A method for repairing a rotor system () of a turbomachine, having a rotor () which has a groove () extending in the circumferential direction () of the rotor for accommodating an annular section (). The method has the following steps: chamfering a notch () in the groove (); introducing a recess () into the groove (); and inserting the annular section () into the groove (). At least one engagement element () formed on the annular section () engages in the recess () in order to form a lock against rotation in the circumferential direction ().

Method for repairing a rotor system of a turbomachine, annular element for a rotor system of a turbomachine, and rotor system for a turbomachine

A method is disclosed for the repair of a component of a turbomachine, in particular a rotor of an aircraft gas turbine, with blades taken up in at least one groove and with at least one support region for limiting a blade tilt angle, whereby at least one segment, which has been subjected to wear, of the support region of the component is removed, and a coating that can be introduced in the unit on at least one supporting surface of at least one blade is formed on the component for limiting the blade tilt angle. In addition, a component of a turbomachine, in particular a rotor of an aircraft gas turbine, with at least one such repair site is disclosed.
