Abstract
A generalized computer program for analysis of pressure and composition in multiple volume systems has been under development by the National Aeronautics and Space Administration (NASA) since 1976. This paper describes the most recent developments in the program. These improvements include the addition of an X-windows style graphical user interface (GUI), the inclusion of simulations of International Space Station (ISS) Environmental Control and Life Support System (ECLSS) components, the addition of simulation of Shuttle space suits, the addition of an event processor, and the addition of an option for the user to select the volume configuration.
The ARPCS2AT2_STATION computer program was developed by NASA as a tool for analyzing the changes in partial pressures of four gasses (nitrogen, oxygen, carbon dioxide, and water vapor) in interconnected volumes. The current version allows two volume configurations: four volumes in a line, one central volume with four other volumes attached to it. The graphical user interface lets the user select the volume configuration, select which ECLSS components are operating, set initial conditions, create an event list, run the program and look at results in graphs and tabular form.
This paper will describe how the program can be used to support ISS missions by showing how it was used to support the Flight 2A.2B/STS–106.
