某型预制破片弹超视距射击时毁伤效能研究

Research on Damage Efficiency of a Certain Type of Prefabricated Fragment Projectile in over Horizon Shooting

采用随机生成的弹道数据计算预制破片弹在超视距射击时毁伤效能的射击精度。建立了弹丸的预制破片爆炸场及其对装甲目标命中破片数和对人员目标杀伤面积的计算模型,基于Matlab编写了计算程序,计算不同飞散半径条件下,破片存速和球面密度以及包含50%落弹数区域的毁伤效能,对横偏和落高对命中装甲目标破片数和人员杀伤面积的影响进行了分析。

In order to study the damage efficiency of a certain type of trajectory correction prefabricated fragment projectile in beyond-line-of-sight shooting,the firing accuracy was calculated by using randomly generated trajectory data.The calculation model of the explosion field of the prefabricated fragment of the projectile was established,and the theoretical calculation model of the number of fragments hit the armored target and the killing area to the personnel target was established.The calculation program was compiled based on MATLAB.The damage efficiency of the fragment storage speed,spherical density and the area containing 50%of the number of dropped projectiles under different scattering radius conditions were calculated.The impact of lateral deviation and falling height on armored target was also discussed the influence of fragment number and kill area was analyzed.
