To investigate the effect of HMX on the low vulnerability characteristic of solid propellant, including responses upon projectile impact, fragment impact, and jet impact, these experiments have been conducted on two kinds of typical solid propellants. The difference between these two propellants is one contains 20 % of HMX(Sample A), and the other one is blank(Sample B). The results showed that the response type of A and B are burning in projectile impact tests and fragments impact tests. In contrast with projectile impact tests, the combustion rates in fragments impact tests were increased faster. When there is a small amount of HMX in formula, the burning rates in axial and radial tests were increased by 4.44 and 1.14 times, respectively. The impact responsive degree of propellant in axial tests is 1.61 times higher than that in radial tests. In jet impact tests, A detonated while B burned rapidly, which means HMX has obvious effect on the responsive characteristic of composite solid propellant in jet impact tests. © 2019, Editorial Dept. of JSRT.
