摘要

Life-cycle-cost estimation at the conceptual design phase is one of the most essential items to assess the feasibility of various future space transportation systems and to establish the technical scenarios for them. Multidisciplinary optimization involving some subroutines as represented by cost estimation is strongly required to assess the reasonable and feasible future space transportation systems. "Systems Evaluation and Analysis Tool (SEAT)" is under development in JAXA. This study describes TRANSCOST 7.1 based cost estimation compares with the life-cycle-costs of some rocket based vehicle concepts relatively, and discusses the effectiveness and limitations associated with this estimation. "TYPE-R" vehicle propelled by thrust controllable liquid rocket engine as RL V has the advantages in the life-cycle-cost reduction and growth in the number of flights. Even if any engine safely shuts down at a certain time during the mission, this vehicle has the potential performance for abort mode operation that the remaining engines can be powered up to full thrust level.
