A successful proof of concept was performed in FY 2012 integrating the Envision tool for parametric estimates of vehicle mass and the Rapid Response Risk Assessment (R3A) tool for probabilistic risk analysis of vehicle systems. The initial work implemented the capability to assess an Environmental Control and Life Support System (ECLSS), and demonstrated the integrated operation of the tools with the ability to quickly assess the impacts of system trade option selections. Subsequently, additional systems have been added (prop, avionics). Work remains to implement a complete vehicle architecture capability by adding and addressing the trade space of major systems and to develop a capability ready for use by envisioned NASA and JSC projects and organizations such as the Human Spaceflight Architecture Team (HAT).
More »The Product will be a functioning interface tool to perform tradeoffs between risk and mass for an integrated spacecraft architecture, building on the interface tool work successfully completed on Life Support and propulsion systems in the FY12 IR&D effort. The product will provide a two dimensional (mass, reliability) Figure of Merit (FOM) to assess alternative system architectures early in the project design cycle.
