The stored hydrogen and oxygen are also usable as rocket propellants, and furthermore, the water and oxygen are available for the life support system at emergencies of manned space activities. Our study is to design a propulsion & power system originated from safe and non-toxic water that is one of the simplest compound on Earth, and to perform ground-based experimental testing toward a sub-scale model. The performance verification in the Space Station is necessary for the end but based upon the fundamental researches so far, we estimate the flight performances from testing such as optimization of single-cell performance, configuration of electrolysis and fuel-cell (reversible single cell or two separate cells), rocket engine combustion in vacuum, overall systems checkout, and weightlessness simulation (on the tri-axially relatable test-stand)., 資料番号: AA0049121014}, pages = {64--68}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {水サイクル宇宙推進システムの実証モデル}, year = {2006} }
