RT Journal Article ID 3381c0cd257a6174 A1 Paderin, Leonid Yakovlevich A1 Prusov, Boris Viktorovich A1 Tokarev, Oleg Dmitrievich T1 FACILITY FOR INVESTIGATIONS OF TOTAL HEMISPHERICAL EMISSIVITY OF HEAT PROTECTION MATERIALS AND THERMAL CONTROL COATINGS JF TsAGI Science Journal JO TSAGI YR 2011 FD 2011-09-08 VO 42 IS 1 SP 71 OP 82 K1 heat protection materials K1 thermal control coatings K1 total hemispherical emissivity K1 temperature K1 total radiant flux AB This work is dedicated to an improvement of technique and modernization of experimental facility for the purpose of the maximum temperature level increase at investigations of total hemispherical emissivity of heat protection materials and thermal control coatings. Within the scope of the facility modernization a new heater based on modern high temperature materials and new measurement instruments for temperature and radiant heat flux measurements are developed. As a result of the conducted measures the maximum temperature level of samples under study is increased from 1500 up to 2000 K. A series of control tests are carried out. These tests verify the technique efficiency and operability of the modernized experimental facility in an extended temperature range.
