高超音速导弹的新型控制模式研究

弹头变质心机动控制是通过移动弹头的质心位置,利用气动配平力矩改变弹头的飞行姿态和攻角,从而可实现弹头机动控制.以弹头为例,在推导出质量矩弹头的动力学方程基础上,通过分析其方程组的特点并结合弹头再入过程中的气动、速度等参数变化规律,给出了质量矩弹头再入过程中宜采用的控制模式,为其控制律的设计提供了必要的理论参考.

A New Control Method's Researching of High Supersonic Speed Missile

Moving center of mass control can realize the maneuver control of the hypersonic missile.The technique depends on chan- ging the center of mass of hypersonic aircraft and aerodynamic trim moment,finally can adjust the flying attitude and angle-of-at- tack.Supposing that the researching object is reentry warhead,so it gives appropriate control mode for mass moment warhead,which is based on that the dynamic equations of mass moment controlled reentry warhead is derived and variational orderliness of warhead' s characteristic about the equations,velocity and aerodynamic parameter is analyzed in course of reentry phase.This control mode will provide necessary theoretical basis for design of mass moment control coefficient for hypersonic missile.
