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 that defines an axis of rotation for a turbomachine, the method comprising:
- providing a lug with a lug body and an interface material disposed on the lug body;
- friction welding the lug to a hub member using the interface material, thereby defining a projected structure for an outer radial area of a disc assembly of the rotor;
- disposing the projected structure proximate another projected structure that projects from the disc assembly, the projected structure and the other projected structure spaced apart 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;
- and
- the lug body and the hub member made from different materials.
