Abstract: A numerical model is developed to simulate the transient processes of a pulsatingengine system with multiple thrust chambers. The simulating result of working processes of a spaceengine system shows that, for different numbers, or types of working thrust chambers, single thrustchamber has different response characteristics. And, the comparison between testing data andsimulating results of the same rocket engines shows the correctness of this model.

Key words: Attitude control rocket engine;Thrust control;Dynamic response;Numerical simulation
