Abstract:

A one-piece fan rotor optimized for construction and safety performance criteria is provided. The rotor has a hub with a radial cross-section defined by an I-beam. A plurality of unequally-spaced rotor blades are disposed circumferentially around and extend radially outward from the hub. Each rotor blade has a root portion coupled to the hub with the root portion defined by a concave fillet circumventing the rotor blade. For rotational balance, at least one of the forward side and backside of the hub incorporates an axially extending pad. Methods are provided for controlling stress on the rotor and for balancing the rotor.
