A system for providing thermal insulation for portions of a spacecraft which do not exceed 900°F. (756°K.) during ascent or reentry relative to the earth\s atmosphere. The thermal insulation is formed of relatively large flexible sheets of needled Nomex felt having a flexible waterproof coating. The thickness of the felt is sized to protect against projected temperatures and is attached to the structure by a resin adhesive. Vent holes in the sheets allow ventilation while maintaining waterproofing. The system is heat treated to provide thermal stability.
Reuseable thermal insulation attached to portions of a space vehicle where surface temperatures will not exceed 900°F. (765°K.) while passing through the atmosphere, comprising: a sheet of felt of thermally stable, flexible, insulation material, said felt comprised of needled, high temperature resistant, flexible plastic filaments of poly (1,3-phenylene isophthalamide), said sheet being preheat-treated to avoid subsequent adverse shrinkage; said felt having a thickness commensurate with the projected thermal environment of the area of the space vehicle b...
