The Pratt & Whitney F119, company designation PW5000, is an afterburning turbofan engine developed by Pratt & Whitney for the Advanced Tactical Fighter (ATF) program, which resulted in the Lockheed Martin F-22 Raptor. The engine delivers thrust in the 35,000 lbf (156 kN) class and was designed for sustained supersonic flight without ...
The Lockheed Martin/Boeing F-22 Raptor is an American twin-engine, all-weather, supersonic stealth fighter aircraft.As a product of the United States Air Force's Advanced Tactical Fighter (ATF) program, the aircraft was designed as an air superiority fighter, but also incorporates ground attack, electronic warfare, and signals intelligence capabilities.
The first production engines were delivered in 2009. [2] Developed from the Pratt & Whitney F119 engine used on the F-22 Raptor, the F135 produces around 28,000 lbf (125 kN) of thrust and 43,000 lbf (191 kN) with afterburner. [3] [4] The F135 competed with the General Electric/Rolls-Royce F136 to power the F-35.
Plans called for MANTA technologies to be demonstrated on either an F-22 Raptor or F-15. An X-44 prototype would begin test flights by fiscal year 2007. NASA planners stated that developing technologies for the X-44 could have application to the F-22 and Joint Strike Fighter programs and commercial supersonic ventures. [2]
Prototype engines were installed in the two competing technology demonstrator aircraft, the Lockheed YF-22 and Northrop YF-23. Pratt & Whitney's competing F119 was selected over the F120 to power the ATF, the competition for which the Lockheed team won, and became F-22 Raptor.
The 30-foot-wide Super Heavy first stage, loaded with 6.8 million pounds of liquid oxygen and methane propellants, stands 230 feet tall and is powered by 33 SpaceX-designed Raptor engines ...
The two Pratt & Whitney F119 that power the F-22 Raptor make it the most capable supercruise-capable fighter aircraft in service. The F-22 Raptor can supercruise above Mach 1.5 without external stores. [19] [20] [13] The EJ200 engine built by EuroJet Turbo GmbH mounted in the Eurofighter Typhoon.
Like the Newton, it was considered a commercial failure, primarily due to its astronomical price (almost $10,000!) and software issues. It was retired in 1986 and succeeded by the Macintosh.
