Abstract
A moving blade for a turbomachine, the central portion of the blade including a pressure-side cooling circuit and a suction-side cooling circuit. The pressure-side circuit comprises at least first and second pressure-side cavities extending from the pressure side of the blade to a central wall, a central cavity extending from the pressure side to the suction side of the blade, and outlet orifices opening out from the central cavity and into the pressure-side face of the blade. The suction-side circuit comprises at least first and second suction-side cavities extending radially from the suction side of the blade to the central wall, a central cavity extending across the blade from the pressure side to the suction side, and outlet orifices opening out from the central cavity and into the pressure-side face of the blade.
