Abstract
L’invention concerne une aube de turbine d'une turbomachine telle qu'un turboréacteur, destinée à être montée sur un disque de rotor tournant autour d’un axe longitudinal (AX), comprenant une pale (12) s’étendant selon une direction d'envergure (EV), la pale (12) comprenant une paroi d'intrados (19) et une paroi d'extrados (21), ainsi qu’un bord de fuite (17) comprenant un bord aval d’extrados (24) et un bord aval d’intrados (26), le bord aval d’intrados (26) étant situé en amont du bord aval d’extrados (24). Le bord aval d’intrados (26) est situé à distance de la paroi d’extrados (21) selon une direction transverse, et il est relié à la paroi d’extrados (21) par des nervures (27) orientées longitudinalement et régulièrement espacées selon la direction d’envergure (EV). L’aube comprend au moins un perturbateur (29) d’écoulement situé entre deux nervures consécutives. Figure pour abrégé : Figure 2
