Abstract
In a succession of rotor disks, only the end disks are connected to a main structure by bolted extensions and the intermediate disks are suspended from rigid spacer pieces by centering and anti-rotation connections. The end disks are interconnected to clamp the assembly in the axial direction. There is no bolted connection between the successive disks. Assembly is very easy. The disks and the spacer pieces are stacked together in alternately, and the assembly is torsionally very rigid because of the use of a high number of claw-coupling teeth formed by protruding ends of the blade roots forming teeth that engage in spacer piece end rims.
