In-Space Cryogenic VOST Connect/Disconnect, Phase II

Two novel cryogenic couplings will be designed, fabricated and tested. Intended for in-space use at cryogenic propellant depots, the couplings are based on patented Venturi-Offset Technology (VOST) and will provide small fluid and heat leakage at high flows with a low pressure drop. Entirely mechanical, insertion opens the passage, removal closes the passage. Mating force and alignment requirements are small. With only eight major parts, reliability is high and mass is low. Redundant seals, integrated health measurements, and robotic control are possible.
