Astrobotic Technology says it has fired a rotating detonation rocket engine at 4,000 pounds of thrust, a milestone that puts the Pittsburgh-based lunar logistics company at the leading edge of an ...

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.

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 ...

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 ...

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 ...
