Rotating Detonation Engine (twz.com)
A novel type of jet propulsion, a rotating detonation engine (RDE), has been successfully tested by Pratt & Whitney. The development could be highly significant for the U.S. military, with RDE technology at the center of the project called Gambit, which aims to provide a propulsion system for a mass-producible, low-cost, high-supersonic, long-range weapon for air-to-ground strike.
