Honeywell’s new HTS7500 turboshaft engine has been selected to power the coaxial/compound rotor Lockheed Martin Sikorsky-Boeing Defiant X, one of two finalists in the U.S. Army's Future Long-Range Assault Aircraft (FLRAA) competition. "This engine builds upon the battle-proven architecture of the T55 [that powers the Boeing H-47 Chinook], but the HTS7500 takes engine performance, reliability, and efficiency to a whole new level," said Honeywell Aerospace president of engines and power systems Dave Marinick.
