Abstract
A method for repairing a flange of a rotor, to a transverse surface of which a disk of a fan in an upstream turbo-fan engine is attached. The flange includes, in a form of a ring, openings for connecting to the disk and intermediate discharge openings. Wear marks are formed by friction of the fan blades on the flange. The method includes machining spot facings onto the flange, in areas with wear marks; placing anti-wear slugs in the discharge openings that can be covered by the blades during friction; and the spot facings extend between the connection openings and are circumferentially limited by clamping surfaces of the connection between the disk and the flange.
