A method for investigating the structure in a nonisothermal turbulent boundary layer of a streamlined flat porous surface in a supersonic wind tunnel with the use of thermal radiation from a CO2-laser was developed to create a heat flux on this surface. The velocity profiles on the porous plate are measured with air blowing and non-isothermicity. The use of CO2-laser radiation in an aerophysical experiment opens up the possibility of studying the thermal protection of a surface by means of porous injection of gases and on ablating surfaces, the study of heat transfer by convection and heat radiation when injected through a porous surface of optically active gases (CO2, SF6, etc.).
