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 ...

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 ...

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 ...

Pittsburgh-based Astrobotic has completed a successful series of hot-fire tests of its rotating detonation rocket engine prototype Chakram, marking a key milestone toward bringing the experimental ...

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 ...

A new generation of space rockets is inching closer to launch. Private space company Astrobotic recently revealed it carried out a successful test of two of its rotating detonation rocket engines ...
