Reliable and fast detection of hydrogen leaks is critical to both operational safety and maintenance of propellant quantities for in-space hydrogen systems. Characteristics of the plume formed by a hydrogen leak are unpredictable in low gravity due to lack of buoyancy effects. The proposed hydrogen fiber sensor can detect any flow direction of a hydrogen leak, determine the leak location, and measure hydrogen concentration. The fiber sensor can also detect hydrogen leaks from unexpected locations in space vehicles caused by stress-induced tiny cracks or other various damages. The proposed sensor will have the same fast response speed and high sensitivity in cryogenic environments as in room temperature. Furthermore, the proposed fiber sensor offers several significant advantages, including reconfigurable, lightweight, one feed-through, easy installation, easy maintenance, and capability of working in radiation harsh environments. In Phase 1, feasibility work has been performed. In Phase 2, prototypes of the proposed hydrogen fiber sensor will be produced for field trial and be prepared for commercialization in Phase 3.","startYear":2009,"startMonth":9,"endYear":2011,"endMonth":6,"statusDescription":"Completed","programDirectors":[{"contactId":206378,"canUserEdit":false,"firstName":"Jason","lastName":"Kessler","fullName":"Jason L Kessler","fullNameInverted":"Kessler, Jason L","middleInitial":"L","primaryEmail":"jason.l.kessler@nasa.gov","publicEmail":true,"nacontact":false}],"programExecutives":[{"contactId":215154,"canUserEdit":false,"firstName":"Jennifer","lastName":"Gustetic","fullName":"Jennifer L Gustetic","fullNameInverted":"Gustetic, Jennifer L","middleInitial":"L","primaryEmail":"jennifer.l.gustetic@nasa.gov","publicEmail":true,"nacontact":false}],"programManagers":[{"contactId":62051,"canUserEdit":false,"firstName":"Carlos","lastName":"Torrez","fullName":"Carlos Torrez","fullNameInverted":"Torrez, Carlos","primaryEmail":"carlos.torrez@nasa.gov","publicEmail":true,"nacontact":false}],"website":"","libraryItems":[],"transitions":[{"transitionId":438,"projectId":7944,"transitionDate":"2011-06-01","path":"Closed Out","infoText":"Closed out","infoTextExtra":"","dateText":"June 2011"}],"responsibleMd":{"acronym":"STMD","canUserEdit":false,"city":"","external":false,"linkCount":0,"organizationId":4875,"organizationName":"Space Technology Mission Directorate","organizationType":"NASA_Mission_Directorate","naorganization":false,"organizationTypePretty":"NASA Mission Directorate"},"program":{"acronym":"SBIR/STTR","active":true,"description":"
The NASA SBIR and STTR programs fund the research, development, and demonstration of innovative technologies that fulfill NASA needs as described in the annual Solicitations and have significant potential for successful commercialization. If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
