一种新型控制方式的高超音速导弹运动建模

A New Control Mode of Maneuvering Modeling for High Supersonic Speed Missile

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。在牛顿经典力学的基础上,详细推导出高超音速质量矩导弹的动力学模型并对该模型进行了相应的简化,该模型的建立对于研究高超音速导弹提供了一种新型的控制方式,并以此为其工程化提供了必要的理论依据。

Moving center of mass control can realize the maneuvering control of the hypersonic missile. The technique depends on changing the center of mass of hypersonic missile and aerodynamic trim moment,finally can adiust the flying attitude and angle-of-attack. In this paper, it deduces and gives the model of moving center of mass on hypersonic missiles which is based on Newton＇s mechanics. This model will provide necessary theoretical basis for researching engineering design of moving center of mass for hypersonicmissile.
