THERMAL STATE OF THE ELEMENTS OF ACTIVE AND COMBINED THERMAL PROTECTION IN GASDYNAMIC TESTS
I. K. Zharova 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.
