Researchers in China have introduced a new hypersonic engine concept by integrating a ramjet with a rotary detonation engine. A team at Tsinghua University in Beijing created a new design known as the ...

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 ...

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 ...
