| Abstract: | Based on the dynamic mathematical model of gas system in integral bipropellant propulsion sys- tem, the response characteristic of gas system during working process including starting up and coorking is simulated. The simulation results show that the temperature of gas system varies little around the stead- y-state point for one-dimensional ideal gas adiabatic. Then, by eatablishing, the state space models （SSM） of gas system. The effects of main parameters on gas system stability are obtained. Meanwhile, the method that can improve the dynamic characteristic of gas system is also presented. |
