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.
Delivering almost 22% more thrust with 40% fewer parts than its F100 predecessor, the F119 allows the F-22 to achieve supercruise speeds of up to Mach 1.8. [ 1 ] [ 2 ] The F119's nozzles incorporate thrust vectoring that enable them to direct the engine thrust ±20° in the pitch axis to give the F-22 enhanced maneuverability.
The AN/APG-77 system itself exhibits a very low radar cross-section, supporting the F-22's stealthy design. [3] The upgraded APG-77(V)1 may have an even greater range. Much of the technology developed for the APG-77 was used in the AN/APG-81 radar for the F-35 Lightning II , and in turn the technology from the APG-81 was applied to the upgraded ...
In order to fly the F-22, Larson said he had to go through basic pilot training, consisting of 55 weeks of flying in trainer aircraft like the T-6 Texan II and a T-38 Talon.
The fixed-price approach would cover initial F136 engine production, beginning with the F136 second production lot. According to the GE Rolls-Royce Fighter Engine Team, the proposal would shift significant cost risk from taxpayers to the Fighter Engine Team until head-to-head competition begins between the F136 and the Pratt & Whitney F135 ...
The YF120-powered the YF-22 and YF-23 to supercruise speeds of Mach 1.58 and Mach 1.72 respectively. [6] [7] [N 1] The first YF-22 (right), registration number N22YF, was powered by two YF120 engines. The Engineering & Manufacturing Development (EMD) configuration of the F120 was tested in December 1990.
Taylorcraft F-21 [1] [3] The Taylorcraft F22 is a two-seat American light aircraft produced in small numbers by Taylorcraft in the late 1980s and early 1990s. [ 1 ] [ 3 ] It is a further development of the Taylorcraft F-19 via the F-21 design.
