Autonomous, Cryogenic Leak Detector for Improving Launch Site Operations, Phase II
Completed
Description
Spaceports, spacecrafts for planetary missions, future projects on the moon and mars -- they all need to monitor mission critical propellants. This project established the feasibility of a tapered optical fiber-based sensor (TOFS) that can be fitted into narrow orifices of plumbing junctions to detect the leakage of cryogenic fluids such as hydrogen. Complete reversibility and response/recovery time of less than 30 seconds for the hydrogen sensor were demonstrated in Phase I. Scanning electron microscope (SEM) images confirmed that the sensor suffered no degradation upon soaking in liquid nitrogen (LN2, 77 K). Tests with LH2 will be conducted in Phase II. The underlying sensor technology will support NASA goal of reducing vehicle and payload cost, and increase safety of operations by measuring hydrogen in real-time and in situ. A prototype device will be engineered, field-tested and delivered to NASA in Phase II establishing technical maturity approaching TRL 6. InnoSense LLC has received a strong endorsement letter from a major Aerospace company in support of the project. InnoSense LLC has also received Phase III follow-on funding commitment totaling $500,000 from commercialization partners. An engineering team having 80 person-years of cumulative experience in developing commercially viable products has been assembled for this project.

How to get involved
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.
