基幹ロケット上段推進系の発展と国際有人探査への貢献 －極低温軌道間輸送機の研究開発－

第57回宇宙科学技術連合講演会（2013年10月9日-11日. 米子コンベンションセンター（BiG SHiP）), 米子市, 鳥取県
Upper stages of H-IIA and H-IIB use LOX/LH2 as a propellant and achieve high performance and reliability. Utilizingthe experiences of cryogenic propellant management, the upper stage of H-IIA is now being upgraded for more efficientmass transfer. The propulsion system development is one of the most critical issues for the H-IIA Upgrade, and willsucceed CPS, Cryogenic Propulsion Stage, which is an element of the international exploration architecture for thein-space orbital transfer. Currently, CPS was scaled up to DUUS, Dual Use Upper Stage, and JAXA is now conducting acollaborative study with NASA. It is necessary to improve understanding of cryogenic propellant management to developDUUS, hence, JAXA focuses on not only vehicle development but also basic researches with universities and industries.
