Simulation modeling in designing regenerative life support systems for manned spacecraft

The paper concentrates on the discussion of using simulation modeling for analysis of technical requirements for the regenerative life support systems of manned spacecraft in the design phase. Defined is a standard set of target indicators (technical requirements) for the regenerative life support systems. The structure and purpose of the simulation functional model of the integrated regeneration atmosphere revitalization system of the manned spacecraft are considered. Formalized descriptions of processes occurring in the carbon dioxide hydrogenation reactor are proposed, computational experiments using the simulation model are carried out. A comparative analysis of experimentally obtained data with the results of computational experiments is presented, and the optimal values of input parameters of the hydrogenation reactor operation are determined.
