Inconel-covered Cerachrome Insulation Missions: Unknown   Comment: Inconel 718 and A-286 fittings are bolted to the flanges on the RCC components This segment of Inconel-covered cerachrome insulation once was bolted to a flange on a reinforced carbon-carbon (RCC) component of the shuttle's leading edge structure and was attached to an aluminum wing spar. It protected the metallic fittings and spar from the heat radiated during reentry from the inside surface of the RCC wing panels. After at least one Space Shuttle mission, this piece was marked Unserviceable (Condemned) and was disposed of as scrap by NASA. back to Artifacts © 1999-2008 collectSPACE.com All rights reserved.
