Rotor disk including a plurality of hooks

Method of repairing a rotor disk comprising a plurality of circumferentially distributed hooks, each hook having:

• a first element starting on a transverse flank of said rotor disk and extending along the longitudinal axis of said rotor disk,
• a second element starting at the end of said first element, said second element extending radially in the direction of the longitudinal axis of the rotor disk,
• the set of hooks defining an annular groove adapted to cooperate with at least two flange sectors, said repair method comprising:
• delimit a zone of the second element in which there are cracks,
• machine below the internal radius of curvature at the junction between the first element and the second element of the hook, a recess opening up at each of the transverse flanks of the second element and at the internal peripheral surface of the second element,
• the recess at least covering said zone such that the cracks are eliminated.
