  • DYNAMICALLY ADJUSTABLE ROTORCRAFT SWASHPLATE WITH UNDULATING SURFACE
    Publication number: 20220332412
    Abstract: A rotorcraft swashplate assembly includes a rotationally fixed swashplate fixed against rotating with a rotorcraft rotor. The swashplate assembly also includes a rotatable swashplate coupled to the rotor to rotate with the rotor. The swashplate assembly also includes multiple pitch change links, each pitch change link coupled to a respective rotor blade and to the rotatable swashplate to rotate with the rotor. The swashplate assembly also includes an annular track coupled to the rotationally fixed swashplate and configured to support each pitch change link riding on the annular track as each pitch change link rotates with the rotor. The track includes multiple bearings upon which a pitch change link rides, and actuators that move the bearings changing a shape of the annular track and thereby the pitch of each rotor blade as each pitch change link rides on the annular track during rotation of the rotor blades.
