Abstract (en)
[origin: EP1925781A1] A blade arrangement (1) has a rotor and several blades arranged around the periphery of the rotor in a crown. Between two directly adjacent blades at least two damping elements (5,7) are provided and during rotor rotation around an axis, adjacent damping elements make contact between them as caused by the centrifugal force acting in a radial direction, and one of the damping elements makes contact with one of the two blades and the other of the two damping elements (7,5) makes contact with the other blade. Two of the contacts are flat and one of the contacts is linear.
