Using the numerical analyzing method, this article studied on the problem of the thrust-vectoring flow field. It gave the homologous mathematics-physics equations, described the relevant geometrical model boundary condition in details and then offered a appropriate calculating model. According to the two combustion chamber conditions and different sizes of et vanes, the article also calculated the combination motor and jet et vane. The result presented the flowing status of thrust-vectoring motor jets withjet et indicated that the established computation model is practically effective. Therefore, this research would instructive reference straight for the structure design of thrust-vectoring motor and jet et vane. motor jet , grid and kinds of model of vanes and provide a
