本文从工程实践出发,总结了箭弹上常用的若干种导旋方式的滚转角速度计算方法.用这些方法得出的结果,与风洞实验值或靶场飞行试验值基本一致.因此,这些计算方法可供箭弹滚转角速度计算或设计时参考. Based on the engineering practice, this paper summarizes some methods of calculating the angular velocity of the gyroscopes, which are commonly used in the missile projectiles.The results obtained by these methods are basically consistent with the experimental values ​​of the wind tunnel or the flight test of the shooting range.Therefore, The method is available for arrow rock roll angular velocity calculation or design time reference.
