Completed TRL 3 (started at 2, targeting 3)
Applying add on passive damping systems has no t (based on a literature search) been attempted in cubesat/smallsat design. If successful this proposal could contribute to that industry and alter the way cubesats/smallsats are designed. The major objective is to demonstrate through analysis and test the realized damping of the system and weight saving associated with the increase in damping. Currently, typical cubesats pursue vibration isolation systems which can be costly and in addition the design of which must be controlled by the cubesat rather than the launch vehicle. If successful, the design approach developed in this proposal can be applied to new smallsats, such as Solar Cruiser. It is also extensible to other structure looking to reduce dynamic response.
Cubesats and smallsats respond to launch vehicle dynamic loads causing heavier structure and extreme test environments for on-board components. Add on passive damping will mitigate structural response, reducing required weight and minimize component dynamic loads. This project will show that typical smallsat and cubesat damping can be taken from around 1% to roughly 6%.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 3) — 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.
