Abstract

The invention discloses a rotary detonation combustion chamber suitable for gas-liquid two-phase dual fuel. The rotary detonation combustion chamber is mainly composed of a liquid fuel supply cavity, a gaseous fuel supply cavity, a rotary detonation combustion annular cavity and gas film cooling holes. In order to solve the problems of poor detonation characteristics and poor stable propagation characteristics of liquid fuel rotating detonation waves, in the detonation stage, gas fuel with good detonation performance is jetted in rotating detonation combustion, stable transmission based on the gas fuel rotating detonation waves is achieved firstly, and then stable propagation based on the liquid fuel rotating detonation waves is achieved. When the structural complexity of the combustion chamber is not obviously increased, the gas fuel injection structure is additionally arranged, the success rate of detonation of the liquid fuel rotating detonation waves is increased, the stable transmission characteristic of the rotating detonation waves is improved, and the invention is very important for engineering application of the rotating detonation combustion chamber.
