This paper will detail the results and finding of an investigation to identify key cryogenic fluid management (CFM) techonologies to reseach for the NASA space launch initative (SLI). The SLI Propulsion Project Office identified CFM as potential technology gap and assembled a team of NASA researchers to validate their conclusion. The purpose of this investigation was to assist the SLI program in selecting research opportunities in forth coming efforts to mitigate valid program risk. Technical experts were selected from NASA Glenn and NASA Marshall from the NASA CFM working group. The NASA CFM Working Group has provided previously insight for prioritizing many test objectives regarding long-term storage of sub-critical LH2 for upperstages, deep space/planetary missions, and on-orbit depot applications. The assembled team visited key SLI contractors to accomplish the following goals: CFM Technology Elements discussed included;Zero-G Pressure Control Without Propellant Settling All SLI Contractors verified a CFM technology gap exists. All SLI Contractors either had cryogenic propellants baselined or as their first option in their 2nd Generation architecture studies. From information gathered the Cryogenic Working Group (CWG) has developed technical plan for SLI to address the issuses raised and mature CFM for use on a operational next generation space transportation system. This paper will detail the technical assessments presented by the CWG team, the SLI contractors response, the use of CFM in SLI architectures, as well as the current state of research efforts and plans for continued work.
