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

Device () for controlling an airflow guiding system (), comprising at least one actuator () configured to translate a control rod () between a first and a second end position of a nominal operating range in which at least one vane () of the airflow guiding system () can be moved between a first and a second angle, the control rod () being connected to the vane () by a control lever () comprising a first control rod () and a second control rod () which are hinged together. 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 to orient the vane () at a safe pitch angle between the first angle and the second angle.
