Pitch-change system equipped with means for adjusting blade pitch and corresponding turbine engine

A pitch change system for changing the pitch of blades of at least one turbine engine propeller provided with a plurality of blades, the system comprising:

• a plurality of links, each link corresponding to one of the blades and being connected to the corresponding blade to define one of a plurality of first interfaces;
• a control means acting on each link and having a movable body and a fixed body, the movable body being translatable along a longitudinal axis relative to said fixed body and the movable body being arranged around the fixed body and being coaxial with the longitudinal axis;
• a load transfer module arranged between the plurality of links and the control means, each link being connected to the load transfer module to define one of a plurality of second interfaces;
• and
• means for adjusting the setting of the blades, comprising:
• a removable first adjustment element arranged between the load transfer module and the movable body and configured to adjust simultaneously an axial position of each of the plurality of second interfaces along the longitudinal axis and to adjust in a common way the plurality of blades, and
• a plurality of second adjustment elements, each second adjustment element corresponding to one of the plurality of links and being configured to adjust an axial distance along the longitudinal axis between the first and second interfaces of the corresponding link.
