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.

Pulse detonation technology being pursued by General Electric, Pratt & Whitney and Rolls-Royce offers engine-makers the potential for improving gas turbine specific fuel consumption by double digits ...

Continuing high fuel costs and growing environmental pressures could inject new urgency into development of pulse-detonation engine (PDE) technology for wider commercial applications, rather than just ...

Researchers at the National Energy Technology Laboratory (NETL) have designed and tested a key ...

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.

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 ...

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 ...
