| 摘 要： | 为研究HTPB／AP复合推进剂装药直径对冲击波点火的影响作用，用隔板实验测试了不同装药直径对冲击波点火临界燃烧厚度及峰值压力的影响。确定了最佳药柱直径，并对其点火可靠性及药柱受冲击波点火后密度变化进行测试。结果表明，药柱直径与临界燃烧隔板厚度及冲击波强度有着密切的关系。密度为1．563g／cm^3时，HTPB／AP复合推进剂的最佳冲击波点火推进剂装药直径为40mm，且冲击波点火可靠性良好，药柱受冲击波作用后，密度发生一定变化。

| Abstract: | The influence of charge diameter of the HTPB/AP composite propellant on the igniting performance was studied. The effect of charge diameter on the thickness of clapboard and intensity of shock wave was tested by means of clapboard experiments and the optimal diameter was determined. The results show that there is a close relationship between the optimal diameter of HTPB/AP composite propellant and the thickness of clapboard and intensity of shock wave. The optimal diameter of ignition of composite propellant corresponding to p= 1. 563g/cm^3 is 40 mm. This experimental result has definite guiding significance for the design of composite propellant charge in benefieiate perforator and the enhancement of the effectiveness and reliability of igniting of composite propellant charge. |
