PURPOSE: To form cooling air channels through which moving blade parts and platforms can be sufficiently cooled. CONSTITUTION: Holes 2A, 2B, 2C through which cooling air is led to flow into serpentine channels for cooling a blade part, are opened in a gas turbine cooled moving blade. The terminals of the serpentine channels serve as platform 3 parts, and reservoirs 4 are formed thereon. Holes 6 for cooling convection, which are communicated with the reservoirs 4, are opened in the platforms 3 so as to cool the platforms 3. Further, holes through which the cooling air is led to flow from the holes 6 for cooling the convection onto the upper surfaces of the platforms 3, are also opened. |
