A system for forming a two-degree-of-freedom actuator, for example, a system for changing the pitch angle of a blade of a propeller during rotation

摘要

A two-degree-of-freedom actuator, for example, an actuator for a multi-blade rotor in an aircraft, comprising at least two blades that are rotationally driven around a main axis of rotation by a first actuator, and each of the blades in a longitudinal axis of each blade. A second actuator centered on the main axis based on the azimuth of the rotor to have a predetermined cyclic pitch of a given amplitude of each blade according to the azimuth of the rotor It has synchronization means operatively arranged to drive.
