摘要
本文讨论了再入机动飞行器三自由度和六自由度仿真和分析。三自由度仿真研究了再入机动飞行器的导引规律和减速控制规律,证明了其合理性,且精度是满足要求的。而六自由度仿真说明了飞行器再入过程中虽然有静稳定和静不稳定交替出现的飞行状态,且动压变化大,如控制系统和制导方法设计良好。
In the paper,the simulation of three & six degrees of freedom of maneuverable reentry vehicle is described and analysed The guidance law and velocity control of maneu verable reentry vehicle are studed by means of simulation of three degrees of freedom,and its reasonableness is testified Moreover,the accuracy of trajectory impact under various disturbances is acceptable And by simulation and analysis of six degrees of freedom,it is proved that if the adequate control system and guidance scheme are designed fine,the effectiveness is also good like above,though the flight state of vehicle varies between static stability and unstatic one and the dynamic pressure changes in large scope
