Thermophysics and Thermal Power Engineering| Резюме: | Considered and analyzed schemes of internal cooling of gas turbine blades starting from their initial application to the present time. Systematized methods of cooling the leading edge, the middle part and the trailing edge. The methods of heat transfer augmentation, which are used in blade cooling systems, are analyzed. An analysis of perspective methods of internal cooling was performed. Among them, we can single out cyclone cooling and the use of dimples on the surfaces of the channels. These technologies provide the high thermo-hydraulic performance of cooling channels. It is shown that the main trend of the development of cooling systems is the use of microchannel schemes, with the maximum approach of the cooling channels to the outer surface of the blade. These methods become possible due to the development of new casting technologies and additive technologies. |
