Abstract : The purpose of this paper is to discuss thermal protection systems and the Thermantic Structure developed by Aeronca Manufacturing Corporation, to withstand temperatures in excess of 3000 F for extended periods of time (approximately one hour) and to resist severe noise and dynamic loads associated with space vehicle flight. The heat shield, made of a low density ceramic foam reinforced with a honeycomb cell structure, is capable of maintaining an internal temperature suitable for the survival of both man and sensitive equipment. The thermantic structure uses a conventional load bearing panel fabricated from alloy sheets brazed to stainless steel honeycomb and this panel brazed to the ceramic honeycomb reinforcement. This ''Astroshield'' concept offers the combined advantages of high temperature resistance, lightweight, thermal shock resistance, chemical stability and high strength. (Author)
