Abstract
L'invention concerne une aube de turbine de turbomachine telle qu'un turboréacteur, cette aube comprenant un pied portant une pale (22a) qui s'étend selon une direction d'envergure (EV) en se terminant par un sommet (S), cette pale (22a) comprenant une paroi d'intrados (23a) et une paroi d'extrados (24a) se terminant chacune par un bord terminal (27a, 28a) au niveau du sommet (S) de pale (22a), la pale (22a) comportant à son sommet (S) une paroi de fermeture (26a) s'étendant de l'intrados (23a) à l'extrados (24a) pour délimiter avec ces bords terminaux une forme en baignoire (29). Selon l'invention, la paroi d'intrados (23a) est incurvée de manière à s'écarter de la direction d'envergure (EV) dans la région du sommet (S) de pale qui précède la baignoire (29), entre le pied et le bord terminal de l'intrados.
