Original Abstract Submitted
A fan module having variable-pitch blades is configured for use with for a propulsion unit having a longitudinal axis. The fan module includes a rotary casing carrying the blades and a pitch-changing system. The pitch-changing system includes a control device that includes an annular actuator having a stationary body added onto the rotary casing and a body configured to translate with respect to the stationary body along the longitudinal axis. A linking mechanism includes a synchronizing ring coupled to the mobile body, connected to the blades and configured to be translated along the longitudinal axis by the mobile body so as to change the pitch of the blades. A feathering device includes fly-weights coupled to the ring by a connecting rod of which the ends include ball-and-socket joints.
