2种非TNT基熔铸炸药水下爆炸特性

为选择水下炸药中的主炸药,分析RDX与HMX在水下爆炸的能量输出特性差异,分别以RDX和HMX为主炸药,制备了2种非TNT基熔铸炸药R-RDX与R-HMX,并在直径为85 m的水池中进行水下爆炸试验,测试水下爆炸压力及脉动周期,计算冲击波能及气泡能.试验结果表明:在4~6 m范围内,R-RDX炸药的冲击波能为1.18 MJ/kg,气泡能为4.00 MJ/kg;R-HMX炸药的冲击波能为1.19 MJ/kg,气泡能为4.01 MJ/kg;对于非TNT基熔铸炸药,HMX作为主炸药同RDX相比,在水下爆炸时并无能量优势.

Underwater Explosion Characteristics of Two Non TNT Melt-cast Explosives

In order to choose a main explosive of underwater explosives, analyze the underwater explosion energy output characteristics of RDX and HMX. Separately use RDX and HMX as main explosives, produce R-RDX and R-HMX which are both non TNT melt-cast explosives. Underwater experiment was taken in a diameter of 85 m pool, the underwater explosion pressure and the pulse cycle was measured and shock wave and bubble energy was calculated. Result show that, within 4-6m, the shock wave and bubble energy of RDX based explosive was 1.18 MJ/kg and 4.00 MJ/kg, and HMX based explosive was 1.19 MJ/kg and 4.01 MJ/kg. Compared with RDX, HMX has no energy advantage in underwater explosion in non TNT melt-cast explosive.
