TECHNICAL ABSTRACT (LIMIT 200 WORDS)
A novel cryogenic coupling will be designed and modeled. Intended for in-space use at cryogenic propellant depots, the coupling is 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 flow measurements, and robotic control are possible.

POTENTIAL NASA COMMERCIAL APPLICATIONS (LIMIT 100 WORDS)
In-space cryogenic connect/disconnect.
Safety disconnects.
Earth-based gantry quick-disconnects.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (LIMIT 100 WORDS)
In-flight refueling, transfer of toxic/hazardous materials, thermally efficient transfer of LNG.
