Abstract:
A turbine wheel, in particular in a charging device for use in an internal combustion engine, is specified, wherein the turbine wheel (10) comprises a plurality of blades (12) on a hub (16) that forms a rear wall (14), wherein adjacent blades (12) form an inlet surface (18) having two leading edges (20) and an outlet surface (22) having two trailing edges (24) and situated substantially axially inward, wherein a surface (26) of a blade (12) is configurable by way of an angle (T) and a length (Z0) of a plurality of curvatures (30, . . . , 38) situated next to one another between the leading edge (20) and the trailing edge (24), wherein, for each of the curvatures (30, . . . , 38), the angle (T) of the leading edge (20) initially increases or remains constant and then decreases as the length (Z0) increases so as to form a maximum (40, 40′, 40″).
