The invention concerns the field of turbomachines, and more specifically an annular element (13) of a turbomachine casing, comprising at least one inner face (14), delimiting a flow channel for the flow of a working fluid of the turbomachine, an outer face (15), and a damper (18), comprising at least one elastic coil (18a, 18b, 18c) clamped around a surface of revolution (15a) of the outer face (15), in such a way as to exert pressure against said surface of revolution (15a). The present invention also concerns the damping of a rotating wave deforming such an annular element (13) of a turbomachine casing, in which said rotating wave is damped by friction between said surface of revolution (15a) and the at least one coil (18a, 18b, 18c) of the damper (18). |
