Abstract

The invention relates to a rotating detonation engine experimental device, which belongs to the field of engine research. Including end cover, outer wall, inner cavity and fuel input control ring; screw holes and oxygen input port are distributed on the end cover; screw holes, fuel input port, igniter placement port and sensor placement port are distributed on the outer wall; There are screw holes, the oxygen is at the entrance of the annular combustion chamber, and the fuel is at the entrance of the annular combustion chamber; through holes are distributed on the fuel input control ring; in the rotary detonation engine experimental device of the present invention, the diameter of the oxygen at the entrance of the annular combustion chamber is 1mm , the number reaches one hundred; it can make the fuel and oxygen mix more evenly, and increase the possibility of continuous rotating detonation in the annular pipeline.

Description

technical field [0001] The invention relates to a rotating detonation engine experimental device, which belongs to the field of engine research. Background technique [0002] The rotary detonation engine is a new type of detonation engine. Since the detonation wave exists in the annular combustion chamber for a long time and is always in motion, there is no need for high-speed incoming flow and non-stop ignition, and there is no noise induced by the detonation outlet. The detonation wave in the annular combustion chamber continuously rotates and propagates along the circumferential direction, and the high-pressure detonation products expand rapidly and are discharged at high speed in the axial direction, thereby generating propulsion. Therefore, in terms of propulsion, the rotary detonation engine has some advantages of the pulse detonation engine and the stationary detonation engine at the same time, namely: zero start, low noise, low pollution of detonation products, high...
