Characteristics of Radiation Sources and Heating Devices for Thermal Testing of Materials and Structures

Radiation sources are promising for thermophysical studies, thermal and thermal strength tests of materials and structural elements subjected to high-temperature heating. Of the existing types of radiation sources, tubular radiation sources play a special role, making it possible to create test installations for heating large-sized fragments and full-scale aircraft structures by assembling them into multi-chamber heating units. For these purposes, incandescent radiation sources and high-current gas-discharge radiation sources can be used. Experimental data on the characteristics of the most common radiation sources are presented, on the basis of which heating installations have been created in relation to thermal tests of aerospace engineering structures.
