Abstract
A system for reducing stress in a rotor includes a rotor body, a bore (34) extending axially through the rotor body, and a plurality of impeller vanes (40) radially disposed on the rotor body. Each impeller vane (40) includes a first end proximate to the bore (34), and an undercut feature (44) at the first end of each impeller vane (40) removes a portion of each impeller vane (40) proximate to the bore (34). The present invention may also include a method for reducing stress in a rotor that includes machining an undercut feature (44) at a first end of a plurality of impeller vanes (40) disposed on a rotor body.
