Mated Air Interchange System Performance Model for Space Shuttle/MIR-Station/Spacelab Docking Mission

A multi-element fixed control volume air interchange system performance computer model was developed to evaluate the atmospheric characteristics within each crew chamber on the mated Orbiter/Mir-Station/Spacelab. This computer model was utilized to analyze and determine the Orbiter airflow supply capabilities, and to develop mated air interchange system design limitations and requirements. The results from this performance model were also used to predict possible air interchange system operating constraints, such as occupancy limitations in each chamber, during the Orbiter/Mir-Station docking mission. With minor modification, this model can also be used as a predictive tool for the analysis of future International Space Station Alpha (ISSA) mated air interchange system performance during the Orbiter/ISSA docking mission.
