Since the innovative damage-tolerant isolating adhesive is designed with commercially available building blocks, it will provide a cost-effective and easy-to-apply bonding mechanism between various aerospace structures and materials in space exploration and transportation missions such as orbit transfer vehicles, space power systems, spaceports, spacesuits, lunar habitation systems, etc. A major application is in re-usable launch vehicles (RLV) that have many components with dissimilar mechanical and thermal properties subjected to repeated thermal and mechanical cycles. These components will be difficult to spot-bond via mechanical joints due to interfacial stresses caused by operational cycles. An example is bonding thermal protection system (TPS) and Cryo-insulation materials in integrated insulation designs used for future spacecraft.","description":"Future space exploration projects will expose system components (such as cryogenic systems) to extreme conditions and to a higher number of pressure and temperature cycles, due to long missions and reusable launch vehicle (RLV) designs. High performance materials, such as low-density ceramics, foams, aerogels, composites, metals, and multi-layer insulations (MLI) will be increasingly used. These materials, however, often have poor mechanical strength and damage-tolerance, and are also difficult to bond to each other, due to the extreme operating temperature and pressure cycles and the mismatch between their thermal (expansion) and mechanical properties. The combination of these drawbacks resulted in the catastrophic detachment of foam insulation from the external tank (ET) in Shuttle Columbia, mission STS-107. There is a need for damage-tolerant, \"forgiving\" and multifunctional adhesive technologies for integrating dissimilar materials (such as cryogenic pressurized vessels to insulations), and ensuring reliable, integrated lightweight system designs. To address this need, Applied Analytic Research Inc. has designed innovative cost-effective Isolating Adhesives that are multifunctional, Bond, isolate and protect dissmilar adherends in the same time.","startYear":2011,"startMonth":2,"endYear":2011,"endMonth":9,"statusDescription":"Completed","principalInvestigators":[{"contactId":396458,"canUserEdit":false,"firstName":"Rita","lastName":"Funchion","fullName":"Rita Funchion","fullNameInverted":"Funchion, Rita","primaryEmail":"president@appliedanalytic.com","publicEmail":true,"nacontact":false}],"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}],"projectManagers":[{"contactId":3250933,"canUserEdit":false,"firstName":"Jon","lastName":"Goldsby","fullName":"Jon Goldsby","fullNameInverted":"Goldsby, Jon","primaryEmail":"Jon.C.Goldsby@nasa.gov","publicEmail":true,"nacontact":false},{"contactId":461333,"canUserEdit":false,"firstName":"Theresa","lastName":"Stanley","fullName":"Theresa M Stanley","fullNameInverted":"Stanley, Theresa M","middleInitial":"M","primaryEmail":"theresa.m.stanley@nasa.gov","publicEmail":true,"nacontact":false}],"website":"","libraryItems":[],"transitions":[{"transitionId":65074,"projectId":9192,"transitionDate":"2011-09-01","path":"Closed Out","closeoutDocuments":[{"title":"Final Summary Chart","file":{"fileExtension":"pdf","fileId":305323,"fileName":"195532_09_29_2011_01_52_06","fileSize":81404,"objectId":65074,"objectType":{"lkuCodeId":1841,"code":"TRANSITION_FILES","description":"Transition Files","lkuCodeTypeId":182,"lkuCodeType":{"codeType":"OBJECT_TYPE","description":"Object Type"}},"fileSizeString":"79.5 KB"},"transitionId":65074,"fileId":305323}],"infoText":"Closed out","infoTextExtra":"","dateText":"September 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.
