Abstract
A cooling device for cooling the slots of a turbomachine rotor disk is provided. The turbomachine includes an upstream rotor disk having a fastener flange with a periphery that is festooned; a downstream rotor disk; an endplate for holding blades and arranged around the ring of the downstream disk and co-operating therewith to form an air diffusion cavity; a cone for driving disks in rotation and having a fastener flange with a periphery that is festooned; and a plurality of bolted connections passing from upstream to downstream through the fastener flanges of the upstream disk and of the cone, the fastener flange of the endplate, and the fastener flange of the downstream disk. The fastener flange of the endplate is pierced by ventilation orifices opening out into the air diffusion cavity, the cavity opening out into the slots of the downstream disk at their upstream ends.
