A GENERAL MODULAR METHOD FOR STATIC SIMULATION OF LIQUID ROCKET ENGINE

A new modular method is proposed for static simulation of liquid rocket engine.The modules of the engine system are calculated iteratively in a predetermined sequence,and a modified Newton method is used to find the unknown variables of the system.This method has generality for the static simulatin of liquid rocket engine,and it can be applied to analyzing the effects of the disturbances on the performance of the engine.The number of the system unknown variables can be cut down by using this method,and the solution can be found quickly and accurately.The program based on the method is realized by the object-oriented programming.The static simulation results of a liquid rocket engine are obtained from this program.
