THERMAL INSULATIONS FOR AEROSPACE APPLICATIONS: -423 TO 3000 F

Abstract

Very recent advances in thermal insulation developments for the temperature range from liquid hydrogen (-423 F) to +3000 F are reviewed. Some fundamental discussion of convective, conductive, and radiative heat transport mechanisms over this wide temperature range is included in analyzing the observed thermal characteristics of various insulation materials and composites. Variations in overall thermal conductance as a function of such parameters as absolute temperature level, interstitial gas pressure, density, radiation scattering and attenuation, and insulation geometry are discussed for recently developed powders, fibers, foams, and multilayer composites. Recent experimental results of USAF programs on these types of materials are presented and analyzed.
