为研究某型末制导炮弹惯性飞行过程的稳定性，建立该炮弹在惯导飞行阶段有控弹道攻角运动方程。基于该攻角运动方程，求解方程特征根推导出末制导炮弹自由运动的稳定性条件，并给出舵片偏转控制力对弹体强迫作用的解，分别讨论了影响自由运动和受迫运动稳定性的因素。分析结果表明，惯性飞行过程中，舵面参数以及弹丸转动角速度是影响飞行稳定的主要因素，舵片偏转过程与弹丸共振条件无关。

In order to study the stability of terminally guided shell during inertial flight,the angu-lar motion of controllable traj ectory is investigated.Based on the general angular motion,flight stability condition is fixed and the canards deflexion imposed on the body is obtained through the special solution of angular motion.The main relative factor of stability of inertial flight is dis-cussed.The results indicate that canards parameters and angular velocity are main factors which influence the dynamic stability,and canards deflexion has no relationship to the sympathetic vibra-tion condition of traj ectory body.
