In-Space Cryogenic VOST Connect/Disconnect, Phase I

Completed

Description

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.

How to get involved

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
