    摘要: The internal cooling of the moving blades of the turbines in aircraft turbomachines is limited in effectiveness because of inhomogeneities of this cooling on each of the pressure-face and suction-face walls. To address this problem, there is proposed a blade comprising a circuit (50) for cooling the airfoil part (34) thereof, in which circuit the cavities interconnected in series are such that the stream of air flows radially toward the outside along the pressure-face wall (40) in pressure-face cavities (52, 56), and radially toward the inside along the suction-face wall (42) in a suction-face cavity (54) that is separated from the pressure-face cavities by an internal wall (58) of the airfoil part. In this way, the force of the Coriolis effect deflects the stream of air toward each of the pressure-face and suction-face walls thereby limiting the inhomogeneity.

    摘要: The invention concerns a turbine blade (11) for a turbomachine, comprising a vane (12) extending in a spanwise direction between a root and a tip, a first inner side cavity (54) running along the pressure-side wall (21) and a second inner side cavity (56) running along the suction-side wall. The blade (11) further comprises at least one inner central duct (53) configured to collect air intended to cool the vane (12). The central duct (53) extends between the side cavities (54, 56), being separated from the side cavities (54, 56) so as to be at least partially thermally isolated from the pressure-side wall (21) and the suction-side wall. The side cavities (54, 56) communicate with each other in a junction region (72) located downstream from the central duct (53), over the majority of the height of the central duct in the spanwise direction.
