当弹丸的质量和质心变化后,其外弹道会相应的发生变化。为解决弹丸质量和质心大幅度变化后的弹道拟合问题,文章提出了一种以弹丸质心运动微分方程组为模型,采用估算弹道系数与误差拟合修正相结合的弹道拟合方法,解决了拟合系数法难以保证全弹道一致精度的难题。通过实测数据对该方法的检验,表明该方法具有一定工程应用价值。

When the projectile＇s mass and center of mass changes,its external trajectory will change accordingly.To solve the fitting problem after projectile mass and center of mass trajectory＇s significant change,this paper presents a trajectory fitting method using the ballistic coefficient and estimation error fit,based on the projectile mass motion differential equations,which solves the problem that the fitting coefficient method is difficult to ensure accuracy of the whole trajectory.The testing of measured data indicates that the method has some value in engineering.
