摘要： Holes 38 and 39 have upstream opening portions 38b and 39b and downstre am opening portions 38a and 39a which have a larger cross-sectional area than upstream opening portions 38b and 39b, and are formed at top portion TP of each movin g blade. Holes 38 and 39 have tapered shapes T1 and T2 or step portions, and preferably, downstream opening portions 38a and 39a are eccentrically formed toward the moving direction. When tip squealer 37 is formed, hole 38 is formed so that its opening portion is provided at the side surface of tip squealer 37. Without covering the holes for cooling which are formed at the top portion of the turbine blade due to rubbing or the like, the turbine bla de is accurately cooled and stably driven.

摘要： A stationary blade (133) of a gas turbine (10), which. can reduce thermal stress produced at a portion in the vicinity of a rear edge of an inner shroud (133 c) of the stationary blade. The stationary blade is positioned adjacent to at least on e oil moving-blade disks (32e, 34e, 36e, 38e) in an axial direction of the gas turbine. A concave portion (40) is provided in the inner shroud in a manner such that t he concave portion is formed in the vicinity of a rear edge of the inner shroud and on an inner-peripheral face of the inner shroud, where cooling air passes along th e inner-peripheral face which faces a rotation shaft of the moving-blade disks ; and a protruding portion (133i) which protrudes towards the rotation shaft is form ed at the rear edge of the inner shroud.

摘要： A stationary blade (133) of a gas turbine (10), which can reduce thermal stress produced at a portion in the vicinity of a rear edge of an inner shroud (133c) of the stationary blade. The stationary blade is positioned adjacent to at least one of moving-blade disks (32e, 34e, 36e, 38e) in an axial direction of the gas turbine. A concave portion (40) is provided in the inner shroud in a manner such that the concave portion is formed in the vicinity of a rear edge of the inner shroud and on an inner-peripheral face of the inner shroud, where cooling air passes along the inner-peripheral face which faces a rotation shaft of the moving-blade disks; and a protruding portion (133i) which protrudes towards the rotation shaft is formed at the rear edge of the inner shroud.

摘要： A collision plate having plural small holes is provided at an interval from a bottom surface of an inner shroud to form a chamber and guides cooking air from the small holes into the chamber. A leading edge flow path is provided at a leading edge sid e along a width direction and introduces the cooling air. A side flow path is provided along both sides of the inner shroud and guides the cooling air to a trailing edge side. A heade r is formed along the width direction near the trailing edge and guides the cooling air from the side flow path. Plural trailing edge flow paths are formed at the trailing edge side a t intervals along a width direction, in which one end of each flow path is connected to the head er and the other end is open at the trailing edge, and the cooling air in the header is eject ed from the trailing edge.
