Pratt & Whitney is rebuilding an F135 Joint Strike Fighter engine that was damaged earlier this month during ground testing of the short take-off and landing propulsion system.
The F135 was damaged when a deliberate "hard stall" of the shaft-driven lift fan caused the driveshaft to break and debris was ingested by the engine, says Bill Gostic, P&W vice-president, F135 programmes.
The propulsion system was being tested with a mock-up of the lift-fan inlet planned for the STOVL version of the Lockheed Martin F-35, to check the airflow around the open inlet door while in the hover.
