Initial disturbance control for multiple launching rocket system

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.
