Abstract (en)
[origin: WO2012072069A1] The invention relates to a damping means (2) for damping a blade movement of a turbomachine (1) and to a method for producing the damping means (2). The damping means (2) has at least one side surface (21, 21') which can be brought into frictional contact with a friction surface of the turbomachine (1) in order to damp a blade movement. The side surfaces (21, 21') are of asymmetrically convex configuration.
