Device for controlling an airflow guiding system, in particular in an aircraft turbine engine

A device for controlling an airflow guiding system comprising at least one vane movable in rotation about an axis of rotation between a first angle and a second angle, the control device comprising at least one actuator configured to drive a control rod in translation between a first end position and a second end position of a nominal operating range in which the vane is movable between the first angle and the second angle, the control rod being linked to the axis of the vane by a control lever hinged with respect to a free end of the control rod opposite to the end linked to the actuator, characterized in that:

• the control lever comprises a first control connecting rod and a second control connecting rod, said first connecting rod comprising a first end hinged with respect to the free end of the control rod and a second end hinged with respect to a first end of the second connecting rod, said second connecting rod further comprising a second end, opposite to the first end and secured in rotation with the vane, and in that:
• the actuator is configured to bring the control rod into a safety position located beyond the second end position of the nominal operating range and orient the vane by a safe pitch angle between the first angle and the second angle.
