<p>The rotor has a rotor blade ring including rotor blades with a blade root radially fixed outward on a rotor disk (2). The blade root is engaged at an outer edge (13) of the rotor disk in a form-closed manner such that a gap is formed between the rotor blades and the disk at a predetermined surface area of the rotor disk during operation of the rotor. A cooling medium flows through impingement cooling openings (12, 15) from an interior surface of the rotor disk into the gap, where the rotor blades are cooled by the impingement cooling openings using the cooling medium.</p> |
