ABSTRACT:
A system for providing thermal insulation for portions of a spacecraft which do not exceed 900.degree. F. (756.degree. 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.
