| Abstract: | The stifffness analysis for the exit cone of solid rocket nozzle using the finite element method is conducted. Based on the stiffness analysis,optimization about the direction for the direction for the actuating force of the thrust vector control (TVC) system is discussed. The optimum results for a solid rocket motor nozzle exit cone are obtained. |
