Some features of investigations of the temperature 
dependence of the integrated and spectral emissivity of erosion-resistant 
coatings on a low-thermal conductivity fibrous heat insulation are 
discussed. Results are provided for the standard "black" and "white" 
coatings. A study is made of the influence of repeated attacks of 
the high-temperature dissociated air on the integrated emissivity 
of the "black" coating. Data are obtained on the radiation characteristics 
of this coating after full-scale tests during the Buran orbital spacecraft 
flight.
