Blade arrangement
Abstract:
A blade arrangement, with a rotor and a plurality of blades which are arranged on the periphery of the rotor in a ring, and a plurality of damping elements are provided. Between two directly adjacent blades at least two damping elements are arranged in series in the circumferential direction of the rotor. As a result of a centrifugal force, which acts in the radial direction, during a rotation of the rotor around a rotor axis adjacent damping elements come into contact with each other, and one of the two damping elements comes into contact with one of the two blades and the other of the two damping elements comes into contact with the other of the two blades.
