| 摘 要： | 变质心控制作为一种新颖的控制方式,可克服传统再入飞行器气动舵等控制方案存在的舵面烧灼等弊端,它通过主动移动飞行器内部若干个质量块,可以有效调整飞行器的姿态并实现飞行器的姿态和机动控制.本文在推导变质心再入飞行器动力学方程的基础上,对该动力学方程进行了必要的简化,从而得到了变质心再入飞行器纵平面内的动力学和运动学方程,并计算得到质量块不同行程下飞行器可产生的法向过载大小.本文的研究对于变质心再入飞行器控制系统的设计提供了必要的理论参考依据.

| Abstract: | Moving centroid control for reentry vehicles is used to realize the maneuvering control by changing the center of mass of reentry vehicles and aerodynamic trim torque,so as to adjust the flying attitude and angle of attack.The disadvantages of traditional pneumatic actuator control for reentry vehicles are overcome including rudder surface ablation when flied at high speeds.Based on the foundation of building up dynamic equations of the moving centroid,the dynamic equations are simplified,and the dynamic an... |
