Patent ID: 7661930

Claim:
A moving blade for a turbomachine, the central portion of the blade being geometrically subdivided into four adjacent pressure-side zones disposed on the pressure side of the blade, and into four adjacent suction-side zones disposed on the suction side, the pressure-side and suction-side zones being distributed on opposite sides of the skeleton of the blade, the blade including in its central portion both a pressure-side cooling circuit and a suction-side cooling circuit that are independent from each other, the pressure-side cooling circuit comprising three radial cavities occupying three adjacent pressure-side zones, and the suction-side cooling circuit comprising three radial cavities occupying the four suctionside zones and the remaining pressure-side zone, wherein the blade further includes a trailing edge cooling circuit that is independent from the pressure-side and suction-side cooling circuits and that comprises at least one radial cavity in the vicinity of the trailing edge of the blade, at least one air admission orifice opening into the cavity of the trailing edge cooling circuit, and outlet orifices opening out into the trailing edge of the blade.
