Abstract:

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 〖JP2〗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.
