Abstract:
1. A turbine wheel of a radial or mixed-flow turbine having a hub and rotor blades with each rotor blade being connected in each case along a curved hub/blade junction to the hub and with the rotor blades being designed and arranged on the hub such that the hub/blade junction runs curved towards the pressure side of the rotor blades, deviating from the radial direction, with the hub having a scalloping contour between, in each case, two adjacent rotor blades in the area of a hub rear wall, with a hub surface (F with a radial line which bisects the hub surface (F wherein the terminal ends of the hub/blade junction of each rotor blade is in each case arranged offset towards the pressure side of the rotor blade with respect to the intersection point (C), and wherein the hub/blade junction of each rotor blade equally divides into two halves the hub surface (F
