  • Fan rotor design for coincidence avoidance
    Publication number: 20070020101
    Abstract: A fan rotor capable of avoiding coincidence will include a fan hub comprising one or more slots each designed to receive a fan blade; and one or more fan blades disposed within the slots. One or more slots will comprise an Rz? baseline and have one or more second fan blades disposed therein while another set of slots will have an Rz baseline having one or more first fan blades disposed therein.
