Abstract
A blade cooling structure of a gas turbine, which can reduce the pressure loss of a cooling medium without decreasing the heat transfer coefficient, is provided. The blade cooling structure comprises a cooling passage () for flowing cooling air (A) from a proximal end portion () toward a blade portion () of a moving blade (), a plurality of turbulators () arranged, on both wall surfaces of the cooling passage () opposing each other, in such a manner as to be inclined with respect to the flowing direction of the cooling air (A), and a plurality of dimples () formed in a downstream region (N) downstream of a center position (O) in the flowing direction of the cooling air (A) on the wall surface of the cooling passage () between the adjacent turbulators ().
