设计了一台内径50 mm、总长1500 mm的脉冲爆震发动机。汽油用作燃料，空气用作氧化剂。Shchelkin螺旋被用作爆燃转爆轰加速器。对脉冲爆震发动机进行了直连试验，研究了不同工作频率下爆震发动机的起爆和推进性能。实验结果表明，在1-35 Hz的工作频率范围内，爆震波在脉冲爆震发动机中被充分激发。随着工作频率的增加，脉冲爆震发动机的平均推力近似线性增加，而最佳当量比逐渐减小。随着工作频率的增加，体积比冲和混合比冲的增加趋势相似。随着工作频率从0增加到25 Hz，燃油比冲急剧增加，而燃油消耗率迅速下降。当工作频率超过25 Hz时，燃油比冲和燃油消耗率变化不大。另外，考虑两相效应，分别采用Winnberger模型和Yan模型计算了混合气比冲和燃料比冲。与实验结果相比，两种计算模型得到了相似的相对于工作频率的变化趋势。但Winnberger模型计算的混合比冲和燃料比冲值远高于实验值。考虑两相效应后，混合气比冲和燃料比冲的计算值与实验值接近。
A pulse detonation engine with the inner diameter of 50 mm and total length of 1500 mm was designed. Gasoline was used as the fuel and air as the oxidizer. The Shchelkin spiral was used as the deflagration to detonation transition accelerator. The direct-connected test of the pulse detonation engine was conducted to find out the detonation initiation and propulsion performance at several different operating frequencies. The experimental results indicated that detonation waves were fully initiated in the pulse detonation engine at the operating frequency range of 1–35 Hz. As the operating frequency increased, the pulse detonation engine average thrust increased nearly linearly, while the optimum equivalence ratio decreased gradually. The volume-specific impulse and mixture-specific impulse had the similar increasing trend at the increased operating frequency. As the operating frequency increased from 0 to 25 Hz, the fuel-specific impulse increased dramatically while the specific fuel consumption decreased quickly. The fuel-specific impulse and specific fuel consumption changed slightly when the operating frequency exceeded 25 Hz. In addition, two groups of computational value of mixture-specific impulse and fuel-specific impulse were obtained by Winternberger model and Yan model considering the two-phase effect. Compared with the experimental results, similar variation trends relative to the operating frequency were achieved by the two computational models. However, the computational values of mixture-specific impulse and fuel-specific impulse by Winternberger model were much higher than that of experimental values. When two-phase effect was considered, the computational values of mixture-specific impulse and fuel-specific impulse were close to that of experimental values.
