Abstract

In article the method of experimental definition catalytical and radiating properties of perspective materials of heat shield oj space flying apparatus (SFA) of the planning class is stated. The method is developed with the purpose of use on high-temperature gasdynamics stands reproducing natural thermal parameters at flight of SFA in an atmosphere of the Earth and other planets. The analysis of influence catalytical and radiating properties on heat exchange on surface SFA is carried out. Algorithms of experimental definition of these properties are offered. Importance of the results stated in work is supported with that fact, that catalytical and radiating properties appear the unique factor, capable to reduce a supply of heat to a surface of a space vehicle at flight in dense layers of an atmosphere with hypersonic speed.
