Abstract
La présente invention concerne une aube de turbine refroidie pour moteur à turbine à gaz, comprenant une paroi intrados (13), une paroi extrados (14) et une paroi distale (15) reliant les parois intrados et extrados, agencées de manière à ménager, au niveau de l'extrémité distale (12) de l'aube, au moins une cavité externe (16) formant baignoire et au moins une cavité externe (17) séparées par la paroi distale (15), l'aube présentant au moins une ouverture (18) pour l'introduction d'un flux d'air de refroidissement (FR) dans la cavité externe (16), caractérisée en ce que, d'une part, au moins une partie (15) de la paroi distale (15) est inclinée par rapport aux normales à la paroi intrados (13) et, d'autre part, l'ouverture (18) est ménagée au voisinage de la paroi distale (15) de manière que le flux d'air de refroidissement (FR) soit dirigé vers l'extrémité distale (13A) de la paroi intrados (13)..
