This stator vane is at least provided with a blade body disposed in a combustion gas flow channel through which a combustion gas flows, a shroud that defines a part of the combustion gas flow channel, and an impingement plate attached to the shroud. A partition rib extends from a blade body end to an inner wall surface of a peripheral wall, and a shelf is provided at a rib-less part of the inner wall surface of the peripheral wall excluding at least a part in which the partition rib extends to the inner wall surface of the peripheral wall.

Stator vane and gas turbine

A turbine blade includes: a blade body; and a plurality of cooling passages each extending inside the blade body along a blade height direction and are connected to each other via return portions disposed at an end portion in the blade height direction to form a serpentine passage. The cooling passages include: an upstream passage disposed on an upstream side in a flow of a cooling fluid among the plurality of cooling passages; a downstream passage disposed on a downstream side in the flow of the cooling fluid among the plurality of cooling passages; and at least one intermediate passage disposed between the upstream passage and the downstream passage among the plurality of cooling passages. The upstream passage is disposed closest to a leading edge in a chord direction of the blade body among the plurality of cooling passages formed inside the blade body and extending along the height direction.

Turbine blade and gas turbine

A blade includes a blade body with a cooling flow passage through which a cooling medium is configured to flow. The blade body includes a top plate, and a thinning which is defined on a top surface of the top plate, closer to a suction side than a camber line, and which protrudes and extends along the camber line. A top plate flow passage is defined inside the top plate and includes an inlet flow passage which is closer to the suction side than the camber line and into which the cooling medium is configured to flow, a main flow passage which extends in a direction intersecting the camber line along the top surface, and an outlet flow passage through which the cooling medium is configured to be discharged to an outside of the blade body from a position closer to a pressure side than the camber line.
