定向战斗部毁伤效能评估

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.
