Detonation is a supersonic combustion wave, characterized by a shock wave driven by the energy release from closely coupled chemical reactions. It is a typical form of pressure gain combustion, ...

Rotating detonation engines (RDEs), as opposed to oblique wave detonation engines or pulse detonation engines, use ring-shaped chambers and precisely-timed fuel injection to generate constant thrust.

Two revolutionary aerospace technologies collide as GE Aerospace and Lockheed Martin team up to demonstrate a new ...

Last year, the Defense Advanced Research Projects Agency (DARPA) quietly unveiled a new high-speed missile program called Gambit. The program is meant to leverage a novel method of propulsion that ...

Scientists at the forefront of hypersonic weapons research in China say they have a more powerful revolutionary air-breathing engine. The “revolutionary” air-breathing engine could lift an aircraft ...

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 ...
