涡轮动叶以及燃气轮机
Abstract:
涡轮动叶(43a)具备叶片主体(51)和尖端护罩(52)。叶片主体(51)具备前缘侧冷却通路(64)、后缘侧冷却通路(67)以及中间冷却通路(65)。尖端护罩(52)具备第一排出通路(72)、第二排出通路(73)以及第三排出通路(74)。第一排出通路(72)供在前缘侧冷却通路(64)流动的冷却介质排出。第二排出通路(73)供在后缘侧冷却通路(67)流动的冷却介质排出。第三排出通路(74)供在中间冷却通路(65)流动的冷却介质排出。
Abstract(English):

A turbine blade (43a) is provided with a blade main body (51) and a tip shroud (52). The blade main body (51) is provided with a leading edge-side cooling passage (64), a trailing edge-side cooling passage (67), and a middle 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 leading edge-side cooling passage (64). The second discharge passage (73) discharges a cooling medium flowing through the trailing edge-side cooling passage (67). The third discharge passage (74) discharges a cooling medium flowing through the middle cooling passage (65).
