Abstract
A turbocharger turbine wheel can include a hub that includes a rotational axis, a backdisk and a nose, where the rotational axis defines an axial coordinate (z) in a cylindrical coordinate system that includes a radial coordinate (r) and an azimuthal coordinate (Θ) in a direction of intended rotation about the rotational axis; and blades that extend outwardly from the hub, where each of the blades includes a leading edge and a trailing edge, where the leading edge includes a lower axial point defined by a first theta angle and an upper axial point defined by a second theta angle, where the first theta angle is greater than the second theta angle with respect to the direction of intended rotation of the turbine wheel.
