Abstract

An axial compressor rotor assembly (52) includes a plurality of rotor disks (76) extending axially along and circumferentially about a central axis (53) between an upstream end (54) and a downstream end (56). The rotor disks (76) extend radially between an inner radial hub (78) and an outer radial rim (84), and axially between a forward rim end (92A) and a rearward rim end (92B). An airfoil (80) extends spanwise from each of the rotor disks (76). A first rotor disk (76) is disposed forward of a second rotor disk (76). The second rotor disk (76) includes an interstage shaft (106). The interstage shaft (106) includes an outer radial end (108), an inner radial end (110), and an arm (130). The arm (130) extending axially from an outer surface (124) of the interstage shaft (106) to a distal end (132). The rearward rim end (92B) of the first rotor disk (76) is fixedly joined to the distal end (132) of the arm (130), for example, by inertia welding.
