Abstract: In order to improve the thrust of air-breathing pulse detonation engine, the air-breathing pulse detonation engines with central cone-scales valve (CCSV) and central cone-blunt valve (CCBV) are investigated, and the force condition of multi-cycle air-breathing pulse detonation engine during working is analyzed. The results show that the average thrust of multi-cycle air-breathing pulse detonation engine can be accurately measured by using the piezoelectric force sensor. Furthermore, the average thrust of air-breathing pulse detonation engine with CCSV is 2.05 times as high as that of the engine with CCBV at 10 Hz. For this point of view, the results are significant to the direct measurement of the thrust of multi-cycle air-breathing pulse detonation engine and the improvement of the propulsion performance of air-breathing pulse detonation engine.
