ABSTRACT:
The pitch control mechanism (controlling the angular position) for stator blades in a turbojet may be adjusted separately for two adjacent stages of blades controlled by a common actuator10.To achieve this, the synchronization bar9located between the mechanisms leading to the two stages is inclined, this inclination being determined by a pin22and groove23connection with the casing, while another pin26and groove27connection is arranged between the synchronization bar9and one of the mechanisms. Strongly non-linear displacement laws between the two mechanisms may thus be controlled depending on the shapes and directions of the grooves.
