EAK基熔铸分子间炸药的能量和撞击感度

通过水下爆炸试验研究了RDX和HMX对EAK基熔铸分子间炸药水下能量的影响。结果表明，RDX和HMX对EAK基混合炸药起到明显的增能作用，但对含铝和非含铝体系有不同的作用效果。爆速和撞击感度测定表明，EAK—RDX混合炸药爆轰的理想化程度和稳定性及撞击感度随RDX含量的增加而增加。从能量和撞击感度两个方面综合考虑，RDX的较佳加入量应为20％～30％。

The Energy and Impact Sensitivity of EAK Based Melt Cast Intermolecular Explosive

The effect of RDX and HMX on the energy of EAK based melt cast intermolecular explosive was investigated by the underwater detonation energy testing which was carried out in a water pool with a diameter of 10 m and depth of 7 m, and the samples were about 300 g and set at 4 m under the water. The results indicated that all of RDX and HMX promoted the energy of EAK composition, but there was difference between aluminized and non-aluminized explosive composition systems. In the aluminized explosive compositions RDX was more effective on promoting underwater energy than HMX,but in the non-aluminized explosive compositions, HMX was more effective than RDX. The tests of detonation velocity and impact sensitivity for the EAK-RDX mixtures showed that ideality and propagation stability of detonation, and impact sensitivity all increased with increasing the content of RDX. The mixtures containing 20% and 30% RDX could come to a detonation velocity of 7 800 m/s and 8 000 m/s respectively, and their impact sensitivity both were less than 10%. The impact sensitivity increased sharply as the content of RDX was higher than 40%, while the detonation velocity just showed a smooth increasing. According to tradeoff between the energy and the impact sensitivity, the suitable content of RDX in the EAK composition was about 20% to 30%.
