Abstract (en)

It is described an arrangement (60) for damping vibrations in a gas turbine (10), comprising: a rotor shaft (22) arranged for rotating; a first rotor component (62) connected to the rotor shaft (22); a second rotor component (64) connected to the rotor shaft (22); a damping structure (66) fixed at the first rotor component (62) or floated between the first and the second rotor component and having a contact surface (68) arranged to press against a contact surface (70) of the second rotor component (64) to damp a vibration of the second rotor component. Furthermore the invention is also directed to a method for damping.
