Russian powerplant specialist United Engine has carried out initial testing of a pulse-detonation rocket motor which has potential application to orbital spaceplanes or hypersonic aircraft.

Tests of an advanced pulse detonation engine (PDE) design are coming closer than ever to proving the viability of the concept. Potential applications range from supersonic unmanned combat air vehicles ...

Engines that convert chemical energy from fuel into kinetic energy via explosive detonation, rather than slower deflagration combustion as seen in typical internal combustion engines. Categories ...

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, ...
