Abstract

L’invention concerne une aube de turbine, comprenant un pied prolongé par une pale se terminée par un sommet, la pale comprenant une paroi d'intrados et une paroi d'extrados, ainsi qu’un bord d'attaque (16), un bord de fuite (17) et une paroi de fermeture (22) les reliant, la paroi de fermeture (22) comportant une face radialement externe (31) et une face radialement interne (32) et étant traversée par un trou de dépoussiérage (28). Le trou de dépoussiérage (28) comporte une portion d’évacuation (E) rectiligne de section constante débouchant dans la face externe (31) en étant raccordée à cette face externe (31) par une arête, cette portion d’évacuation (E) étant prolongée par une portion d’admission (A) dont au moins une partie est raccordée à la face interne (32) par une surface de liaison (33) formant un raccordement courbe avec la face interne (32). Figure pour l’abrégé : Figure 6
