摘要
分析了弹丸在飞行过程中质量衰减（如底排增程弹和底排－火箭复合增程弹）对其主要结构特征数的变化影响，建立了一种与四自由度修正质点弹道或六自由度刚体弹道的弹道计算模型相配套的计算模型，经算例验证该模型计算准确可靠．
In this paper, it is analyzed that the effect of the changing physical characteristic parameters of a projectile, such as base bleed projectile and base bleed rocket assisted projectile in the flight. A calculation model of four dimensional and six dimensional ballistic equations is constructed, the result indicates that model is precise and reliable.
