A blade fastening for the blades of compressors and/or turbines, especially for blades retained in dove-tail tangential grooves provided along the outer diameter of the rotor disks; the webs of the tangential grooves cover the hammer-head-like bases of the blades substantially over the entire rotor disk circumference while the blades provided with the hammer-head-like bases are adapted to be inserted by rotation into the tangential groove provided with small apertures; in order to fix the blades in a predetermined position relative to the rotor disk diameter, filler, clamping and locking elements are provided. |
