Integrally bladed rotor having an MMC ring component and an airfoil component having monolithic airfoils

摘要

An integrally bladed rotor is provided. This rotor includes a ring component (20), wherein the ring component (20) further includes at least one metal matrix composite and a plurality of radially outwardly facing blade conical surfaces (24); an airfoil component (10), wherein the airfoil component (10) further includes: a plurality of individual airfoil blades, wherein each of the plurality of airfoil blades further includes a radially inwardly facing blade conical surface (14); wherein the ring component and the airfoil component have been frictionally engaged to effect an inertia weld therebetween along the conical surfaces (14,24).
