Patent abstract
The hub/blade junction of each rotor blade is placed with respect to the scalloping surface (F1+F2) such that this surface is supported as symmetrically as possible by the rotor blade. The turbine wheel with three-dimensionally curved rotor blades has scalloping in the area of the hub rear wall, and in consequence is subject to reduced stresses caused by scalloping deformation.
