为研究激光驱动飞片起爆装置中加速膛刀口直径对输出飞片速度的影响,利用Lawrence Gumey模型进行了理论分析,并设计了不同直径的刀口进行切割聚酰亚胺膜和冲击起爆HNS-Ⅳ试验。理论分析和试验结果均表明:随着加速膛刀口直径减小,输出飞片的速度增大,产生的冲击强度增大;试验未能成功起爆HNS-Ⅳ,但随着加速膛刀口直径的减小,药剂部分发生了反应。
In order to study the influence of accelerating bore diameter on output flying-film speed in laser-driven flyer detonating device, the theoretical analysis was conducted by using Lawrence Gumey model, and the cutting of polyimide film and impact initiator HNS-Ⅳ test. The theoretical analysis and experimental results show that the velocity of the output flyer increases and the impact strength increases with the decrease of the diameter of the accelerating bore. The HNS-Ⅳ can not be successfully detonated by the test, however, Small, pharmaceutical part of the reaction.
