The vector control research of top attack anti-tank missile are only focused on jet vane control.Aiming at this problem,the aerodynamic model under the joint action of aerodynamics and jet action was put forward in this paper,which proposing mathematical models of 7stages of typical trajectory for the first time.These models expressed trajectory design proposals and mechanics models of all stages,which were proved to be accurate and reliable by simulation on Simulink,and by wind tunnel test and lauching test as well.
