MIXED-FLOW TURBINE WHEEL OF A TURBOCHARGER, AND EXHAUST GAS TURBINE COMPRISING A TURBINE WHEEL OF SAID TYPE

摘要

The invention relates to a mixed-flow turbine wheel (10) of a turbocharger, comprising a plurality of blades (14) that are distributed along the circumference of the turbine wheel (10); at least one blade (14) includes a leading edge (20) that has an at least partly curved axial-radial orientation with a varying blade angle β relative to an axis of rotation (12) of the turbine wheel (10); when viewed along the leading edge (20), the blade angle β has a minimum β_min in a central region between a hub end (26) and a casing end (28) of the blade (14).
