Title (EN) TURBINE ROTOR BLADE, AND GAS TURBINE
(FR) PALE DE ROTOR DE TURBINE, ET TURBINE À GAZ
(JA) タービン動翼、及び、ガスタービン
Abstract:
(EN) This turbine rotor blade (43a) is provided with a blade main body (51) and a tip shroud (52). The blade main body (51) is provided with a front edge-side cooling passage (64), a rear edge-side cooling passage (67), and an intermediate cooling passage (65). The tip shroud (52) is provided with a first discharge passage (72), a second discharge passage (73), and a third discharge passage (74). The first discharge passage (72) discharges a cooling medium flowing through the front edge-side cooling passage (64). The second discharge passage (73) discharges a cooling medium flowing through the rear edge-side cooling passage (67). The third discharge passage (74) discharges a cooling medium flowing thorough the intermediate cooling passage (65).
(FR) L'invention concerne une pale de rotor de turbine (43a), laquelle pale comporte un corps principal de pale (51) et un carénage de pointe (52). Le corps principal de pale (51) comporte un passage de refroidissement côté bord avant (64), un passage de refroidissement côté bord arrière (67), et un passage de refroidissement intermédiaire (65). Le carénage de pointe (52) comporte un premier passage d'évacuation (72), un deuxième passage d'évacuation (73), et un troisième passage d'évacuation (74). Le premier passage d'évacuation (72) évacue un milieu de refroidissement s'écoulant à travers le passage de refroidissement côté bord avant (64). Le deuxième passage d'évacuation (73) évacue un milieu de refroidissement s'écoulant à travers le passage de refroidissement côté bord arrière (67). Le troisième passage d'évacuation (74) évacue un milieu de refroidissement s'écoulant à travers le passage de refroidissement intermédiaire (65).
(JA) タービン動翼(43a)は、翼本体(51)と、チップシュラウド(52)と、を備える。翼本体(51)は、前縁側冷却通路(64)と、後縁側冷却通路(67)と、中間冷却通路(65)と、を備える。チップシュラウド(52)は、第一排出通路(72)と、第二排出通路(73)と、第三排出通路(74)と、を備える。第一排出通路(72)は、前縁側冷却通路(64)を流れる冷却媒体を排出する。第二排出通路(73)は、後縁側冷却通路(67)を流れる冷却媒体を排出する。第三排出通路(74)は、中間冷却通路(65)を流れる冷却媒体を排出する。
