F119 ENGINE

F119 AK 92

The F119-PW-100 turbofan is the only operational fifth generation fighter engine today, and is the most advanced production engine combining stealth technologies and vectored thrust with high thrust-to-weight performance to provide unprecedented maneuverability and survivability.

Two Pratt & Whitney F119 engines power the U.S Air Force’s F-22 Raptor. Supercruise, the ability to operate supersonically without afterburning, gives the F-22 exceptional combat performance without compromising mission range.

The F119 engine delivers unparalleled aircraft maneuverability with its unique two-dimensional pitch vectoring exhaust nozzle. This convergent/divergent nozzle vectors thrust as much as 20 degrees up or down. Nozzle position management is integrated with the F-22 flight control system and is automatically regulated by the Full-Authority Digital Electronic Control (FADEC), as are hundreds of other engine and aircraft operating parameters. The FADEC also features advanced diagnostics and on-condition management capability for maintenance awareness, autonomic logistics support and automatic field and test data processing.

The F119 is equipped with a number of advanced technologies for unmatched operational performance and reliability. Its three-stage integrally bladed fan is powered by a single-stage low-pressure turbine. The engine’s counterrotating core has an aerodynamically efficient six-stage compressor driven by a single-stage high-pressure turbine featuring the latest single-crystal superalloy blades and advanced cooling technologies. The robust, yet compact, high-pressure compressor features the most advanced airfoil aerodynamics and integrally bladed rotor disks for ensured durability.

On December 15, 2005, the U.S. Air Force declared the F-22 Raptor combat-ready, having achieved Initial Operational Capability (IOC) status. This milestone signified the F119-powered F-22 completed its development testing and was prepared to fly and fight in defense of the United States of America and its global interests. Just two years later, on December 12, 2007, the U.S Air Force declared Full Operational Capability (FOC) for the F-22.

The proven F119 is the forefather of the advanced F135 propulsion system, currently powering the F-35 Lightning II’s flight test program. To learn more about the F135 engine, click here.
