Beschreibung
Zusammenfassung:	The invention relates to a turbine rotor for a turbomachine, comprising a disk (21) containing slots for mounting vane roots, each slot being defined by two adjacent teeth (5) of the disk (21), the vane roots comprising contact surfaces bearing on contact surfaces of the teeth (5) of the disk (21). Foils (24) are mounted on the teeth (5) of the disk (21), each foil (24) having a general U-shape comprising lateral bearing parts inserted between the corresponding contact surfaces of the vane roots and teeth (5) of the disk (21), and a central part (26) facing the peak of the corresponding tooth (5) of the disk (21) and defining a cavity (27) between said peak and the foil (24). The turbine rotor also comprises means (28) for supplying cooling air into said cavity (27).
