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 coord...

A fan rotor has a fan hub (10) and a plurality of circumferentially spaced-apart fan blades (11) extending radially outwardly from an outer rim (13) of the fan hub (10). The outer rim (13) is integrally connected to an inner rim (14) through an axially fac...

A combined fan-compressor impeller comprises a single hub and a plurality of spaced main blades extending outwardly from the hub such that an air passage channel is defined between two of the main blades. Each of the main blades is a mixed flow blade which...
