一种新型高超音速导弹的控制模式研究

高超音速导弹的质量矩控制是通过移动导弹内部滑动质量块的位置,使整个导弹的质量中心产生偏移,并利用气动力相对于质心的力矩改变导弹的飞行姿态和攻角,最终实现导弹机动控制的一种控制方式。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。

Researching Control Mode on A New Hypersonic Missile

Mass moment control is a new control way,and it bases on changing the mass center of missile through moving the masses which is inside the missile,at same time,flight attitude and attack-angle can be adjusted by aerodynamic moment,so it usually can be a control way to realize the maneuvering flight of hypersonic missiles.Supposing that the researching object was a reentry warhead,so it gave appropriate control mode for mass moment warhead,which was based on that the dynamic equations of mass moment controlled reentry warhead was derived in detail and variational orderliness of warhead's characteristic about the equations,velocity and aerodynamic parameter was analyzed in course of reentry phase.This control mode would provide necessary theoretical basis for design of mass moment control coefficient for hypersonic missile.
