Abstract

Aube de rotor (10) d'une turbine à gaz, en particulier de turboréacteur, comprenant une pale, une plateforme (20) raccordant la pale à un pied d'aube (22) et comportant au moins un raidisseur (26) s'étendant sous la partie aval de la plateforme (20), et des moyens de refroidissement de l'aube (10) par circulation d'un fluide de refroidissement dans des conduits (34) formés dans la pale, et dans une cavité (50) formée dans le raidisseur (26) sensiblement au droit du bord de fuite (18) de la pale et comportant des orifices de sortie (58) orientés vers l'aval.

Figure imgaf001
A rotor blade (10) of a gas turbine, in particular a turbojet, comprising a blade, a platform (20) connecting the blade to a blade root (22) and comprising at least one stiffener (26) extending under the downstream portion of the platform (20), and blade cooling means (10) by circulating a cooling fluid in ducts (34) formed in the blade, and in a cavity (50) formed in the stiffener (26) substantially to the right of the trailing edge (18) of the blade and having outlets (58) facing downstream.
