Abstract:
A plurality of circumferential blowout passages that communicate with a cavity into which cooling air flows and that open in a circumferential end surface are formed in a shroud of a vane. Of a central region of the circumferential end surface, an upstream-side region of the circumferential end surface, and a downstream-side region of the circumferential end surface, at least the central region has openings of the plurality of circumferential blowout passages formed therein. A density that is the number of the openings of the circumferential blowout passages per unit length in an axial direction is highest in the central region.

Claim (Index 1):
A vane of a gas turbine in which a plurality of vanes are disposed in an array in a circumferential direction around a rotor shaft, the vane comprising:\n a vane body that is disposed inside a combustion gas flow passage through which combustion gas flows, and that extends in a radial direction of the rotor shaft; and a shroud that is formed at an end of the vane body in the radial direction and defines a part of the combustion gas flow passage, wherein the shroud has a gas path surface that faces the radial direction and comes in contact with the combustion gas, a pair of circumferential end surfaces that face opposite sides in the circumferential direction, a cavity into which cooling air flows, and a plurality of circumferential blowout passages that communicate with the cavity and open in the circumferential end surface, the circumferential end surface has a central region that is a region located inside a throat circle being a circle with a minimum radius of circles in contact with both the vane body of the vane and a vane body of another vane adjacent to the vane in the circumferential direction, an upstream-side region that is located further on an upstream side of the combustion gas flow passage than the central region, and a downstream-side region that is located on the opposite side of the central region from the upstream side, and openings of the plurality of circumferential blowout passages are formed at least in the central region, and a density that is the number of the openings of the circumferential blowout passages per unit length in an axial direction in which the rotor shaft extends is higher in the central region than in the upstream-side region and the downstream-side region.
