General simulation on modularization of liquid rocket engine

Based on the development of large liquid rocket engines, according to the thought of modularization modeling and the requirements of general simulation, a universal and system organizational capabilities approach was presented. Mathematical model in the form of the module was stored inside the code text, and just from the operator interface, operator added models or expand block library. This paper described the approach of realizing such software architecture. In VC6.0 plat-form utilizing C++ language to develop the simulation software, implemented Visual Modeling based on MFC document view architecture and finally fulfilling a particular transient simulation of liquid propellant rocket engine. By comparing the results with the test run curve, the feasibility and correctness by adopting of simulation method was verified primarily. The researchers can carry out expediently dynamic process simulation in other liquid engines.
