摘要
瞄准式战斗部的最佳起爆延时与传统周向均匀战斗部有很大区别,相关研究很少,因此需要对其进行系统研究。通过静爆试验得到瞄准式战斗部破片的分布数据,并据此计算出了战斗部静态条件下的威力半径。利用导引头失效前某一时刻所测参数和引信探测到目标初始时刻的参数,结合最佳起爆距离研究结论,通过计算剩余飞行时间,推导出了战斗部的最佳起爆延时。仿真计算结果验证了模型的正确性,同时得出,为避免引信探测到目标前目标就运动到最佳起爆距离处的情况出现,破片束静态锥角应大于等于8.2°。
The optimal initiation delay of gimbaled warhead is much more different from the initiation delay of conventional uniform warhead, and the related research is insufficient. The fragments dispersion data is obtained through static explosion experiment. On the basis of the data, the damage arrange of the gimbaled warhead has been calculated out. In conjunction with the conclusion of optimal initiation distance, the optimal initiation delay of gimbaled warhead is deduced by calculating residual flight time using the parameters detected by the seeker and fuse. The simulation results indicate the validity of the model. And for avoiding the target reaching to the optimal initiation point before being detected by the fuse,the cone angles should be greater than or equal to 8.2°.
