摘要
为探讨炸药低易损性的测试方法,系统研究以奥克托金(HMX)为基的含铝炸药的低易损性能(LOVA)。基于美军标《非核弹药危险评估试验标准》、北约《不敏感弹药评估和试验方法》和国内相关试验方法,通过开展慢烤、快烤、射流撞击、12.7 mm子弹撞击、12.7 mm破片撞击和殉爆等6项标准试验,从样品残余状态、弹体损坏状态、验证板破损状态、冲击波超压和爆炸场温度等方面综合评价药剂的易损性。结果表明:HMX基含铝炸药对外界多种刺激不敏感,可承受较高的过载,能满足大多数高性能战斗部装药要求,测试方法的可行性被验证。
To evaluate the low vulnerability of an HMX-based aluminized explosive,tests were carried out,including slow cook-off tests,fast cook-off tests,shaped charge jet impact tests,12.7 mm bullet impact tests,12.7 mm fragment impact tests and sympathetic detonation tests,according to MIL-STD-2105 D,NATO STANAG4439 and domestic correlative standards.Then the LOVA performances of explosive were judged by analyzing the residual of samples,the damage state of projectiles and verification boards,shock wave overpressure and temperature distribution.The results show that the explosive is insensitive to external stimuli,that it can withstand high overloading and satisfy the requirements of most warheads of high performance weapons,and that the test approach is practical.
