Abstract:
(EN) A blade main body (51) of this gas turbine is provided with: a first cooling passage part (58); a second cooling passage part (59); a column part (60); and a plurality of protrusions. The first cooling passage part (58) is provided at the side near to the front edge (55). The second cooling passage part (59) is provided at the side near to the rear edge (56). The column part (60) is provided between the first cooling passage part (58) and the second cooling passage part (59), and is continuously formed between an end part and a base part of the blade main body (51). The plurality of protrusions protrude from the inner wall surfaces of the first cooling passage part (58) and the second cooling passage part (59).
(FR) Selon l'invention, un corps principal de pale (51) d'une turbine à gaz comprend : une première partie passage de refroidissement (58) ; une deuxième partie passage de refroidissement (59) ; une partie colonne (60) ; et une pluralité de saillies. La première partie passage de refroidissement (58) est située sur le côté à proximité du bord avant (55). La deuxième partie passage de refroidissement (59) est située sur le côté à proximité du bord arrière (56). La partie colonne (60) est située entre la première partie passage de refroidissement (58) et la deuxième partie passage de refroidissement (59), et est formée de manière continue entre une partie d'extrémité et une partie base du corps principal de pale (51). La pluralité de saillies dépasse des surfaces de paroi intérieure de la première partie passage de refroidissement (58) et de la deuxième partie passage de refroidissement (59).
(JA) ガスタービンの翼本体(51)は、第一冷却通路部(58)と、第二冷却通路部(59)と、柱部(60)と、複数の突出部とを備える。第一冷却通路部(58)は、前縁(55)に近い側に設けられる。第二冷却通路部(59)は、前記後縁(56)に近い側に設けられる。柱部(60)は、前記第一冷却通路部(58)と前記第二冷却通路部(59)との間に設けられて、前記翼本体(51)の基部と端部との間に連続して形成される。複数の突出部は、前記第一冷却通路部(58)の内壁面と、前記第二冷却通路部(59)の内壁面とから突出する。
