Pratt & Whitney successfully completes testing on F135 engine with adaptive fan

Pratt & Whitney has successfully completed testing of an adaptive three-stream fan in an engine with an F135 core as part of the U.S. Air Force Research Laboratory’s Adaptive Engine Technology Development (AETD) program. Successful testing of the three-stream engine architecture demonstrates Pratt & Whitney is well positioned to transition adaptive engine technology to meet future U.S. Air Force requirements for combat aircraft propulsion. “Preliminary data from the test indicates our three-stream fan has met or exceeded expectations with respect to performance as well as the integrity of the turbofan machinery and fan module,” said Matthew Bromberg, president, Pratt & Whitney Military Engines. “This is an important milestone on the path toward the advancement and maturation of a next generation adaptive engine which will enable the warfighter to stay well ahead of future and emerging threats.”
