A radial-flow rotor consisting of a disk and exactly radial blades experiences normal stresses in radial and circumferential direction and shear stresses by virtue of centrifugal forces and the torque, respectively. The following investigation is restricted to the analysis of the effect of the centrifugal forces, primarily because this is the predominant effect at high speeds at least so long as the rotor is not subjected to torsional vibrations. Special attention is being paid to the mutual interference of disk and blades.
