Title (EN) AN AIRCRAFT SECONDARY CONTROL SYSTEM FOR AIRCRAFT AND A METHOD FOR OPERATING THE SYSTEM
(FR) SYSTÈME DE COMMANDE SECONDAIRE D'AÉRONEF POUR AÉRONEF ET PROCÉDÉ D'ACTIONNEMENT DU SYSTÈME
Abstract:
(EN) The present invention regards a system and a method for providing a motion of an aircraft secondary control member (111, 611) incrementally in steps. An aircraft secondary control system comprises a rod arrangement (109, 609) of a driving actuator (115, 615), configured for performing the motion. The rod arrangement (109, 609) is coupled to the aircraft secondary control member (111, 611) via a linkage arrangement (117, 617). The driving actuator (115, 615) comprises a first engagement and disengagement device (119, 619) of a piston body (107, 607) and comprises a second engagement and disengagement device (125, 625), each of which being configured for alternately and/or simultaneously engaging said rod arrangement (109, 609). The piston body (107, 607) is arranged in a cylinder body (105, 605) and is configured to make a working stroke from a first position (P1) to a second position (P2). There is provided a method of engaging the piston body (107, 607) to the rod arrangement (109, 609); moving the piston body (107, 607) together with the rod arrangement (109, 609) a distance corresponding with said working stroke; engaging the second engagement and disengagement device (125, 625) to the rod arrangement (109, 609); disengaging the first engagement and disengagement device (119, 619) from the rod arrangement (109, 609); retracting the piston body (107) from the second position (P2) to the first position (P1) and repeating the previous method steps for providing said motion.
(FR) La présente invention concerne un système et un procédé permettant de fournir un mouvement d'un élément de commande secondaire d'aéronef (111, 611) par étapes incrémentielles. Un système de commande secondaire d'aéronef comprend un agencement tige (109, 609) d'un actionneur d'entraînement (115, 615), configuré pour effectuer le mouvement. L'agencement tige (109, 609) est accouplé à l'élément de commande secondaire d'aéronef (111, 611) par l'intermédiaire d'un agencement tringlerie (117, 617). L'actionneur d'entraînement (115, 615) comprend un premier dispositif d'engagement et de dégagement (119, 619) d'un corps de piston (107, 607) et comprend un deuxième dispositif d'engagement et de dégagement (125, 625), chacun d'entre eux étant configuré pour s'engager alternativement et/ou simultanément avec ledit agencement tige (109, 609). Le corps de piston (107, 607) est agencé dans un corps de cylindre (105, 605) et est configuré pour effectuer une course de travail d'une première position (P1) à une deuxième position (P2). L'invention concerne un procédé consistant à engager le corps de piston (107, 607) avec l'agencement tige (109, 609) ; à déplacer le corps de piston (107, 607) conjointement avec l'agencement tige (109, 609) d'une distance correspondant à ladite course de travail ; à engager le deuxième dispositif d'engagement et de dégagement (125, 625) avec l'agencement tige (109, 609) ; à dégager le premier dispositif d'engagement et de dégagement (119, 619) de l'agencement tige (109, 609) ; à rétracter le corps de piston (107) de la deuxième position (P2) à la première position (P1) et à répéter les étapes précédentes du procédé pour fournir ledit mouvement.
