The engine delivers thrust in the 35,000 lbf (156 kN) class and was designed for sustained supersonic flight without afterburners, or supercruise. 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.
A jet engine is a type of reaction engine, discharging a fast-moving jet of heated gas (usually air) that generates thrust by jet propulsion. While this broad definition may include rocket , water jet , and hybrid propulsion, the term jet engine typically refers to an internal combustion air-breathing jet engine such as a turbojet , turbofan ...
Thrust vectoring nozzle of the F135-PW-600 STOVL variant Diagram of F-35B and smaller powered lift aircraft. Derived from the F119 engine, the F135 is a mixed-flow afterburning turbofan utilizing a similar core as the F119 with a new fan and LP turbine. [34] There are two F135 variants: the -100 and the -600 versions. [1]
A jet engine afterburner is an extended exhaust section containing extra fuel injectors. Since the jet engine upstream (i.e., before the turbine) will use little of the oxygen it ingests, additional fuel can be burned after the gas flow has left the turbines. When the afterburner is turned on, fuel is injected and igniters are fired.
A multi-axis thrust vectoring engine nozzle in motion. Thrust vectoring, also known as thrust vector control (TVC), is the ability of an aircraft, rocket or other vehicle to manipulate the direction of the thrust from its engine(s) or motor(s) to control the attitude or angular velocity of the vehicle.

An 80–93 kN (8,200–9,500 kgf; 18,000–21,000 lbf) thrust variant for single-engine light combat aircraft. [ 5 ] : 36 Proposed for an improved JAS-39 Gripen C military aircraft. [ 7 ] The M88-3 would have a new low pressure compressor (LPC) with a new variable stator vane stage and an increased mass flow of 73.4 kg/s (162 lb/s).
Derated thrust to 12,500 lbf (55.6 kN) dry and 16,850 lbf (75 kN) wet. [33] Proposed for international versions of the Korean T-50 series of trainers and fighter aircraft, but later superseded by a new offer with a standard F414. [8] [34] F414-G Produced for the Saab JAS 39 Gripen Demonstrator. Slightly modified for use in a single engine ...
The General Electric XA100 is an American adaptive cycle engine demonstrator being developed by General Electric (GE) for the Lockheed Martin F-35 Lightning II and forms the technological foundation for the company's XA102 propulsion system for the United States Air Force's sixth generation fighter program, the Next Generation Air Dominance (NGAD).
