Patent

CA 2711104

The invention relates to a method for actuating at least one regulating flap on each wing of an aircraft, which is actuated by at least two flap coupling devices (11, 12, 13, 14), each having one servo drive device (30), wherein at least one braking device per regulating flap is disposed at a servo drive device (30). By actuating the braking device, an adjusted state of the respective servo drive device (30) can be locked in position. The method comprises the following steps: actuating each braking device of a regulating flap individually; subsequently actuating the servo drive device by means of the drive motor; once the adjusted state of the regulating flap has been changed by a specified amount, the actuation of said regulating flap is concluded. The invention also relates to a system for implementing the method.

La présente invention concerne un procédé permettant d'actionner au moins un clapet de réglage au niveau de chaque aile d'un avion, lequel clapet est actionné par au moins deux dispositifs de couplage de clapet (11, 12, 13, 14) comprenant respectivement un dispositif actionneur (30). Un dispositif de freinage est placé au moins sur un dispositif actionneur (30) pour chaque clapet de réglage. L'actionnement de ce dispositif de freinage permet de bloquer un état de réglage de chaque dispositif actionneur (30). Le procédé selon l'invention consiste à actionner chaque dispositif de freinage d'un clapet de réglage de façon individuelle, puis à actionner le dispositif actionneur au moyen du moteur d'entraînement en cas de modification de l'état de réglage du clapet de réglage dans une certaine mesure, et à arrêter l'actionnement du clapet de réglage concerné. L'invention concerne également un système permettant de mettre en oeuvre ledit procédé.
