Abstract: The authors summary the programs for thrust vector control systems and emphatically introduce the calculating idea and results for movable nozzles and fluid secondary injection. The influence of the inertia force due to missile deflection should be regarded in the flow calculation of movable nozzles. The wall pressure distortion illustrates that there is a three-dimensional flow in nozzles. The hinge force should be minimized in design of movable nozzles. The side force of the fluid secondary injection is calculated with "equivalent existence model" and the solution of the explosion wave. Seeking for the engineering applicable calculation method is the main goal nowadays. As such, some calculating methods have not be perfect yet. The particles of Al2O3 in the gas flow are not regarded in the calculations presented in this paper.
