为解决低速滚转末制导炮弹在高原环境下的适应性问题,对低速滚转末制导炮弹在不同海拔条件下飞行特性进行研究,分析了高海拔条件的环境特性,末制导炮弹在不同海拔条件下的转速和过载变化特性,弹体增益和弹体阻尼的变化情况,提出了低速滚转末制导炮弹在高原环境下使用的改进方法,并以某低速滚转末制导炮弹为例进行了弹道仿真,验证了分析结果和改进方法的正确性,为低速滚转末制导炮弹的高原适应性设计和改进提供了参考依据。

To solve plateau adaptability problems of low-speed roll terminal guidance projectile, flight characteristics of low-speed roll terminal guidance projectile at different altitude were researched. Changes of environment characteristics, rotational speed, overload, missile gain and damping characteristics of the terminal-guidance projectile at high altitude were analyzed. The plateau adaptability modification approaches for the low-speed roll terminal-guidance projectile were provided based on the analysis results. The analysis results and modification approaches' availability were verified by trajectory simulation of one low-speed roll terminal guidance projectile. The modification approaches can provide reference for plateau adaptability of low-speed roll terminal-guidance projectile design and modification.
