CERAMIC SYSTEMS FOR MISSILE STRUCTURAL APPLICATIONS
Abstract
Five slip-cast fused silica radomes were fabricated and evaluated in a Mach 2.2, 4000 F, 140 psia Typhon ramjet exhaust at General Dynamics/Pomona Ordnance Aerophysics Laboratory July 6-18, 1966. Test data is to be presented in a separate report prepared and published by the Johns Hopkins University, Applied Physics Laboratory, Silver Spring, Maryland. Preliminary observations are presented and it is estimated that 50 to 60 per cent of the test objectives were realized. Materials development and characterization studies of slip-cast alumina-fused silica composites and fused silica grinding for strength improvement are presented. Studies for applying metal films on slip-cast fused silica substrates for antenna applications were completed. Fabrication of felts from refractory fibers of fused silica, boron nitride, zirconia, magnesia, and silicon carbide coated graphite fibers and impregnation of a phenolic embedded ablator in these felts and comparison of thermal evaluation results of these embedded felts with standard ablators under a heat flux of 450 and 1500 BTU/sq ft-sec are described.
