  • Blade for a variable pitch fan
    Patent number: 10364822
    Abstract: A fan blade is mounted on a shaft or arranged to vary in pitch via rotation about a pitching axis. The fan blade is mounted with a center of mass offset from the shaft or pitching axis. This offset reduces torque around the shaft or pitching axis.
    Type: Grant
    Filed: August 23, 2016
    Date of Patent: July 30, 2019
    Assignee: FLEXXAIRE INC
    Inventors: Jonathan E. McCallum, George Antoszko, Peter Knight

  • Variable pitch fan having a pitch sensor
    Patent number: 9086076
    Abstract: A compact variable pitch fan has a drive fluid pitch change mechanism. A pitch change piston is constrained to follow reciprocating motion under drive fluid control within a peripheral hub from which fan blades extend outward. A pitch change sensor is mounted with the rotary union.

  • Compact variable pitch fan
    Patent number: 8197214
    Abstract: A compact variable pitch fan has a hydraulic pitch change mechanism. A pitch change piston is constrained to follow reciprocating motion under hydraulic control within a peripheral hub from which fan blades extend outward. An additional feature is the use of separated guiding and seal surfaces. A still further feature is the use of a pitch sensor, particularly on the hydraulic line leading to the variable pitch fan.
