EAST HARTFORD, Conn., JUNE 18, 2001 -- Pratt & Whitney successfully completed accelerated mission testing (AMT) of the F119-PW-100 propulsion system selected to power Lockheed Martin’s F/A-22 Raptor aircraft, further readying the engine for initial service release (ISR) approval and operational deployment.

The AMT, performed at the Air Force’s Arnold Engineering Development Center, simulated six to eight years of operational mission usage of the F/A-22 weapons system. The test included a total of 4,330 total accumulated cycles (TAC) and 834 hours of engine operation at sea level and simulated altitude conditions. Altitude testing, which included 400 simulated high mach number TAC cycles at high inlet pressure conditions, demonstrated engine performance and operability throughout the F/A-22’s anticipated flight envelope. In addition, the engine performed extensive high cycle fatigue testing to demonstrate the long-term durability of the F119 propulsion system hardware. It is currently being shipped to Pratt & Whitney’s Middletown, Conn., facility for disassembly and analytical condition inspection.

"The AMT not only demonstrated the F119 engine’s performance, reliability, and durability," said Tom Farmer, Vice President of F119/F/A-22 Engine Programs, Pratt & Whitney. "It also shows the expected low cost of operation of the engine through its ruggedness. This parallels the exceptional capabilities being demonstrated during the ongoing F/A-22 flight test evaluation program at Edwards Air Force Base. This engine is setting a new standard for readiness and performance, and we are proud to be a part of an exceptional Air Force and Lockheed Martin team."

To date, the F/A-22 flight test aircraft have accumulated more than 520 flights and 1,160 aircraft flight hours.

Pratt & Whitney, a United Technologies company (NYSE:UTX), is a world leader in the design, manufacture and service of aircraft engines, space propulsion systems and industrial gas turbines.
