Abstract

The results of calculations and analysis of the effect of perforation of the turbine blade wall and air film from the holes, as well as heat-shielding coatings on the temperature and stress state of the turbine blade of the loop cooling circuit are presented. The results of calculations of the temperature along the height of the blade by 2D and 3D models are compared.
