摘要
设计了一种非对称约束“D”字形定向战斗部,研究了该战斗部的毁伤效应影响因素,采用数值仿真方法计算了破片的空间分布和速度,同时开展静爆试验,证实了“爆试字形”定向战斗部毁伤效应。结果表明,“D”字形定方位圆弧直径与非定方位圆弧直径比值是影响定向区破片空间分布主要因素,定向方位破片质量与非定向方位破片质量比是影响定向区破片速度主要因素。相比传统回转体结构防空反导战斗部,该战斗部目标方向破片密度能够提升100%,极大提升毁伤威力。
A novel D-shape aimed warhead with asymmetric constraints was designed.The influence factors of D-shape aimed warhead on damage effectwere studied.The space distribution and the velocity of fragments were calculated by numerical simulation.Additionally,the static explosive experiment was carried out to verify the damage effect of D-shape aimed warhead.The results show that the diameter ratio between the directional and the non-directional positions of D-shape is the main factor affecting the space distribution of fragments in directional region,and the mass ratio between the directional and the non-directional fragments is the main factor affecting the velocity of fragments in directional region.Compared with the traditional revolving warhead for air defense and anti-missile,the fragment density in the target direction of the D-shaped directional warhead can be increased by 100%,which enhances the damage power in target position significantly.
