Project Objective
This project is performing proof of concept studies to assess a proposed novel vibration mitigation devise, a multidirectional particle damper.
Project Description
The results of this project, which will prominently feature physical testing, will be data and a final report on the effectiveness and feasibility of the ring particle damper. It is expected that these results will encourage future development and investment to bring this system to commercialization. It is expected that the subject devise will be applicable to multiple applications. Specifically, any system that has to endure vibrations in multiple directions simultaneously.
Project Results and Conclusions
This project received funding in July of 2024 and was originally expected near the beginning of FY24. Due to the date when funding was received, efforts initiating were very delayed. Hence, no results are yet available. A 12 month NCE was granted. The project end date is now 02/20/26.
Status: The planned Test Article (TA) has been designed and fabricated. Initial tests have been run to check out the TA and the overall test system. TA design mods have been made and implemented.
A benefits from this project is a vibration mitigation technology applicable to vibration environments in multiple directions simultaneously. this is applicable to any mechanical system or structure that is designed to sustain simultaneous multi directional vibrations. It is also envisioned as applicable to mitigating radial modes of vibration ("breathing modes") of launch vehicles.
Listed on TechPort itself — the most direct way to ask about this specific project.
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.
