Abstract (en)

[origin: EP2025867A1] The rotor (12) has multiple rotor discs (10,14,16,24,26) that are arranged in stacks and clamped together with a tie rod (58). The rotor discs (24,26) of the rotor comprises a smaller outer diameter than one of the neighboring rotor discs (16) and that the difference in diameter is compensated by a drum (28) surrounding the rotor disc with the smaller outer diameter as a ring. An independent claim is included for a gas turbine with a compressor.
