Abstract (en)
The damper (10) has a base plate (13) supported on a disk rim of a rotor of a turbomachine e.g. high pressure gas turbine engine axial compressor, and a spring plate (12). The plate (12) connects an elongated conterweight (11) with the plate (13), where the counterweight is made of composite material i.e. impregnated fabric. The counterweight has contact surface portions that are contacted with platforms of vanes. The portions form an angle that is lower than 90 degree, with the plate (13), when the plate (12) is at rest.
