Patent ID: 6988872

Claim:
A turbine moving blade arranged in a combustion gas flow path in which a plurality of blow-out openings for blowing out a cooling medium are formed in its outer surface, wherein among a plurality of cooling medium trailing edge blow-out openings arranged from the vicinity of a blade base to the vicinity of a blade tip along a blade trailing edge, the opening area of the blade tip trailing edge blow-out opening located in the vicinity of the blade tip is set to be larger than the opening area of all of the remaining trailing edge blow-out openings; and wherein turbulators are provided in the combustion gas flow path, in which the cooling medium turning back at the blade base trailing edge of the moving blade and flowing toward the blade tip flows, such that the inclined direction of the turbulators is upstream to downstream from a leading-edge-side wall towards a trailing-edge-side wall in the flow direction of the cooling medium.
