Pratt & Whitney Military Engines on Thursday delivered the 507th and last production F119
engine to the U.S. Air Force for its F-22 Raptor
fleet.
The F119 Final Engine Delivery ceremony at the Middletown, Conn. Engine Center was held with representatives from the Air Force, Lockheed Martin and Boeing in attendance.
"This is a bittersweet occasion for those of us who have played a part in 12 years of successful production deliveries," said Bennett Croswell, president of Military Engines at Pratt & Whitney."The F119 production engine program might be ending but we look forward to a 30-40 year sustainment period in partnership with the Air Force to keep the fleet flying."
The engine, considered one of the Air Force's most successful, is the forefather of the F135 propulsion system powering the F-35 Lightning II.
As Pratt & Whitney shifts from production to sustainment, the company has partnered with the U.S. Air Force at the Oklahoma City Air Logistics Center to manage scheduled overhauls of the F119 engine fleet.
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-22flight 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.
