Feasibility study on future transportation vehicle (termed as reference system) is undergoing at Japan Aerospace Exploration Agency, setting the target on reusable, manned launch vehicles. Two-staged vehicle configuration to low earth orbit is the final target of the current study, while point-to-point high-speed transportation using the same vehicles is also under consideration for near-term application. For long-range point-to-point transportation, system study on a RBCC (Rocket Based Combined Cycle) engine powered vehicle is undergoing, because a very high specific impulse is necessary to make dry-weight to take-off weight ratio reasonable. This vehicle will be used for first stage (termed as booster) of the TSTO-RLV. Performance prediction on the RBCC engine was conducted with varying design parameters especially on embedded rocket engine, to attain higher effective Isp taking airframe drag into account than that of rocket engines. The resulting engine performance was used to estimate the total take-off weight of the vehicle, to show that the vehicle equipping the RBCC engine can be 40% lighter that that equipping ordinary rocket engine with same operation pressure.
