ABSTRACT:
In a bladed rotor of an axial-flow turbomachine, the blades essentially consist of a blade body and a blade root. They are fastened with their blade roots in rows in encircling blade grooves having lateral supporting prongs. A shoulder serving to assemble the blades on the rotor is attached between blade body and blade root. The blade grooves are shaped symmetrically to the associated planes of symmetry by a plurality of radii (R1-R4), the preceding radius (R1) in each case being larger than the following radius (R2). The circular arcs formed by the radii (R1-R4) have a common tangent (T) at their contact points.
