Based on the development of large liquid rocket engines

a universal system organization capability approach was presented according to the thought of modularization modeling and the requirements of general simulation.Mathematical model in the module was stored in the form of code text;and the operator could add models or expand block library from the operator interface.This paper described the approach of realizing such software architecture.In Microsoft Visual Studio 6.0 platform

C++ language was utilized to develop the simulation software and implement visual modeling based on MFC(Microsoft Foundation Classes) document view architecture

and finally a particular transient simulation of liquid propellant rocket engine was fulfilled.By comparing the results with the test run curve

the feasibility and correctness by adopting the simulation method was verified primarily.The researchers can carry out expediently dynamic process simulation in other liquid rocket engines.
