Abstract
A rotor for a turbomachine and a method of manufacturing the same. The method includes providing a lug with a lug body and an interface material disposed on the lug body. The method also includes friction welding the lug to a hub member via the interface material to define a projected structure for an outer radial area of a disc assembly of the rotor. The projected structure is configured to support a first side of a rotor blade of the rotor in cooperation with a second projected structure of the disc assembly supporting a second side of the rotor blade. The lug body and the hub member are made from different materials.

A method of manufacturing a rotor for a turbomachine comprising:
- providing a lug with a lug body and an interface material disposed on the lug body;
- and
- friction welding the lug to a hub member via the interface material to define a projected structure for an outer radial area of a disc assembly of the rotor, the projected structure configured to support a first side of a rotor blade of the rotor in cooperation with a second projected structure of the disc assembly supporting a second side of the rotor blade, the lug body and the hub member made from different materials.
A disc assembly for a rotor of a turbomachine comprising:
- a hub;
- a plurality of lugs that are attached to the hub, the plurality of lugs projecting radially from the hub and spaced apart in a circumferential direction to define a blade space for a rotor blade of the rotor;
- at least one of the plurality of lugs being metallurgically bonded to a hub member of the hub to define a respective projected structure of the disc assembly, the at least one of the plurality of lugs including a lug body and an interface material that is metallurgically bonded to the lug body at a first bond interface, the interface material being welded to the hub member at a weld joint, the first bond interface disposed outboard radially of the weld joint;
- and
- the lug body and the hub member made from different materials.
