摘　　要：航炮是武装直升机的主配武器之一,可以用于对地面目标打击以及直升机空战。探讨武装直升机航炮对地面有生力量毁伤的数学模型,着力分析目前破片杀伤计算模型不完善之处并进行修正。建立了新的破片飞散角计算模型;基于精确的数学模型计算目标受弹面积,利用MATLAB进行定积分计算,消除了对计算模型进行近似处理所产生的问题;在确定椭圆毁伤律参数时,建立了新的计算模型。提出的破片飞散角计算模型、目标受弹面积计算方法、椭圆毁伤律参数计算模型,也适用其他各类火炮对地面有生力量的毁伤计算。The aero cannon is one primary kind of weapon for the armed helicopter,which can be used to attack ground targets and helicopters.This paper discussed the mathematical model of armed helicopter aero cannon killing deployed infantry with the existing problems about present splashing fragment killing calculating method mainly analyzed and rectified.A new method for calculating the angle of splashing fragments was established based on the precise mathematical model calculate target killing area,using MATALB software to process definite integral,eliminating problems caused by approximate processing calculating model,and establishing a new calculating model for ellipse damage law parameter calculation.The angle-of-splashing-fragment calculating model,target killing area calculating method and ellipse damage law parameter calculating model proposed in this paper can also be used for other cannons in the case of calculating killing deployed infantry.
