ABSTRACT:
On a gas turbine rotor with internally cooled airfoils (4) of the turbine rotor blades and a mechanical sealing and damping element arranged between opposite side faces (6) of adjacent blade platforms (7), the gap is additionally aerodynamically sealed against the hot gas flow, by cooling air supplied from a cavity (5) of the airfoils via a cooling duct (9) into the gap between the side faces (6).
