Abstract
A turbine wheel for a turbine engine is provided. The turbine wheel includes a disk carrying blades including internal channels for passing a flow of cooling air, each blade having a platform carrying an airfoil and connected by a tang to a root. The blade roots are engaged in grooves in the periphery of the disk and their tangs define between them spaces for housing sealing and damping members, which cooperate with the inside faces of the platforms to define air flow cavities. The tangs of at least some of the blades include cooling air outlet orifices that open out both into internal channels in the blades and into the cavities.
