Abstract
Systems and methods are provided to control a rotor blade pitch. In one example, a system comprises a ratchet mechanism comprising a ratchet wheel configured to be rotated by a motor about a first axis. The ratchet mechanism comprises one or more followers each of which is coupled to the ratchet wheel. The ratchet wheel rotates the one or more followers in a first direction about the first axis when the ratchet wheel is rotated by the motor in the first direction about the first axis. One or more rotor blades rotate about the first axis. Each rotor blade is affixed to a respective follower. Each follower controls a pitch of the respective rotor blade based on a position of the follower relative to the ratchet wheel.
