摘要
导弹冷发射出筒过程中,需要安装底罩来保护一级发动机,发射后要将底罩抛离并确保其不会砸到地面设备,设计了采用纵向分离加侧推的组合分离方案,采用推冲器作为纵向分离能源以及侧推发动机作为侧向移动能源。导弹底罩分离过程中受多种不确定性因素影响,考虑侧推发动机、推冲器、空气负压力以及阵风等多种因素对分离过程的影响,对导弹底罩分离过程建立了分离运动学和分离动力学模型。通过仿真得到相关参数对分离过程的影响,确定了分离设计参数值,最后利用蒙特卡罗方案得到底罩的横移和落区范围。
In the process of missile cold launch,trail cover installation is needed to protect the first-stage engine.After launch,the trail cover has to be separated from missile,so it is very important to avoid it from collision with any equipment on the ground.A scheme combining longitudinal separation with lateral fling is described,in which the pusher is used as longitudinal separation energy and solid rocket as lateral moving energy.In the process of separation,the missile trail cover is affected by multiple uncertain factors.The kinetics and kinematics models of trail cover separation are established considering solid rocket,pusher,air negative pressure,wind effects,etc.The effect of related parameters on the separation process is obtained,and the design parameters of the separation is determined.Finally,the lateral movement and landing range is obtained with the Monte-Carlo method.
