Gravity Independent Compressor, Phase I

We propose to develop and demonstrate a small, gravity independent, vapor compression refrigeration system using a linear motor compressor which effectively addresses the efficiency, lubrication, scalability, and/or longevity issues limiting current space flight refrigeration systems. Unlike previous and currently used thermoelectric, Stirling, oil-free reciprocating and diaphragm compressor systems, the linear compressor will provide very high efficiency, excellent capacity modulation, nearly unlimited scalability, and very long life all due to the hydrostatic bearing of the linear compressor and use of the reverse-Rankine cycle. The linear can also readily be developed as a single unit two-stage compressor for higher lift applications.

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.
