In this research, the liquid propulsion system analysis program is proposed as a module program of the space launch vehicle design and analysis program. It is organized to predict performance of propulsion system using representative parameters which affect a launch vehicle. Major components and their inter-relationship are arranged and using given design variables, it obtains thrust, specific impulse, weight and so on. Through the comparison with parameters of a real launch vehicle, it is validated that the developed program can be used in preliminary design of launch vehicle system with low fidelity analysis.
