Abstract
An axial turbomachine rotor is provided. The rotor includes a rotor disk and a rotor blade ring, which includes a plurality of rotor blades, each of which include a blade root, with which the rotor blade is fixed radially outward on the rotor disk, wherein the blade root is engaged with the rotor disk at the outer edge of the rotor disk in a form-closed manner in such a way that during operation of the rotor, a gap is formed between the rotor blade and the rotor disk at a predetermined surface area of the rotor disk, in which area, a plurality of impingement cooling openings is arranged, through which a cooling medium may flow from the interior of the rotor disk into the gap whereby the rotor blade is cooled using the cooling medium by means of impingement cooling.

An axial turbomachine having a rotor disk and a rotor blade ring, comprising:
- a plurality of rotor blades, each including a blade root by which the rotor blade is fixed radially outwards on the rotor disk;
- and
- a plurality of impingement-cooling openings,
- wherein the blade root engages with the rotor disk on an outer edge of the rotor disk in a form-fitting manner in such a way that during operation of the axial turbomachine rotor, a gap is formed between the rotor blade and the rotor disk in a predetermined surface region of the rotor disk, and
- wherein in the gap are arranged the plurality of impingement-cooling openings through which a cooling medium may flow from an interior of the rotor disk into the gap, as a result of which the rotor blade is cooled by the cooling medium by means of impingement cooling and the rotor disk is cooled by the cooling medium by means of convective cooling.
