subsonic flight. Most modern subsonic jet aircraft use more complex High-bypass turbofan, high-bypas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pratt & Whitney F100
The Pratt & Whitney F100 (company designation JTF22) is a low bypass afterburner, afterburning turbofan engine. It was designed and manufactured by Pratt & Whitney to power the U.S. Air Force's "FX" initiative in 1965, which became the McDonnell Douglas F-15 Eagle, F-15 Eagle. The engine was to be developed in tandem with the Pratt & Whitney F401, F401 which shares a similar core but with an upscaled fan for the U.S. Navy's Grumman F-14 Tomcat, F-14 Tomcat. The F401 was later abandoned due to costs and reliability issues. The F100 also powered the General Dynamics F-16 Fighting Falcon, F-16 Fighting Falcon for the Air Force's Lightweight Fighter (LWF) program. Development In 1967, the United States Navy and United States Air Force issued a joint engine Request for Proposals (RFP) for the F-14 Tomcat and the FX, which became the parallel fighter design competition that led to the McDonnell Douglas F-15 Eagle, F-15 Eagle in 1970. This engine program was called the IEDP (Initial E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
