摘要
为解决火箭弹起始扰动对多管火箭射击精度具有重大影响的问题,该文采用通过控制定向管角运动来减小火箭弹起始扰动的方案提高多管火箭射击精度。应用受控多体系统传递矩阵法和发射动力学理论,建立了受控多管火箭发射控制动力学模型,数值仿真获得多管火箭定向管角运动对起始扰动的影响规律及多管火箭定向管角运动的控制规律。该文控制火箭弹起始扰动的方法为提高射击精度提供了手段。
In order to solve the problem that the initial disturbance of the rocket projectile has a serious effect on firing accuracy of the multiple launching rockets system （MLRS） , this paper uses launcher angular motion control to reduce the initial disturbance of rocket projectile for improving the MLRS firing accuracy. The transfer matrix method of controlled multibody system and the theory of launch dynamics are used to establish a model of launch dynamics with control for multiple launch rockets. The effect law of launcher angular motion on initial disturbance and the control law of the launcher angular motion are obtained by numerical simulation. The method of controlling the initial disturbance of rocket provides a new means to improve firing accuracy of MLRS.
