Creare has developed flexible radiators that are extremely lightweight, stowable in small volumes, and deployable with small forces, but are limited by materials to temperatures below 350 K. These novel radiators incorporate integral micrometeorite protection. Our innovation is a material combination and fabrication method that produces radiator panels with low weight, high fin efficiency, and excellent strength at temperatures. Our goal is to provide a radiator technology based on prior technologies and provides a major advancement toward NASA's goals for light weight and high temperature operation in advanced radiators. The innovative approach does not require development of new materials, simply refinement of processes to join standard metal tubes and foils in the configuration desired. In Phase I we proved the feasibility of the concept and demonstrated the ability of the panel to operate at high temperature. Our lightweight radiator panel offers a factor of four reduction in weight compared with present honeycomb structures and will approach 1.5 kg/m? at a fin efficiency approaching 80%. During Phase II we propose to build, test, and deliver an subscale radiator that demonstrates the advantages of the technology.","startYear":2004,"startMonth":12,"endYear":2006,"endMonth":12,"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":[],"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.
