Abstract
L'invention a pour objet une aube de turbine, issue de fonderie, comportant une pale (14) s'étendant selon une direction d'envergure (EV) terminée par un talon (16) incluant une plateforme (17) portant au moins une léchette (18, 19) ayant un bord radialement externe destiné à coopérer avec un élément abradable (21). Selon l'invention, la léchette (18, 19) s'étend dans le prolongement de la plateforme (17) en formant un angle (A, B) par rapport à cette plateforme (17).
