Abstract

In a turbine wheel of an exhaust gas turbine comprising a turbine wheel with a hub and a plurality of turbine wheel blades which are arranged on the turbine wheel hub and which extend axially between a turbine wheel inlet and a turbine wheel outlet, the turbine wheel blades are constructed in such a way that the ratio of the hub contour thickness to the external contour thickness of each turbine wheel blade follows a defined function.
