 The propulsion team for the Lockheed Martin JSF completed all engine testing associated with the development and flight qualification of the JSF119-611 engine for two JSF concept demonstrator aircraft, the X-35A and the X-35C. “Engine qualification has historically been the
pacing item for the first flight in new aircraft demonstration programs,” said Frank J. Cappuccio, vice president and program manager for the Lockheed Martin JSF. “Pratt & Whitney and the rest of the propulsion team have done a superb job in getting the engine ready ahead of our need date.” The final segment of the testing, the high-cycle fatigue and accelerated mission, was conducted at sea-level conditions at Pratt & Whitney in West Palm Beach, Florida. During the fatigue testing, the engine was subjected to more than double the operating time/events expected during the demonstrator flight program: 193 hours of operating time, 460 total accumulated cycles, seventeen hours of augmentor time, and 680 augmentor lights from various power settings. The remaining tasks for engine flight certification are engine tear-down, inspection, and data reviews.
