Abstract

Dispositif (30) de commande d’un système de guidage du flux d’air (20) comprenant au moins un actionneur (31) configuré pour entrainer en translation une tige de commande (32) entre une première et une deuxième position extrême d’une plage nominale de fonctionnement dans laquelle au moins une aube (21a) du système de guidage du flux (20) est mobile entre un premier et un deuxième angle, la tige de commande (32) étant reliée à l’aube (21a) par un levier de commande (33) comportant une première biellette de commande (36) et une deuxième biellette de commande (37) articulées l’une par rapport à l’autre. L’actionneur (31) est configuré pour amener la tige de commande (32) dans une position de sécurité située au-delà de la deuxième position extrême de la plage nominale de fonctionnement et orienter l’aube (21a) d’un angle de calage sécuritaire compris entre le premier angle et le deuxième angle. Le dispositif (30) de commande comprend un organe (40) de guidage de la tige de commande (32) configuré pour guider ladite tige selon une courbe guide lors du déplacement de ladite tige dans la plage nominale de fonctionnement. Figure pour l’abrégé : Fig 3Device (30) for controlling an airflow guidance system (20) comprising at least one actuator (31) configured to drive a control rod (32) in translation between a first and a second extreme position of a nominal operating range in which at least one vane (21a) of the flow guiding system (20) is movable between a first and a second angle, the control rod (32) being connected to the vane (21a) by a control lever (33) comprising a first control link (36) and a second control link (37) articulated relative to each other. The actuator (31) is configured to bring the control rod (32) into a safety position located beyond the second extreme position of the nominal operating range and orient the vane (21a) through an angle of secure wedging between the first angle and the second angle. The control device (30) comprises a member (40) for guiding the control rod (32) configured to guide said rod according to a guide curve during the movement of said rod in the nominal operating range.
