The Rotating Detonation Engine being developed by Pratt & Whitney has no moving parts, which reduces complexity and costs, and could help enable high-speed, long-range flight with increased efficiency ...

At the U.S. Naval Research Laboratory, scientists are studying the complex physics of rotating detonation engines which offer the potential for high dollar savings by way of reduced fuel consumption ...

Pratt & Whitney has secured a US Air Force (USAF) contract to develop a ground test demonstration of a rotating engine detonation concept. Joining Pratt on the project will be sister companies under ...

There have been published papers by the Air Force Research Lab and NASA on rotating detonation engines having 10% or more efficiency gains. A rotating detonation engine (RDE) uses a form of pressure ...

A self-propagating series of explosions, contained between the blades of a high-speed rotor, promises a leap in power and efficiency during hypersonic flight – provided this radical new engine can be ...

WASHINGTON--With its strong dependence on gas-turbine engines for propulsion, the U.S. Navy is always looking for ways to improve the fuel consumption of these engines. At the Naval Research ...

A Florida team working with the US Air Force claims that it's built and tested an experimental model of a rotating detonation rocket engine, which uses spinning explosions inside a ring channel to ...
