Pratt & Whitney Scores Big with Cost-Saving F119 Deal
Pratt & Whitney, an RTX business, has secured a three-year contract worth up to USD 1.5 billion to sustain the F119 engines powering the U.S. Air Force’s F-22 fighter jets. The agreement aims to enhance fleet readiness and lower operational costs for more than 400 engines, which have collectively logged over 900,000 flight hours.
“The F119’s readiness and reliability rates have never been more important, and we are improving both while lowering lifecycle costs,” said Jill Albertelli, president of Military Engines at Pratt & Whitney. “We are committed to helping U.S. Air Force maintain the F-22’s combat edge.”
The F-22 Raptor’s two F119 engines generate over 35,000 pounds of thrust, enabling altitudes above 65,000 feet with amazing speed and agility. Unlike many fighter jets, the F-22 can sustain supersonic speeds without using afterburners — a strategic capability known as supercruise, which conserves fuel and extends its operational range.
Kinetic Performance
Pratt & Whitney has reduced costs on its F119 engines through its ongoing Usage Based Lifing programme, which uses real-time data to enhance maintenance efficiency and extend engine life. The company has also improved the engine’s kinematic performance with an updated engine control schedule.
The latest contract will continue these readiness and cost savings efforts with a focus on safety, availability, simplicity of maintenance, and modernisation initiatives.
Combat Performance
The F119-PW-100 turbofan is the first operational 5th Generation fighter engine. It combines stealth technologies and vectored thrust with high thrust-to-weight performance to provide unprecedented manoeuvrability and survivability.
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 advanced airfoil aerodynamics and integrally bladed rotor disks for ensured durability.
Supercruise, the ability to operate supersonically without afterburning, gives the F-22 exceptional combat performance without compromising mission range.
Aircraft Manoeuvrability
The F119 engine delivers unparalleled aircraft manoeuvrability 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.
Military Lineage
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 defence of the United States 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 F119 is the forefather of the advanced F135 propulsion system, which currently powers the 5th Generation F-35 Lightning II.
Building upon decades of combat-proven propulsion experience, the F135 is a marvel of modern engineering – from design and development to production and sustainment. From its adaptive and maintenance-friendly design to the use of exotic materials and advanced manufacturing processes, the F135 is the pinnacle of combat propulsion.
The capabilities of the F135 provide the warfighter with a critical advantage over adversaries and enables the F-35 to conduct operations in advanced anti-access/area denial (A2/AD) environments.
With its damage tolerant design and fully integrated prognostic health monitoring, the F135 has demonstrated exceptional mission capability rates since its first flight in 2006.
