Abstract:
A method for manufacturing a rotor shaft, said method comprising:fabricating a first shaft portion from a first material such that the first shaft portion extends axially from a first end to a second end; fabricating a second shaft portion from a second material that is different from the first material, such that the second shaft portion extends axially from a first end to a second end; coupling the second shaft portion to the first shaft portion with an explosive bonded joint such that the second shaft portion is aligned substantially concentrically with respect to the first shaft portion, and such that the bonded joint extends obliquely with respect to a centerline axis of symmetry of the rotor shaft; and extending a layer of material within the bonded joint to separate the first shaft portion from the second shaft portion, wherein the layer of material is fabricated from a material that is different than the first and second materials.
