Lightweight, High-Efficiency Cryogenic Liquid Acquisition Device

The Microgravity Testing of Lightweight, Reliable Cryogenic Screen Channel Acquisition Devices with High Expulsion Efficiency project tests a device designed to advance storage and transfer of cryogenic fuels on the lunar surface and in orbit. This lightweight cryogenic liquid acquisition device (LAD) consists of metal mesh screen channels, a screened sump, and guide vanes. The hybrid capillary structures position the residual liquid in the tank to optimum locations to maintain liquid supply for LAD screen surfaces, enhancing expulsion efficiency. The technology has previously completed a parabolic flight campaign, and the experiments performed through these additional flight tests aim to further improve the quality of test data, allow more comprehensive characterization of LAD performance, and promote further technical maturity.
