点火药药量对爆炸能量输出影响的试验研究

Experimental Research on the Effect of Ignition Composition Quantity on the Explosion Energy Generation

现代作战对弹药低附带损伤和灵活性的要求越来越高,使得爆炸当量可调常规战斗部成为当前研究的热点之一。采用探针法、破片回收法等对不同质量点火药作用下压装8701炸药战斗部的输出能量进行了研究。研究结果表明,8701炸药在战斗部中较易实现燃烧转爆轰。随着引爆的点火药药量增加,战斗部装药的燃烧转爆轰越快,输出的能量也增大,壳体破碎程度也更充分,尤其是点火药在0.2～2.0g之间;当点火药药量达到5.0g时,战斗部装药可实现直接爆轰。研究结果还表明,通过控制点火药药量可以实现战斗部威力可调的目的。

The increasing demand of modern warfare on the low collateral damage and the flexibility of ammunition makes the explosion equivalent be the research focus. Probe method and fragment recovery method were used to investigate the output energy of press fitting 8701 explosive warhead with ignition loading at various quantities. Results show the easy transition of 8701 explosive from burning to detonation in warhead. As the charge quantity increases, especially within the range of 0.2-2.0g, the transition was accelerated accompanying with larger warhead generation energy and higher shell frag- mentation quality. When the charge quantity increases to 5.0g, the warhead charge reaches to the extent of direct detona- tion. Results of the study also show that ignition composition quantity control can be used in the quality adjustment of the warhead power.
