母舱机动分导的思想就是通过母舱的机动来实现子弹头的分导。母舱内有控制舱(它们往往也是整个导弹的控制舱)和末助推推进舱。母舱内装有3～10枚子弹头,每个子弹头都不再有控制系统和助推器。母舱与运载火箭分离后就沿着自由弹道飞行。在分导机动前,母舱姿态控制系统使末助推发动机的推力矢量指向事先确定的程序方向。分导机动期间,制导系统控制末助推发动机的关机时间以得到释放子弹头所需要的速度增量,并通过关机与导引使机动期间于扰引起的方法误差最小。
The idea of a mainshift maneuver is to realize the subduction of the projectile by maneuvering the mother’s cabin. The control cabin in the mother’s cabin (they are often also the control cabin of the entire missile) and the final boost propulsion cabin. There are 3 to 10 projectiles in the mother’s cabin, and no control system and booster are available for each projectile. After the separation of the mother’s cabin from the launch vehicle, a free-range flight follows. Before the splitter maneuver, the attitude control system of the mother cabin directs the thrust vector of the final boost engine to a predetermined program direction. During the maneuvering period, the guidance system controls the power-off time of the booster engine to obtain the required speed increment to release the projectile and minimizes the method disturbances during maneuvering caused by shutdown and guidance.
