Abstract
A divergent segment includes a stationary divergent portion and a movable divergent portion suitable for occupying a retracted position and a deployed position. The threaded rod has a head supported by a support secured to the stationary divergent portion in cooperation with a rotary drive for driving the threaded rod in rotation, and a tip suitable for being inserted in a holder sleeve secured to the stationary divergent portion. The threaded rod cooperates with a nut secured to the movable divergent portion so that rotation of the rod causes the movable divergent portion to move. The tip presents an enlargement having at least one groove passing axially therethrough.
