摘　　要：准确的毁伤效能评估能够更加全面地分析评估战斗部的威力,对战斗部的评估和优化具有重要指导意义。定向战斗部能够提高弹载装药的能量利用率,但是其毁伤效能评估并不完善。针对定向战斗部毁伤评估存在的关键难题建立柱坐标系下引信-战斗部配合模型,考虑弹体的滚转角因素,基于激光周向探测引信提出最佳起爆延时和最佳起爆方位计算方法,通过实验验证的数值模型提取威力场打击迹线数据,最终形成适用于定向战斗部的毁伤效能评估程序。利用该程序计算不同定向战斗部结构对某直升机目标的毁伤概率,结果表明:圆柱和棱柱两种战斗部对目标的毁伤概率都随着弹目距离的增大而减小,但是棱柱型战斗部减小幅度远小于圆柱战斗部;棱柱型战斗部在30 m弹目距离时对该直升机目标的毁伤概率仍然能达到0.538.The power of warhead can be more comprehensively analyzed and evaluated through accurate damage effectiveness evaluation.The directional warhead can be used to improve the energy utilization rate of ammunition-carrying charges,but the damage effectiveness evaluation of directional warhead is not perfect.In view of the key problems in the damage evaluation of directional warhead,a cylindrical coordinate fuze-warfare coordination model was established,in which the roll angle of projectile is considered.Based on the laser circumferential detection fuze,a calculation method was presented for the optimal initiation delay and the optimal initiation azimuth.The field strike trajectory data was extracted from the verified numerical model,and finally a damage effectiveness evaluation program suitable for directional warheads was established.The program is used to calculate the damage probability of directional warheads to helicopter target.The results show that the damage probabilities of cylindrical and prismatic warheads to the target decreases with the increase in the projectile-target distance,but the damage probability of prismatic warhead decreases much smaller than that of cylindrical warhead.The prismatic warhead still has a 0.538 damage probability to the helicopter target at a distance of 30 m.
