Abstract

The results of numerical and experimental investigations into the efficiency of convective cooling of a high-temperature gas turbine cooling blade manufactured using the serial technology methods are presented. The influence of the actual geometry of the rib within the internal cooling duct at the blade leading edge on the thermal state of the blade during full-scale operation was determined.
