Pratt & Whitney F119

rdfs:comment

In the 1980´s Pratt & Whitney developed the YF119 prototype engine, to meet the US Air Force ( and at this time Navy ) requirements, for the Advanced Tactical Fighter competition. The first time it was used in 1990 by the Lockheed Martin YF-22 and the Northtrop YF-23 competitor. To reduce maintenace for the engine 40 % fewer parts were used in comparison to at this time conventional engines. The F119 engine allows the F-22 Raptor to Supercruise, what means the F-22 is able to fly faster then the sound without use of Afterburner ( up to Mach 1.82 ), this results in to better fuel effectiveness and an increased combat radius. The engine was selected in 1991 for the F-22 Raptor, the winner of the Advanced Tactical Fighter competition.

The engine was selected in 1991 for the F-22 Raptor, the winner of the Advanced Tactical Fighter competition. The top thrust of the engine with full afterburner is known to be about 157 kN, but this is in realty much higher, how much is unknown, but probably much, because the top thrust is classified by the US Air Force.
