摘要：

Due to the huge differences in pressure and duration of dynamic loading process and quasi-static loading process in high-pressure water jet impacting HTPB propellant, possible ignition modes were prejudged on the basis of the calculation of water hammer pressure and stagnation pressure, and the safety of dynamic loading process and quasi-static loading process were analyzed through model analogy and experimental study respectively. The results show that there is no detonation risk in the dynamic loading process of high pressure water jet with the outlet pressure less than 300 MPa, but in the quasi-static loading process of high pressure water jet the outlet pressure of which is above 100 MPa. It is possible that internal temperature has a sudden rise, which may cause thermal ignition or even thermal explosion. ©, 2015, Explosion and Shock Waves. All right reserved.
