Innovative Materials Solutions will demonstrate a thermal protection system concept which facilitates rapid replacement of insulating tiles and ready access to the substructure. Our concept is based on lab-proven materials technologies. The Phase I program will involve establishing design requirements, selecting materials, and producing and testing relevant joint specimens. The follow-on Phase II program will demonstrate fabrication and testing of scaled reentry vehicle leading edge TPS. We have teamed with a major military aerospace reentry vehicle systems integrator. This will ensure development of a technology that is relevant for Air Force systems
