Simulation technology is one of the main methods to study the dynamic characteristics of liquid rocket engines. The research progress of dynamic characteristics of liquid propellant rocket engine at home and abroad is summarized. The research progress of simulation technology is divided into three stages: special simulation program phase, general simulation software phase and multi-disciplinary co-simulation phase. The progress of each phase is summarized and reviewed, and the main characteristics of simulation technology in each phase are analyzed. On the basis of summarizing the research progress, the author puts forward some tentative ideas for the future development of engine dynamic simulation technology.
