Abstract (en)
[origin: EP1621735A2] The gas turbine rotor has blades (4) with inner space cooled and a mechanical sealing and damping component between the opposing side surfaces (6) of the adjacent blade platforms (7). The gap between the side surfaces is additionally dynamically sealed in relation to the hot gas flow. Cooling air is conducted via a cooling channel (9) out of a hollow space (5) of the rotor blades into the gap between the side surfaces.
