Circulation precooling method is commonly used in Chinese new generation launch vehicles for the purposes of saving precooling propellant, simplifying processes before launching, and enhancing the safety coefficient of precooling. This research focuses on mechanism of circulation precooling and the influence factors. A new simulation system of circulation precooling based on AMESim has been developed and the natural circulation precooling system of cryogenic launch vehicle is analyzed in details by applying this model. A good agreement is achieved between the simulation results and published experiment data.
