The flight of spaceplane is always under accelarating in the assent way and always under decelerating in the desent way and yet cruising in the return way. Besides, its flight envelope is considerably wider than that of airplane. Thus the integrated design method is required to build the best transportation system optimized taking into account the propulsion system and the airframe under the entire flight conditions. In this paper its shown an optimization method on TSTO spaceplane system. Genetic algorithm (GA) was applied to optimize design parameters of engine, airframe, and trajectory simultaneously. Several types of engine were quantitatively compared using payload ratio as an evaluating function. From a Viewpoint of the relation between performance and weight, it was concluded that the precooled turbojet is the most promising engine for TSTO among Turbine Based Combined Cycle (TBCC) engines.
