A Rotating Detonation Engine, RDE, is essentially a more compact and efficient method of creating thrust for a wide variety of military relevant systems. These mechanically simple engines have no moving parts making them less complex than gas turbine engines and therefore potentially lower cost and simpler to manufacture.

RDEs rapidly burn fuel via a supersonically travelling detonation wave; this in turn delivers high performance in a small volume. This volume savings can be used to increase fuel and/or payload volume providing potential range, speed, and affordability benefits compared to rockets, ramjets, and gas-turbines.

This rapidly developing technology enables a wide range of military applications including air-to-ground, air-to-air and surface weapons. Building on sustained Air Force and Navy investment, current research is targeted at expeditiously transitioning truly disruptive effects to the warfighter.
