INVESTIGATION OF FEASIBILITY OF UTILIZING AVAILABLE HEAT RESISTANT MATERIALS FOR HYPERSONIC LEADING EDGE APPLICATIONS. VOLUME IV. THERMAL PROPERTIES OF MOLYBDENUM ALLOY AND GRAPHITE

The feasibility of utilizing heat-resistant materials in the fabrication of leading edges for hypersonic boost-glide vehicles was investigated. The results of measurements of the thermal conductivity, specific heat, linear thermal expansion, and emittance of a 0.5% titanium alloy of molybdenum, and of siliconized ATJ graphite as a function of temperature are presented. Emittance measurements were made on coated and uncoated materials. (auth)
