Abstract
An axial compressor rotor assembly includes a plurality of rotor disks extending axially along and circumferentially about a central axis between an upstream end and a downstream end. The rotor disks extend radially between an inner radial hub and an outer radial rim, and axially between a forward rim end and a rearward rim end. An airfoil extends spanwise from each of the rotor disks. A first rotor disk is disposed forward of a second rotor disk. The second rotor disk includes an interstage shaft. The interstage shaft includes an outer radial end, an inner radial end, and an arm. The arm extending axially from an outer surface of the interstage shaft to a distal end. The rearward rim end of the first rotor disk is fixedly joined to the distal end of the arm, for example, by inertia welding.
