导弹套接分离方案级间分离过程仿真分析

Simulation of Stage Separation Movement of a Sleeve-connected Missile

针对采用套接式分离方案的固体导弹,在套接式分离方案特点分析基础上,建立了导弹分离动力学模型。就不同发射条件和设计参数进行了级间分离过程仿真分析,获得发射角、发射点海拔高度、发动机后效推力、套简长度、防转螺钉距套筒出口长度对分离时间和主级导弹制导信号被遮挡时间的影响规律。文中对导弹套接式分离方案发射条件选择和级间分离装置设计具有一定参考价值。

This paper aiming at a sleeve-connected missile,built the separation dynamics model by analyzing the features of sleeve-connected separation project.Then simulated the separation process under some launching conditions and some missile parameters,deduced the disciplines of separation process time spending and the process main sector controlled signal sheltered by booster time spending by five influential factors:launching angle,launching height above sea level,residual motor thrust,sleeve length and distance between the anti-rolling bolt and the sleeve end.Some reference value of selecting the launching conditions and the missile parameters could be obtained in this paper.
