Integrated Simulation of Synergistic Space Station Subsystems During the Conceptual Design Phase

To allow for the assessment of synergistic subsystem interactions during the conceptual design phase of manned spacecraft and space stations, an existing software tool was improved to permit integrated modeling and simulation of a space station's life support system and attitude and orbit control system. This facilitates early estimation of potential reductions in resupply mass - and life-cycle cost - as well as the assessment of increases in operational flexibility through incorporation of synergisms into the conceptual design. The created interactive tool is based on a user-friendly graphical programming language and can therefore be used by conceptual designers and engineering students alike.
