Completed TRL 5 (started at 3, targeting 6)
This project will design, build, demonstrate a 150W/ 90 K RTB cryocooler having a specific mass of 0.4 kg/W and a specific power requirement of 8.0 W/W. Project objectives include:
1. Assemble and test the 150W 90K RTB Cryocooler compressors.
2. Complete build of the 150W 90K RTB Cryocooler.
3. Conduct acceptance testing of the 150W 90K RTB Cryocooler to validate system performance in an operational environment.
4. Conduct environmental vibration testing on cryocooler system.
5. Deliver the validated cryocooler system to NASA.
High Capacity Cryocoolers are deemed to be an enabling technology for the long-duration storage of cryogens. The Reverse Turbo-Brayton (RTB) cycle cryocooler is recognized as having significant maturity as well as the ability to meet performance demands.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 5) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
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.
