Flows in the rocket engine nozzles are numerically analyzed to assess the performance of Thrust Vector Control (TVC) system of fluidic type by using Direct Simulation Monte Carlo (DSMC) method. In the calculation, rigid sphere model is adopted to simulate molecules, and perfectly elastic collisions are assumed. Secondary jet is injected into the flow field through a small port at one side of two-dimensional dual throat nozzle wall. Performance of thrust vector inclination is evaluated and the possibility of hysteresis occurrence is researched.
