Six-DOF Modeling and Simulation for Generic Hypersonic Vehicle in Reentry phase

摘要：

　　The purpose of this research is to model a hypersonic vehicle in the pull-up phase and provide an insight into the inherent dynamics.Based on Newtonian mechanics,the theoretical flight dynamic model of the pull-up phase of reentry motion is established; Based on MATLAB/SIMULINK,simulation model for reentry hypersonic vehicle was modeled.Lifting body hypersonic vehicle aerodynamic data is obtained by high-accuracy CFD code which copyright by CAAA.We adopted feedback linearization control theory,pitching angle holding control laws in order to keep maximum lift-drag ratio glider,the six degree of freedom(DOF)simulation validate the control law.The simulation results show some hypersonic flight characteristics,including static unstable,earth radius and rotation effects and high-coupled characteristics.The simulation model and results provide a useful reference for a hypersonic vehicles dynamics analysis,control law design and overall design.
