Problems solved by technology
There are few studies on converting the thrust of the detonation wave into the rotating mechanical energy of the shaft. The usual solution is to install a turbine at the outlet of the detonation tube to drive the turbine with the detonation combustion wave, as in the Chinese patent application published on January 7, 2009 No. CN101338702A discloses a pulse detonation rotor shaft engine, but this design still has some defects, such as the detonation cycle is easily affected by the turbine, which in turn affects the generation of detonation waves. In addition, this design also faces the power extraction of detonation waves. Unfavorable factors such as difficulties, difficulty in uniform atomization of fuel, difficulty in generating stable and continuous detonation waves, difficulty in detonation chamber exhaust gas, etc.

Description
technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a pulse detonation rotary engine. Background technique [0002] Pulse detonation engine is a new concept engine based on detonation combustion, which uses detonation wave to generate thrust to do work. The efficiency of the shock engine can reach 47% (the thermal efficiency of constant pressure combustion is 27%), so it has a good application prospect in the fields of unmanned aerial vehicles and missiles. [0003] A lot of research has been done on pulse detonation engines at home and abroad. Research centers such as NASA and AMES in the United States have also proposed single-tube solenoid valve control detonation engines. Domestic units such as Northwestern Polytechnical University and Nanjing University of Aeronautics and Astronautics have also carried out pulse detonation engines. basic research work. However, the current research on pulse detonation engines ma...
