Abstract

La présente invention concerne un ensemble de turbine (10) pour une turbomachine (1) s’étendant autour d’un axe, comprenant un ensemble de rotor, un ensemble de stator, et des moyens d’étanchéité, les moyens d’étanchéité séparant une première cavité (C1) d’une deuxième cavité (C2). L’ensemble de turbine (10) comprend au moins deux éléments (121, 122) de rotor assemblés par au moins un boulon (50) de fixation, ledit au moins un boulon (50) de fixation comprenant une vis (51) et un écrou (52), l’écrou (52) étant situé dans la première cavité (C1) et présentant un dispositif d’accélération d’un flux d’air au sein de la première cavité (C1), le dispositif d’accélération du flux d’air comprenant au moins une ailette (55) en saillie de l’écrou (52), l’ailette (55) s’étendant selon une direction radiale partant d’un axe de révolution (I) de l’écrou (52).
