Beschreibung
Zusammenfassung:	A turbine rotor for a turbomachine, including a disk containing slots for mounting vane roots, each slot being defined by two adjacent teeth of the disk, the vane roots including contact surfaces bearing on contact surfaces of the teeth of the disk. Foils are mounted on the teeth of the disk, each foil having a general U-shape including lateral bearing parts inserted between the corresponding contact surfaces of the vane roots and teeth of the disk, and a central part facing the peak of the corresponding tooth of the disk and defining a cavity between said peak and the foil. The turbine rotor also includes a device for supplying cooling air into said cavity.
