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 ...

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 ...

Tsinghua researchers combine ramjet-based rotor compressor with a detonation engine which they say advances propulsion technology Chinese scientists proposing a new concept for a hypersonic engine ...

Scientists at the forefront of hypersonic weapons research in China say they have a more powerful revolutionary air-breathing engine. The “revolutionary” air-breathing engine could lift an aircraft ...

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 ...
