摘　　要：文中首先建立了一定坐标系下的航空子母弹的运动微分方程组,并将它作为航空子母弹弹道系数值优化的数学模型,然后分别计算弹道系数为准确值和近似值时的航空子母弹的射程,把相应的射程分别作为准确值和近似值,并计算射程的误差大小,最后根据射程误差确定输入机载计算机的弹道系数的优化值。In the paper first kinematical differential coupled equation of the aviation cluster bomb is established on certain coordinate system,and it is used as optimum mathematical model of the ballistic coefficient value, then range of the bomb is respectively calculated when the ballistic coefficient is accurate and approximate ,corresponding range is taken for accurate value and approximate one ,and error size of range is calculated, finally according to error size of range the optimum value of the ballistic coefficient is decided.
