The Resource Tracking Model (RTM) integrates the functions of all the vehicle components that significantly affect the processing and recovery of water during simulated missions. The approach used in developing the RTM enables its use as part of a complete vehicle simulation for real-time mission studies. Performance data for the components in the RTM are focused on water processing. The data provided to the model have been based on the most recent information available regarding the technology of the component. This paper will describe the process of defining the RLS system to be modeled, the way the modeling environment was selected, and how the model has been implemented. Results showing how the RLS components exchange water are provided in a test case.application/pdfengPresentation
