Turbo-Brayton Power Converter for Spaceflight Applications

Future NASA space missions require advanced systems to convert thermal energy into electric power. These systems must be reliable, efficient, and lightweight. In response, we propose to develop a turbo-Brayton power converter with high efficiency and specific power. The converter will use gas bearings to provide reliable, maintenance-free, long-life operation. It will also consist of discrete components that can be packaged to fit optimally with other subsystems, and its continuous gas flow can communicate directly with remote heat sources and heat rejection surfaces without ancillary heat transfer components and intermediate flow loops. Creare is well suited to succeed because we have a long history of developing advanced turbomachines, heat exchangers, and Brayton systems for challenging spaceflight applications. We completed detailed analyses, trade studies, fabrication trials, and preliminary designs for the components and converter assembly during Phase I, and we now plan to fabricate and test a breadboard converter during Phase II.

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.
