Title (EN) DEVICE FOR UNLOCKING A LANDING GEAR IN A DEPLOYED POSITION AND A LANDING GEAR COMPRISING ONE SUCH DEVICE
(FR) DISPOSITIF DE DEVERROUILLAGE D'UN ATTERRISSEUR DANS UNE POSITION DEPLOYEE ET ATTERRISSEUR EQUIPE D'UN TEL DISPOSITIF
Abstract: front page image
(EN)The invention relates to a single device for locking and unlocking the locking member of a landing gear having a folding strut, comprising an unlocking device (6) including: a rotary actuator (62) having an axis parallel to a hinge axis of the connecting links (3a, 3b) of the stabilising member; a crank (63) connected to the shaft of the actuator; a pawl (64) hinged to the end of the crank and comprising a step (65); an oval knob (31) solidly connected to, and projecting from one of the connecting links of the stabilising member; and means for returning the pawl so that it presses against the oval knob. The actuator can be actuated between: a first angular position for which the oval knob is in contact with the pawl facing the step while the connecting links are substantially aligned, and a second angular position for which the pawl pushes back the oval knob, thereby moving the connecting links of the stabilising member out of alignment.
(FR)L'invention vise à proposer un dispositif simple de blocage et de déblocage de l'organe de verrouillage d'un atterrisseur à contrefiche briseuse comportant un dispositif de déverrouillage (6) comportant: -un actionneur rotatif (62) d'axe parallèle à un axe d'articulation des biellettes (3a, 3b) de l'organe de stabilisation, -une manivelle (63) reliée à l'arbre de l'actionneur, -un cliquet (64) articulé à l'extrémité de la manivelle et comportant un redan (65), -une olive (31) solidaire et saillante d'une des biellettes de l'organe de stabilisation, -des moyens de rappel du cliquet en appui vers l'olive, l'actionneur étant actionnable entre une première position angulaire pour laquelle l'olive est en contact avec le cliquet en regard du redan alors que les biellettes sont sensiblement alignées et une seconde position angulaire pour laquelle le cliquet a repoussé l'olive, provoquant le désalignement des biellettes de l'organe de stabilisation.
