Abstract

Des rainures (46) ménagées coopèrent avec les talons d'aubes (40), afin de définir deux passages d'air de refroidissement (55, 208) en travers de chaque rainure. Ce passages (55, 208) sont dans une relation mutuelle d'écoulement en série. L'air de refroidissement provenant d'un endroit situé en amont du rotor (34) est acheminé dans un passage (55) de chaque rainure (46), pour y refluer ensuite en travers de celle-ci. La meme masse d'air est alors dirigée dans l'entrée de l'autre passage (208) pour refroidir davantage les talons (40) et les pattes (47).
