Abstract (en)
[origin: EP2146051A1] A rotor assembly (2) for a gas turbine (1) is provided with a rotor ring (3) extending about a longitudinal axis; a plurality of rotor blades (4) radially arranged about the rotor ring (3) and having an end portion (7) fixed to the rotor ring (3); and a plurality of sealing elements (30) arranged side-by-side in a circumferential direction, each of which is adapted to be coupled to the rotor ring (3) and to at least one blade (4) and is provided with an external face (32) adapted to be arranged in contact with a hot working fluid in the gas turbine (1) and with an internal face (33) adapted to be arranged in contact with a cooling fluid of the gas turbine (1); the blades (4) and the sealing elements (30) are shaped so as to form, when reciprocally coupled, at least one annular cooling channel (37) adapted to be traveled through by the cooling fluid.
