THERMAL STATE OF THE ELEMENTS OF ACTIVE AND 
COMBINED THERMAL PROTECTION IN GASDYNAMIC TESTS

UDC 524.36

A complex experimental-computational procedure of investigation 
of heat exchange on the exterior surface of a porous element of active 
thermal protection and along the surface of an element of combined 
thermal protection has been given; the procedure is based on the processing 
of results of thermogasdynamic tests by the methods of inverse heat-conduction 
problems. Results of investigation of the influence of the parameters 
of porous cooling on the efficiency of thermal protection of the heated 
surface have been presented. Results of investigation of the intensity 
of heat exchange on the surface of a glass-reinforced-plastic plate 
in the curtain zone for different parameters of injection have been 
given, and conclusions on the efficiency of porous cooling as a function 
of the intensity of injection of a coolant have been drawn.
