姿控发动机布局方式研究

摘要

大气层外飞行器的姿态控制一般采用姿控发动机的喷气控制,姿控发动机的布局直接影响到姿态控制的效果.对国内外飞行器的姿控发动机布局的发展情况进行了综述,并从工程实践的角度出发,讨论了姿控发动机在布局时需要考虑的一些矛盾因素.在此基础上,提出了利用耦合解决这些矛盾的思路以及姿控发动机布局的3条基本原则.仿真结果表明利用耦合改善了姿态控制效果.%The attitude control of the exoatmosphere vehicle is usually carried out by the attitude control thrusters (ACT). And the configuration of ACT has great influence on the control effect. A summary of the development of the research on ACT is given. Some contradictory factors while designing ACT configuration is discussed in the view of engineering practice. Then, an idea of using coupling to solve the problem is put forward and three basic principles of ACT configuration are presented. Simulation result indicates that the ACT effect is improved by using coupling.
