Abstract: A versatile numerical simulation method based on the graph theory and object-oriented technique is presented for the space propulsion systems with liquid propellant. The motivation for developing the method is to provide the conceptual-level space propulsion systems designer with a tool capable of providing "quick-look" answers to systems traditional studies and checking. According to the method, a software written in C++ was developed. It simulated the performance of sorts of space propulsion systems. The results of simulation agree well with available theortical data. Meanwhile, the software displays very well versatile capability.
