Abstract
A fan rotor for a gas turbine engine has a fan hub mounted for rotation about a central axis of the engine. A plurality of fan blades are circumferentially distributed about a radially outer surface of an outer rim section of the fan hub. The outer rim section is connected to an inner rim section through an axially facing web section. The web section extends from the outer rim section at a location axially aft of the center of gravity of the fan blades. A ridge formation extends radially inwardly from the outer rim axially forward of the web section.
