Abstract (en)
[origin: WO2011080319A1] The invention relates to a blade, for example a high-pressure turbine blade, which is designed to have an inner partition (9) closest to the trailing edge (7), the upper portion (20) of which is slanted towards said edge, so as to promote the ventilation of cooling gases towards the openings (15) of said edge, and more generally the ventilation of the upper corner of the blade, by creating new openings (14') at the top (11) or by the movement of original openings (12) of the second cavity, and leading to the lower surface in the direction of the trailing edge.
