| 摘 要： | 针对旋转导弹在飞行过程中，由于俯仰和偏航通道的气动交联、惯性交联和控制交联而形成的锥形运动对弹体稳定性的影响,在对锥形运动进行动力学建模的基础上，利用劳斯定理分析了旋转导弹锥形运动的稳定性条件，揭示了锥形运动稳定性与飞行状态、气动特性以及弹旋速度的关系，并针对旋转导弹做锥形运动时的角运动特性进行了仿真。仿真结果验证了该稳定性条件的可行性和正确性，研究结果为旋转导弹总体设计及制导控制系统设计提供了参考。

| Abstract: | In view of the influence of conical motion on rotating missile caused by aerodynamic crosslinking, inertial crosslinking and control crosslinking in pitch and yaw in the course of flight, dynamic modeling of conical motion and analysis stability of conical motion of rotating missile by using Routh theorem reveal the relationship between the stability of conical motion and flight state, aerodynamic characteristics and rotation speed of missile. Simulate the angular motion characteristics of conical motion on rotating missile. Simulation proves the feasibility and correctness of the method to judge the stability, which offers a reference for the overall design of rotating missile and the design of guidance and control system. |
