Abstract: For a long time the computer programs to analyze static characteristics of liquid propellant rocket engine(LRE)systems were written only for specially assigned engine systems.Such programs were lack of generalization .With the variations of engine system schemes,the system equations and the program must be revised to simulate the new system.In. this paper the principle to set up system equations automatically with computer has been investigated by using nodal method based on system component models.With this software,system simulation can be fulfilled automatically by computer with the input of component parameters and link relationships among components by users.
