In typical jet engines, about 20 fuel injection nozzles are arranged around the annular combustion chamber of the engine. The turbulent combustion of the fuel there generates sound waves.

Particularly promising is the so-called rotating detonation engine in which detonation waves propagate continuously around an annular combustion chamber at high frequency and thus generate ...

The rotating detonation engine consists of a combustion chamber that has a annular, ring-type construction. In this ring, fuel and oxidizer is injected, and ignited in such a way to detonate the ...

Such an engine would use supersonic detonation waves in an annular chamber to achieve highly efficient combustion, with a rotor aiding in fuel-air mixing, compression, and thrust optimisation.
