To achieve the full potential of PMD/LAD technology for high performance space exploration missions mass reduction is essential. Screen channel acquisition devices are an interesting approach for future spacecraft using cryogenic propellants. However, traditional manufacturing techniques (i.e. metal-based) are heavy and have reliability issues. To achieve desired mass savings and screen reliability, GTL proposes to develop a high-performance PMD/LAD using advanced composite materials technology based upon their innovative BHL™ composite cryotank technology. GTL’s BHL technology provides a 75% mass savings compared to equivalent state-of-the-art metal cryotanks. In this Phase I effort, GTL will design and fabricate screen samples. These screens will be cryogenically thermally cycled and tested for their performance and reliability. A proof-of-concept BHL composite channel arm will be designed and fabricated to demonstrate the manufacturing process and provide mass data. The Phase I effort will conclude with an examination of integration into GTL’s high performance 4 ft diameter BHL spherical cryotank. During the phase II effort, a developmental version of the composite PMD/LAD will be fabricated and tested to verify its performance. The Phase II effort will conclude with the fabrication of a prototype sherical cryotank with an integral composite PMD/LAD. Operational testing will advance the technology readiness to TRL 6, which will open the way for the technology to be used in upcoming space exploration missions.
