  • Fan rotor with construction and safety performance optimization
    Patent number: 6457941
    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.
    Type: Grant
    Filed: March 13, 2001
    Date of Patent: October 1, 2002
    Assignee: The United States of America as represented by the Secretary of the Navy
