摘　　要：为了优化和选择吸气式脉冲爆轰发动机的混合室结构,设计了不同长度的混合室以及不同结构的内部元件,包括细管蒸发器和掺混器。试验研究了混合室长度和内部元件对吸气式脉冲爆轰发动机的影响。结果表明,对于一定结构的吸气式脉冲爆轰发动机,存在一个最佳的混合室长度;混合室长径比为2.5时,爆轰效果最佳。In order to optimize and select the structure of the mixing chamber of the air-breathing pulse detonation engine, the mixing chambers with different length and internal components are designed, including small-tube evaporators and mixing devices. The effect of the length of mixing chambers and internal components on the air-breathing pulse detonation engine is researched experimentally. The results show that, there exists an optimum length of the mixing chamber for a certain air-breathing pulse detonation engine, and the best detonation results can be obtained when the length-diameter ratio of a mixing chamber is 2.5.
