Oblique detonation engine combustion chamber experimental device with variable wedge angle and starting point

The invention discloses an inclined detonation engine combustion chamber experimental device with a variable wedge angle and a variable starting point. The inclined detonation engine combustion chamber experimental device comprises a front connecting part, a rear connecting part and a combustion chamber arranged between the front connecting part and the rear connecting part. A wedge is machined in the combustion chamber, and the angle and the starting point position of the wedge can be adjusted according to the pressure intensity, the temperature, the equivalence ratio and the mixing uniformity degree of incoming flow combustible gas; fuel injection holes are distributed in the surface of the inclined wedge, and fuel can be injected in the rear area of the inclined detonation wave surface so as to change the wave system structure in the combustion chamber or the thrust of the inclined detonation engine. Observation windows are installed on the left wall face and the right wall face of the combustion chamber s
