In order to improve the accuracy of gas generator flow regulation for solid fuel ramjet, a pressure control system for gas generator was researched. Mathematical models of gas generator and air serve system were built, and the characteristics of pressure control system for gas generator were analyzed. The flow control system was simulated and validated by tsemi-physical simulation system, and the curve of the pressure changing in the gas generator was achieved. The result of the experiment shows that the pressure control system is one which changes slowly, and its parameters are time-variation.
