  • Rotary wing aircraft pitch control system
    Patent number: 10676185
    Abstract: A pitch control system configured to vary a pitch angle of at least one of a plurality of propeller blades of a propeller system is provided including a switch movable between a neutral position and a plurality of non-neutral positions. Movement of the switch to a first non-neutral position generates a command to move the propeller blades in a first direction. Movement of the switch to a second non-neutral position generates a command to move the propeller blades in a second direction. Movement of the switch to a third non-neutral position generates a command to move the propeller blades to a zero thrust position.
    Type: Grant
    Filed: August 27, 2015
    Date of Patent: June 9, 2020
    Assignee: SIKORSKY AIRCRAFT CORPORATION
