Abstract: An assembly (58) for a gas turbine engine (20) includes a compressor rotor (38), a turbine rotor (40) and a cooling circuit (60). The compressor rotor (38) includes a gas path surface (68). The turbine rotor (40) is rotatable with the compressor rotor (38) about a rotational axis. The cooling circuit (60) includes an inlet (102) in the gas path surface (68). The cooling circuit (60) extends from the inlet (102), through the compressor rotor (38) and into the turbine rotor (40).

Abstract: A rotor includes a blade (112), a hub (114) connected to a radially inner edge (122) of the blade, an outlet (136), and a channel (138). The blade includes a first side (124) between a leading edge (116) and a trailing edge (118) and a first channel inlet (128) in the first side of the blade. The outlet (136) is in a radially inner surface (134) of the hub. The channel (138) is between the first channel inlet (128) and the outlet (136).

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 hub profile, a shroud edge, a leading edge, a trailing edge, a pressure side, and a suction side, where the hub profile includes a global maximum radius and a global minimum radius, and where, between the global maximum radius and the global minimum radius, in an axial direction from the backdisk to the nose, the hub profile includes a local minimum radius at a first axial coordinate position and a local maximum radius at a second axial coordinate position.
