ABSTRACT:
A hexagonal protective and high temperature resistant system for the Space Shuttle Orbiter consists of a multiplicity of pockets formed by hexagonally oriented spacer bars 11 secured ot the vehicle substructure 12, a packing of low density insulating batt material 18 in each pocket, and a thin protective panel 19 of laterally resilient advanced carbon-carbon material surmounting the peripheral bars 11 and packing 18. Each panel 19 has three stepped or offset lips on contiguous edges, as M-1, M-2, M-3, the other three edges, as M-4, M-5, M-6, being non-stepped, i.e., flat so that complementary edges of abutting panels rest against the peripheral bars. At the center of each pocket is a fully insulated stanchion 15 secured to and connecting the substructure and panel for flexing the panel toward the substructure and thereby prestressing the panel and forcing the panel edges firmly against the spacer bars.
