摘要
提出了二次爆炸杀伤战斗部的概念并阐述了其相关作用原理,用实验验证了二次爆炸杀伤战斗部原理的可行性。针对选定的炸药装药,设计了二次爆炸杀伤战斗部的实验弹结构,利用高速摄影机拍摄实验弹的爆炸过程,确定二级装药在一级装药爆炸作用下是否发生XDT或DDT、测量起爆延迟时间和二级装药发生爆轰时其距初始位置的距离。结果表明,当有机玻璃隔板厚度值为50～80mm时,二级装药发生稳定的XDT或DDT,起爆延迟时间为2125～11000μs,二级装药产生的位移为252～645mm;采用钝感炸药装药,在特定的条件下会发生起爆时间更长的爆轰。XDT或DDT原理可应用于杀伤战斗部技术,提高杀伤破片的分布密度和速度。
Bi-blasting fragmentation warhead concept is proposed and related theory is described.An experiment was conducted to prove the rightness of bi-blasting fragmentation warhead principle.To verify the feasibility of the program,sample warheads with a chosen kind of explosive are designed and a high-speed video camera system was used to record the whole explosion process of the warheads.XDT or DDT phenomenon of Charge IIs occurring or not under loaded by ChargeⅠ,initiation delayed time and its displacement from initial position could be obtained by the experiment.The result shows that Charge IIs behave steady XDT or DDT with PMMA attenuator thickness between 50mm and 80mm,initiation delayed time are between 2 125μs and 11000μs correspondingly,and the displacement of Charge II from initial position are between 252mm and 645mm correspondingly.Charges with some insensitive explosives may occur XDT or DDT under special condition,and initiation time is even longer than the usual.The theory of XDT or DDT of explosive charges can be applied into fragmentation warhead technology to increase the distribution density and velocity of fragments.
