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.

Abstract: A system changes the pitch of blades of at least one turbine engine propeller provided with a plurality of blades. The system includes a link mechanism connected to the propeller blades at a first interface, and a control means acting on the link mechanism and having a body movable in translation along a longitudinal axis. A load transfer module is arranged between the link mechanism and the control means. The load transfer module is connected to the link mechanism at a second interface. The system further includes means for adjusting the setting of the blades, the adjustment means having first adjustment elements configured to adjust an axial position of the second interface along the axis. The adjustment means also includes second adjustment elements configured so as to adjust an axial distance along the axis between the first interface and the second interface.
