摘要:
为了研究HMX含量、粒径和形貌对复合推进剂临界起爆压力的影响,对设计出的7组配方开展了临界起爆条件试验,计算了相应的冲击波临界起爆压力。结果表明,HMX质量分数分别为5%、10%、15%时,推进剂的临界起爆压力分别是15.40、 7.99、 7.55 GPa;HMX质量分数相同,中位粒径分别为5.432、 6.482、 9.121、 136.800 μm时,推进剂的临界起爆压力分别是7.99、 7.99、 9.42 ~15.40、 9.04 ~15.40 GPa;当HMX的颗粒分布跨度较大时,临界起爆压力为7.99 GPa。随着HMX的含量在一定范围内增高,复合推进剂的临界起爆压力减小;随着HMX的中位粒径增大,复合推进剂的临界起爆压力增大;颗粒的类球形结构能大幅提高临界起爆压力。
Abstract:
Seven types of HMX samples were tested at their critical initiation conditions and corresponding critical initiation pressures of shockwave were calculated to analyze the influence of the content, particle size and appearance of HMX on the critical initiation pressure of composite propellant. The results show that the critical initiation pressures are 15.40, 7.99 GPa and 7.55 GPa at the HMX content of 5%, 10% and 15%, respectively; the critical initiation pressures at a fixed amount of HMX are 7.99, 7.99, 9.42-15.40 GPa and 9.04-15.40 GPa at various medium particle sizes of 5.432, 6.482, 9.121 μm and 136.800 μm, respectively. The critical initiation pressure is 7.99 GPa when HMX shows a large particle distribution. It shows that the critical initiation pressure decreases with the increase of HMX content in a certain range; the critical initiation pressure increases with the increase of the medium particle size of HMX; and spherical-like structure of the particle has a great influence on the critical initiation pressure.
