Patent abstract
A rotor assembly or “blisk” for a gas turbine engine includes a metallic hub having an annular flowpath surface, and at least one blade extending outwardly from the flowpath surface. The blade includes a metallic body having a first density. The metallic body defines a shank portion and an airfoil portion having opposed pressure and suction sides, and is integral with the hub. An insert having a second density less than the first density is carried by the body, and the insert and the body collectively define an airfoil shape. A method is also provided for manufacturing a rotor assembly.
