Abstract
A system changes the pitch of blades of a turbine engine propeller having a plurality of blades. The system includes a plurality of links, each link being connected to one of the propeller blades at a first interface, and a control means acting on the link and having a body movable in translation along a longitudinal axis. A load transfer module is arranged between the links and the control means and is connected to the links at a plurality of second interfaces. A first adjustment element is configured to adjust an axial position of the second interfaces along the axis to provide adjustment of the pitch of all of the blades simultaneously. A plurality of second adjustment elements are configured to adjust an axial distance between each first interface and the corresponding second interface to allow the pitch of each blade to be adjusted individually.
