The influences of different factors on the flow characteristics of the internal flow field, the motor performance parameters and the force on the pintle were studied, and the control performance of the pintle motor was explored. Based on the method of numerical simulation, the flow field in nozzle under different pintle profiles and pintle tail groove designs was calculated and studied. The results showed that the thrust adjustment range of pintle variable thrust solid rocket motor was large, and the force variation of pintle was also large. The change of pintle profile had no significant effect on pintle load, and the maximum load decreased 28%. The design of the tail groove of the pintle can balance the pintle load to a large extent, and the maximum load was reduced by 56%. The design of the guide groove of the valve body of the pintle had a significant effect on reducing the force on the pintle, and the maximum load decreased 91%, which greatly enhanced the control performance of the pintle variable thrust solid rocket motor.
