Summary:

The G198A generalized environmental control and life support system (ECLSS) simulation computer program has a library of ECLSS component and subsystem subroutines that can be used to model the complexity of planned ECLSS's for advanced manned spacecraft. The G189A program has successfully provided the necessary mathematical modeling functions for the Skylab and the Space Shuttle orbiter. This paper presents developments at Rockwell International concerning the preparation of the user-friendly computer program (PrepG189) for facilitating G189A program schematics and input data preparation. The two major subprograms in PrepG189 are the schematic processor and the panel processor. The program is operated on a VAX computer terminal. A high level of maneuverability has been achieved in moving between the subordinate portions of the program that participate in numerical data and schematic preparation. The new input data preparation feature of PrepG189 greatly improves efficiency (reduces errors) in specifying and updating ECLSS flow stream connections between pairs of components, subsystems, and interfaces. In addition to the new developments and features of the PrepG189 program, this paper also presents an example of advanced manned spacecraft ECLSS simulation illustrating input and output data and schematics prepared through the use of the PrepG189 program
