Abstract
The invention provides a gas turbine blade that is capable of reducing the temperature difference between the pressure side and the suction side even if the trailing-edge cooling channel is narrow, thereby lessening thermal stress as well. A gas turbine bladecomprises: an internal trailing-edge cooling channel formed by a suction-side cooling target surfaceand a pressure-side cooling target surfacethat face each other; and multiple vortex-generator-shaped finsdisposed between the two cooling target surfacesandsuch that the finsconnect the two cooling target surfacesand. Each of the vortex-generator-shaped finsincludes an oblique surfacelocated on the downstream side of the flow direction of a cooling medium. A normal lineto the oblique surfaceintersects with one of the two cooling target surfacesand
