Abstract (en)
The blade has intrados cooling circuit comprising intrados cavities (24, 26) extending from an intrados lateral side (20) to a central wall (30), a central cavity (28) extending from the side (20) to an extrados lateral side (22), and outlet orifices (40) opened in the cavity (28) and leading on the side (20). An extrados cooling circuit comprises extrados cavities (42, 44) radially extending from the side (22) to the central wall, a central cavity (46) extending from the side (20) to the side (22), and outlet orifices (54) opened in the cavity (46) and leading on the side (20).
