某非圆截面导弹的动态特性分析

Dynamic characteristics of a non-circular missile

利用小扰动飞行动力学方程和参数敏感性分析方法,研究了某非圆截面导弹在典型气动条件下的开环飞行稳定特性.对该导弹在不同静、动导数条件下的飞行稳定性进行了研究,得到了影响系统稳定性的主要因素以及出现较优横侧向稳定性的参数取值区间,这些结论为同类型导弹气动布局和控制系统的设计提供可靠的借鉴.

This paper discussed on the open-loop stability of a non-circular missile, with small-disturbance and parameter sensitivity analysis method. Researches were carried out on the flight stability of this missile at different static and dynamic derivative conditions. From these researches , the main influencing factors of the aircraft stability and parameter sections in which the aircraft have better lateral stability could be found. These results could offer ref- erence for the aerodynamic layout and control system design of missiles of the same type.
