System for manufacturing a rotor having an MMC ring component and an airfoil component having MMC airfoils
A system for manufacturing an integrally bladed rotor is provided. This system includes a ring component, wherein the ring component further includes at least one metal matrix composite and a continuous radially outwardly facing conical surface; an airfoil component, wherein the airfoil component further includes a plurality of individual airfoil blades, wherein at least a portion of each individual airfoil blade has been reinforced with at least one metal matrix composite, and wherein each of the plurality of airfoil blades further includes a radially inwardly facing blade conical surface; and inertia welding means for frictionally engaging under an axially applied weld load the ring component and the airfoil component to effect an inertia weld therebetween along the conical surfaces.
