Abstract: A rotor blade (1) for a flow machine includes an aerodynamic blade (2) and a foot (3). The foot (3) has an anchoring section (5) on a side facing away from the blade (2). A rotor (4) of the flow machine has an axial anchoring groove (6) which is complementary to the anchoring section (5). The anchoring section (5) can be inserted axially into the anchoring groove (6) in order to radially attach the rotor blade (1) to the rotor (4). At least one pulling-off contour (7) is formed on the foot (3), via which an axial pulling-off force can be introduced into the rotor blade (1), which is attached to the rotor (4) with the aid of a pulling-off tool (15) which is complementary to this pulling-off contour (7).

Abstract: A method and apparatus for suppressing vibration in turbine blading and the like is disclosed. A damping tube is inserted through an aperture in each of a plurality of turbine blades. By expanding the damping tube after it is inserted in the blades the tube is firmly secured to each blade. A wire may be inserted through the damping tube and is secured by crimping the expanded tube portions. The tube may be divided into circumferential segments with each tube being widened for example by means of a center punch at an end portion which extends through the final blade of each segment.
