【Abstract】 To our best knowledge, we are the first in China to establish the mathematical model needed for controlling the vector angle of axisymmetric thrust vectoring nozzle. Before establishing this model, preparatory research work must be done. Section 1 uses A. Jameson′s finite volume method to calculate the inner flow field and performance parameters of axisymmetric thrust vectoring nozzle described in Ref., and in Figs. 1 through 4 compares the calculated results with test data given in Ref.. Section 2 discusses another part of our preparatory research; it also uses Jameson’s finite volume method to calculate performance parameters for a certain type of Chinese axisymmetric thrust vectoring nozzle. Section 2 also discusses the relationships among performance parameters, geometric configuration parameters and boundary conditions. Finally, using the above mentioned relationships, section 3 establishes the mathematical model needed for controlling the vector angle of axisymmetric thrust vectoring nozzle.更多还原
