摘要

主要研究位于临近空间的高马赫平台内埋弹射导弹的发射分离安全性,采用数值计算方法分析在25 km高度不同攻角状态下导弹的分离姿态和安全性。仿真采用基于非结构网格的网格重构(remeshing)和弹簧光顺(spring smoothing)相结合的动网格技术,通过计算不同攻角下导弹的运动姿态和分离特性,从而确定攻角对导弹分离安全性的影响,为临近空间高马赫机载制导武器的分离安全研究提供参考。

Abstract

The launch separation safety of the missile embedded in the high Mach platform in the near space is studied. The separation attitude and safety of the missile at different attack angles at 25 km height are analyzed by numerical method. In the simulation, the dynamic grid technology based on unstructured grid reconstruction and spring smoothing is used to calculate the motion attitude and separation characteristics of the missile at different angles of attack, so as to determine the impact of the angle of attack on the separation safety of the missile, which provides a reference for the separation safety research of high Mach airborne guidance weapons in the near space.

Key words： embedded ejection; dynamic mesh; angle of attack; shock wave; separation safety
