G189 Computer Program Modeling of Environmental Control and Life Support Systems for the Space Station 871427

The initial development and subsequent evolution of the environmental control and life support system (ECLSS) for the manned Space Station requires a numerical modeling computer program that can accurately simulate theThe G189 program has successfully provided this modeling function for the Skylab refrigeration system and for the environmental control system (ECS) in the Space Shuttle orbiter. Recent developments at Rockwell International are presented here for a user friendly computer program for facilitating G1S9 program input data preparation, and a Space Station ECLSS model simulation.For this paper, a candidate Space Station ECLSS configuration was modeled. Functions modeled included O2 generation, CO2 removal, CO2 reduction, water recovery, cabin atmosphere composition and pressure control, cabin temperature and humidity control, and trace contaminant control.
