We have investigated the serviceability of the heat-insulating 
tiles of the orbital aircraft "Buran" under radiant heating on an 
SGU-7 solar plant with a mirror concentrator 5 m in diameter. Cycles 
of aerodynamic heating with a duration of 20 min were simulated. For 
the total number of cycles for different materials from 20 to 85, 
the efficiency and serviceability of TZMK-type materials with different 
coats have been corroborated. The results obtained agree with the 
test data obtained on gas-dynamic (power consumption 1 MW) and radiation 
(250 kW) test beds, which enables such tests to be recommended for 
use at preliminary stages in power-saving and ecologically harmless 
solar furnaces.
