Abstract

LIMITED INITIATION ENERGY OR EXTERNAL STIMULATION MAY CAUSE INCOMPLETE DETONATION IN A WARHEAD. AT PRESENT, THERE IS NO QUANTITATIVE METHOD TO CHARACTERIZE THE ENERGY RELEASE OF A WARHEAD CHARGE FOR INCOMPLETE DETONATION SUCH AS EXPLOSION AND DEFLAGRATION. WE PROPOSE A METHOD BASED ON AVERAGE FRAGMENT QUALITY TO CHARACTERIZE THE ENERGY RELEASED BY A WARHEAD CHARGE. THE THEORETICAL STUDY SHOWS THAT THE AVERAGE FRAGMENT QUALITY AFTER WARHEAD INITIATION IS INVERSELY PROPORTIONAL TO THE INITIAL FRAGMENT VELOCITY. THE RELATIONSHIP BETWEEN THE AVERAGE FRAGMENT QUALITY AND EXPLOSIVE ENERGY RELEASE IS ESTABLISHED AND VERIFIED BY EXPERIMENT. THIS RELATION CAN BE USED TO DETERMINE THE CHARGE ENERGY RELEASED AFTER WARHEAD INITIATION. IT PROVIDES A THEORETICAL BASIS FOR OPTIMIZING EFFICIENCY OF CHARGE ENERGY USE IN HIGH-ENERGY CONVENTIONAL DAMAGE TECHNOLOGY AND WARHEAD DESIGN, AND PROVIDES A QUANTITATIVE METHOD FOR EVALUATING INSENSITIVE AMMUNITION.
基于平均碎片质量评估弹头装药释放能量的方法
有限的起爆能或外部刺激可能导致弹头不完全起爆。目前还没有定量的方法来表征爆炸、爆燃等不完全起爆战斗部装药的能量释放。提出了一种基于平均破片质量的方法来表征战斗部装药释放的能量。理论研究表明,战斗部起爆后破片平均质量与破片初速成反比。建立了平均破片质量与爆炸能量释放的关系,并通过实验进行了验证。该关系式可用于确定战斗部起爆后释放的装药能量。为高能常规毁伤技术和弹头设计中装药能量利用效率的优化提供了理论依据,并为钝感弹药的定量评价提供了方法。
