Ultra-Low Weight Hot Gas Valve for Long Duration SDACS

VTS has developed, through the MDA SBIR program, an advancedattitude control system (ACS) design enabled by a new Hot Gas Valve technology. The design incorporates innovative materials that have balanced structural and thermal properties resulting in improved Hot Gas Valve operation duration. VTS is proposing, during this SBIR, continued spiral development of the HGV technology from the TRL-5 matured insulated metallic housing design to a completely composite HGV design. The new all composite HGV design eliminates basic metallic pressure housing temperature limitations and thus enables a hot running design that can operate longerthan the demonstrated HGV technology while reducing overall HGV Weight by 20%.(Approved for Public Release 15-MDA-8482 (17 November 15))
