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 ...

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.

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, ...

Essentially, it's a rotating detonation engine in which the detonation wave is stabilized within a high-speed rotor. A precisely shaped flow channel within the rotor compresses the air-fuel mixture to ...

Rotating detonation rocket engines work differently than traditional rockets to maximize thrust while using less fuel—an advantage that could help spacecraft explore farther in the solar system ...

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 ...

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 ...
