摘要
从精确弹道计算所用的数学模型出发 ,指出了弹道导弹在自由段飞行中的两个具有明确物理意义的运动守恒量 ,并给出了用发射坐标系下的运动参数求这些守恒量的简洁计算公式。这两个守恒量可作为一种简单。
By analyzing the high precision motion equations of ballistic missile, this paper presents two conservation quantities that have a definite physical meaning in the free phase trajectory. Succinct formulas are provided to calculate such conservation quantities by motion parameters under launch coordinates. Owing to its simplicity and easy computation, the conservation quantities can be used as an assistant means to check the reliability of trajectory computation result and launch elements of the missile.
