MULTI-HOLE FINE TUBE PLATE FOR SUPPLYING FUEL OXIDIZING AGENT FOR PULSE DETONATION ENGINE

摘要

PROBLEM TO BE SOLVED: To solve the following problems: An operating frequency of a fuel oxidizing agent supply valve in a pulse detonation engine limits performance of the engine. When the detonation wave is ignited without using a bulb, because the detonation wave propagates in the flow direction of the fuel and the oxidizing agent, efficiency is lowered and fuel and oxidizing agent are discharged in the exhaust period of the burnt fuel. Because mixing of the fuel and oxidizing agent having ultrasonic relative velocity is easy to become insufficient, detonation waves are not generated. SOLUTION: The oxidization agent supply plate separately injects fuel and oxidizing agent from a number of fuel holes having a complicated shape for promoting the mixing of the fuel and oxidizing agent, and serves as a plate for receiving rearward pressure of the detonation wave.
