Pratt & Whitney F119
From Wikipedia, the free encyclopedia
The F119-PW-100 is an afterburning turbofan engine developed for the Lockheed Martin F-22 Raptor advanced tactical fighter by Pratt & Whitney.
The engine delivers thrust in the 35,000 lbf (160 kN) 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.[1] The F-119's nozzles incorporate thrust 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 the Lockheed Martin F-35, is a derivative engine of the F119. It has 40,000 lbf (180 kN) of thrust, the most ever in a fighter engine.[citation needed]
