Claim 14:
15. A method of manufacturing a rotor that defines an axis of rotation for a turbomachine, the method comprising:
providing a first lug with a first lug body and a first interface material disposed on the first lug body;
providing a second lug with a second lug body and a second interface material disposed on the second lug body;
friction welding the first lug to a first hub member using the first interface material, thereby defining a first projected structure for an outer radial area of a disc assembly of the rotor, the first projected structure including a first side;
friction welding the second lug to a second hub member of the disc assembly using the second interface material to define a second projected structure for the outer radial area of the disc assembly of the rotor, the second projected structure including a second side that is spaced apart from the first side in a circumferential direction relative to the axis of rotation to at least partly define a space for a rotor blade;
removably attaching the rotor blade to the disc assembly within the space;
the first lug body and the first hub member made from different materials; and
the second lug body and the second hub member made from different materials.
