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 ...

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 ...
