Abstract

Cette invention concerne une aube mobile (20) avec passages de refroidissement (22, 23) séparés par une nervure (51). L'air de refroidissement (41) traverse le passage de refroidissement (22), puis pénètre dans le passage de refroidissement (23) comme indiqué par la flèche (41e). Dans le coin situé à l'avant du passage de refroidissement (22) se trouve une zone stagnante sans trou de refroidissement (50). Toutefois, un flux (41i) sort de l'aube par un trou de refroidissement (2) et va se former dans cette zone. Par ailleurs, à l'extrémité avant d'une nervure (51) se forme une région de pelage? ¿(52) due au pelage du débit, mais l'air de refroidissement (41h) quitte l'aube par un trou de refroidissement (1). Il y a donc un flux d'air de refroidissement dans cette zone. L'invention porte également sur une configuration à trous de refroidissement pour pellicule. Une aube mobile de turbine à gaz comporte des agitateurs pluri-étagés (28) sur la surface de la paroi intérieure de passages de refroidissement (60), ce qui a pour effet d'éliminer le pelage de l'air de refroidissement entre les agitateurs (28).
