Astrobotic completed a successful series of hot-fire tests of its rotating detonation rocket engine prototype, marking a key ...

More than 60 years ago, scientists in the United States imagined a powerful engine that could push aircraft to hypersonic speeds—up to 16 times the speed of sound. This dream involved something called ...

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, ...

Add Yahoo as a preferred source to see more of our stories on Google. Researchers in China have introduced a new hypersonic engine concept by integrating a ramjet with a rotary detonation engine. A ...

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 ...

Oblique detonation waves (ODWs) represent an advanced class of shock-induced combustion phenomena in which the detonation front propagates at an angle to the oncoming supersonic flow. These waves are ...

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 ...

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 ...
