Abstract

L'invention concerne une aube (13) de turbine pour une turbomachine comportant une pale (14) s'étendant radialement, la pale (14) comprenant un bord d'attaque (16) axialement amont et un bord de fuite axialement aval, une plate-forme (15) radialement externe comprenant une extrémité amont (17) et une extrémité aval, la plate-forme (15) radialement externe comprenant au moins une léchette (18, 19) s'étendant radialement vers l'extérieur, l'extrémité radialement externe (20) du bord d'attaque (16) de la pale (14) et/ou du bord de fuite de la pale (14) s'étendant axialement vers l'amont par rapport à l'extrémité amont (17) de la plate-forme (15) et/ou respectivement vers l'aval par rapport à l'extrémité aval de la plate-forme (15), caractérisée en ce que l'aube (13) comporte au moins une cloison (21) s'étendant radialement vers l'extérieur depuis l'extrémité radialement externe de la pale (14), et axialement entre le bord d'attaque (16) et l'extrémité amont (17) de la plate-forme (15), et/ou respectivement entre le bord de fuite et l'extrémité aval de la plate-forme (15).
