Abstract:

为研究以HMX为基的固体高能炸药的燃烧转爆轰性能,采用同轴电探针和压力传感器测试技术对常用的A、B两种压装高密度高能炸药开展燃烧转爆轰实验,研究装药组分和约束条件对压装高密度炸药燃烧转爆轰性能的影响。实验结果表明:这两种压装高密度炸药难以发生燃烧转爆轰;在强约束条件下(45号钢,内径25.4mm、外径65mm、长度600mm),A压装炸药(HMX质量分数为95%,密度为1.86g/cm3)基本实现了燃烧转爆轰,爆轰诱导距离约为545mm;在相同的实验条件下,A压装炸药比B压装炸药(HMX质量分数为87%,密度为1.84g/cm3)更易于发生燃烧转爆轰,即A压装炸药的安定性相对较差。
