Tests of an advanced pulse detonation engine (PDE) design are coming closer than ever to proving the viability of the concept. Potential applications range from supersonic unmanned combat air vehicles ...

US Air Force technology promises to improve efficiency for high-speed aircraft, but big hurdles remain As part of ongoing research efforts to develop a practical pulse detonation engine (PDE), the US ...

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 ...
