摘要: 为提高吸气式脉冲爆轰发动机的推力,进行了中心锥鳞片阀与中心锥钝体阀吸气式脉冲爆轰发动机(PDE)的对比试验研究,并对多循环吸气式脉冲爆轰发动机工作过程的受力状况进行分析。研究结果表明:采用压电式力传感器能准确测量多循环吸气式脉冲爆轰发动机的平均推力;在10 Hz相同工况下,中心锥鳞片阀吸气式PDE的平均推力是中心锥钝体阀吸气式PDE平均推力的2.05倍。研究结果对多循环吸气式PDE推力的直接测量以及提高吸气式PDE的推进性能具有重要意义。

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.
