Abstract
L’invention concerne un aubage de turbomachine s’étendant autour d’un axe et comportant une pale (14) s’étendant radialement par rapport à l’axe, ladite pale (14) comportant une surface d’intrados (17) et une surface d’extrados reliées l’une à l’autre au niveau d’un bord d’attaque (19) amont et d’un bord de fuite (20) aval, au moins une plate-forme radialement interne (15) et/ou radialement externe, à partir de laquelle s’étend la pale (14), ladite plate-forme (15) comportant une surface de veine (24), tournée vers la pale (14) et destinée à délimiter une partie d’une veine d’écoulement des gaz au sein de la turbomachine, la plate-forme (15) comportant une partie amont (25), située en amont de la surface de veine (24) et s’étendant radialement à l’opposé de la pale (14), par rapport à la surface de veine (24), caractérisé en ce que la plate-forme (15) comporte un bossage (26) radialement en saillie en direction de la pale (14), ledit bossage (26) étant situé en amont du bord d’attaque (19) de la pale (14), ledit bossage (26) s’étendant dans la partie amont (25) de la plate-forme (15).
