Study of Advanced System for Air Revitalization

To support sustained manned activities in an enclosed environment in space vehicles such as the Space Station (SS), a respirable air supply system is essential and optimization should be aimed at in the design of such a system.

For cabin air revitalization, it is indispensable to remove carbon dioxide (CO2) and other gaseous contaminants generated from crew and/or non-metalic materials to prevent them from accumulating.

In addition to the above functions, oxygen (O2) recovery function using trapped CO2 is indispensable for the Air Revitalization System (ARS) because a reduction of resupply materials from ground is strictly required. This paper presents and an outline of a feasibility study of the ARS in which system optimization is made.
