| 摘 要： | 为了探索气－液两相脉冲爆震发动机模型内特征参数对产生爆震波的影响规律，系统地测试了以汽油为燃料、以空气为氧化剂的气－液两相脉冲爆震发动机模型在不同点火频率及不同余气系数下爆震波的峰值压力以及平均爆震波速，并对其变化进行了分析。通过分析实验结果发现，当余气系数σ增大时，爆震波发动机性能下降，在爆震室长度一定时，点火频率等于脉冲爆震频率。

| Abstract: | In order to investigate the influence of characteristics parameters on detonation wave in a two-phase pulse detonation engine model.The peak detonation pressures and average velocities of two-phase pulsed detonation wave produced by PDE model using gasoline as fuel and air as oxidizer under various ignition frequencies and various mixture ratios are measured systematically, and the relations influencing them are analyzed. The experimental results have shown that for a given length of PDE model the performance of PDE model decreases with increase of α and the ignition frequency is equal to the pulse detonation frequency. |
