Abstract

The invention relates to a rotation detonation engine experimental device, and belongs to the field of engine research. The rotation detonation engine experimental device comprises an end cover, an outer all, an inner cavity and a fuel input control ring. Screw holes and oxygen input openings are distributed in the end cover. Screw holes, fuel input openings, an igniter containing opening and sensor containing openings are distributed in the outer wall. Screw holes, in-annular-combustion-chamber oxygen inlets and in-annular-combustion-chamber fuel inlets are distributed in the inner cavity. Through holes are distributed in the fuel input control ring. According to the rotation detonation engine experimental device, the diameters of the in-annular-combustion-chamber oxygen inlets are each 1 mm, and the number of the in-annular-combustion-chamber oxygen inlets reaches 100; fuel and oxygen can be more uniformly mixed, and the possibility that continuous rotation detonation phenomena happen in an annular pipeline is improved.

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...
