Abstract:
Articulation device for a panel of an aircraft door on a jamb of the said door, the said device comprising a mechanism connecting the jamb to the panel, to define a trajectory followed by the said panel, outside the aircraft, when the panel is opened and closed, and orientation means capable of maintaining an approximately constant orientation of the panel when it is displaced along the said trajectory, in which the said mechanism defines a trajectory with a variable curvature comprising mainly a first part with a relatively large radius of curvature, said first part of the trajectory being approximately perpendicular to the panel, including a closed state of the said panel, and a second part of the trajectory with a relatively small radius of curvature, said second part being approximately parallel to the said panel and including a fully open state of the panel; in which the said mechanism comprises a main arm that can be articulated on the jamb by a first axis, at least one secondary arm articulated on the main arm by a second axis and that can be articulated on the panel by a third axis, and at least one control lever that can be articulated on the jamb by a fourth axis located close to the first axis and articulated on the secondary arm by a fifth axis located close to the second axis; and, in which the fourth axis is offset towards the outside of the aircraft with respect to the first axis and the fourth axis is offset towards the outside of the aircraft and towards the first axis with respect to the second axis.
