- Pratt & Whitney F119
The F119-PW-100 is an afterburning
turbofan engine developed for theLockheed Martin F-22 Raptor advanced tactical fighter byPratt & Whitney .The engine delivers thrust in the convert|35000|lbf|kN|abbr=on thrust class (156 kN) and is designed for supersonic flight without the use of afterburner (
supercruise ). Delivering almost 22% more thrust with 40% fewer parts than conventional, fourth-generation military aircraft engine models, the F119 allows sustained supercruise speeds of up to Mach 1.72. [http://www.f22-raptor.com/technology/data.html F-22 Flight Test Data] . accessedAugust 8 2007 .] The F-119's nozzles incorporatethrust vectoring technology. These nozzles direct the engine thrust ±20° in the pitch axis to give the F-22A enhanced maneuverability. The F-22's maximum speed could possibly be close to Mach 2.5 but this is unlikely because of its airframe materials.The
Pratt & Whitney F135 , which powers theLockheed Martin F-35 , is a derivative engine of the F119.
