A conceptual study is conducted of fly-back boosters as the proposed candidates for future transportation systems which can be realized in the near future. System design requirements such as policy and scope of design study are reviewed. Conceptual design of the body such as the design flow and design conditions, optimization of performance sharing between fly-back boosters and upper-stage rockets, body configurations, weight estimates and weight balance of the body, trade-off of candidate optimized configurations, and flight profiles is conducted. Baselines and candidates of configuration, required performance, weights of engines for cruising, and dimensions of the body are presented. Results of body weight analyses, and flight profiles are also presented.
