Abstract: A rotor blade (14) for a turbine engine rotor assembly (10) is provided with apparatus for damping vibrations in the blade. The blade includes a pocket (26) formed in a surface. The apparatus for damping vibrations in the blade includes a damper (34) and a pocket lid (36). The damper (34) is received within the pocket (26) between an inner surface (32) of the pocket (26) and the pocket lid (36). The pocket lid is attached to the airfoil and contoured to match the curvature of the airfoil. The damper may be of a sinusoidal shape, or may comprise a plurality of strands (39) formed in a mesh (38).
