双元复合炸药装药水下爆炸能量输出特性

选择GH-1和GUHL-1两种炸药及内外层和上下叠加两种典型的双元装药结构,测量了水下爆炸冲击波超压-时间历程,研究不同双元装药水下爆炸的能量输出结构,并与单一配方装药进行了对比.实验结果表明: 同样化学组成下,采用双元炸药装药结构,能够改变水下爆炸测点处的爆炸载荷,减少冲击波在传播过程中的能量损失,提高能量利用率; 其中采用外层高爆速炸药,内层非理想炸药的同轴内外层双元装药结构,比单一配方装药的比气泡能提高22.4%,而且两部分装药之间产生了能量耦合效应.

Characteristic of Energy Output of Underwater Explosion for Dual Explosive Charge

By choosing two types of explosives GH-1 and GUHL-1, and two typical dual charge structures, the test samples were prepared. The characteristics of energy output of underwater explosion for dual explosive charge were studied and compared with that of the single explosive charge. The results show that under the same composition, the dual explosive charge can change the explosion load near the testing point, and decrease the energy loss of shock wave in the detonation propagation. By using dual explosive charge structure with a non-ideal explosive as an inner core surrounded by a high detonation velocity explosive, the bubble energy is increased by 22.4% compared with that of the single explosive charge, and also energy coupling exists in the two parts of the charge.
