Abstract (en)
[origin: US2018112674A1] A compressor rotor of a turbomachine includes a rotor disk; a rotor hub forming or connected to a radially outer edge of the rotor disk; and a plurality of rotor blades on the rotor hub extending radially outwards. The rotor hub includes an axially frontal leading edge, an axially rear trailing edge, a top side, a frontal bottom side extending on a bottom side of the rotor hub from the leading edge in a direction of the rotor disk and transitioning into same, and a rear bottom side extending on the bottom side from the trailing edge in the direction of the rotor disk and transitioning into same. The frontal bottom side and/or the rear bottom side of the hub is contoured in a circumferential direction of the rotor hub to form respectively one indentation in an area below a rotor blade.
