US Air Force technology promises to improve efficiency for high-speed aircraft, but big hurdles remain As part of ongoing research efforts to develop a practical pulse detonation engine (PDE), the US ...

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.

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, ...

Chinese scientists have once again innovated a new technology—and not just any technology, but an extraordinary new engine that could improve rotating detonation engines. It could have profound ...

Add Yahoo as a preferred source to see more of our stories on Google. Researchers in China have introduced a new hypersonic engine concept by integrating a ramjet with a rotary detonation engine. A ...

Astrobotic completed a successful series of hot-fire tests of its rotating detonation rocket engine prototype, marking a key milestone for the experimental propulsion technology.

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 ...
