基于变质心控制导弹的运动分析

导弹变质心机动控制通过改变弹头的质心,利用气动配平力矩改变弹头飞行姿态和攻角,从而实现导弹机动控制.本文首次详细推导了基于变质心控制导弹的空间六自由度的动力学方程,并建立了一套完整的仿真系统,针对导弹在垂直平面内运动情况进行仿真,为深入探讨变质心控制弹头的控制机理奠定基础.

Motion Analysis on Moving Center of Mass Controlled Missile

Moving center of mass control for missile is used to implement the maneuver control over the missile and to promote the end-guidance accuracy by changing the center of mass of ballistic missile and aerodynamic trim torque, so as to adjust the flying attitude and angle-of-attack. In this paper, it is the first time that the six degrees of freedom dynamic equation of the moving center of mass controlled missile is derived in detail and a complete six degrees of freedom simulation system is established. A kind of simulation about the missile attitude confined to vertical plane is performed in order to lay a foundation on developing the control mechanism over the moving center of mass controlled missile.
