Title: Investigation on secondary gas injection for solid rocket motor based on thrust vector control
Abstract: The complex inner flow-field of secondary gas injection for SRM was numerically simulated by using two-dimensional average Reynolds equations and the κ-e turbulent model.Partial scheme for secondary injection of thrust vector nozzle was preliminarily explored by means of numerical simulation technology.The influences of different injection parameters on flow-field of secondary gas injection and the side force were analyzed and investigated.The results show that the effects of the position of injection hole,the injection angle and the injection total pressure on the side force were coupled with each other,and moderate position of injection hole,countercurrent injection angle and bigger injection total pressure can make the side force and vector angle of the nozzle increase effectively.
