摘要
水平侧向力会导致自旋导弹不稳定飞行.对准弹体坐标系中横向运动非线性模型进行了线性化,利用劳斯稳定判据得到侧向力作用下的稳定性条件,分析了侧向力作用导致的进动和章动不稳定运动.与Lloyd研究结果进行了对比,证明本模型和方法的正确性.本方法比文献[2]方法具有更好的通用性.
Horizontal side force may cause instability of spinning missile. The nonlinear transverse equation in quasi-body coordinates is linearized. Condition of stability under the action of side force is obtained by Routh stability criterion. Precessional and nutational motions are simulated. The model and analysis methods are proved to be right compared with Lloyed＇s work. The method has better generality than that of reference 2.
