The F119-PW-100 that powers Lockheed Martin's F-22 Raptor has completed accelerated mission testing (AMT), further readying the engine for initial service release (ISR), approval and operational deployment, says engine builder Pratt & Whitney.
The AMT simulated six to eight years of operational mission usage of the F-22 weapons system, including a 4,330 total accumulated cycles (TAC) and 834h of engine operation at sea level and simulated altitude conditions.
Altitude testing, including 400 simulated high mach number TAC cycles at high inlet pressure conditions, demonstrated engine performance and operability throughout the Raptor¹s 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.
To date, the F-22 flight test aircraft have accumulated more than 520 flights and 1,160 aircraft flight hours.
