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 an inducer portion and an exducer portion, where, in the inducer portion, in a direction outwardly from the hub, each of the blades includes positive lean angles, a zero lean angle and negative lean angles and where, in the exducer portion, in a direction outwardly from the hub, each of the blades includes negative lean angles, a zero lean angle and positive lean angles.
