The invention relates to an opening system () for an auxiliary door () of an airplane in a fuselage (), the door and the fuselage having skins in the extension of one another. In one exemplary embodiment, the system () includes a framing lintel () integrated into the fuselage, an upper beam (S) of the door structure arranged opposite the lintel (), and a set of three lever links (A,B,C). Each link is connected, on the one hand, to the lintel () by a lever articulation () fixed relative to the fuselage () and, on the other hand, to the upper beam (S) by a lever articulation () mobile with the door (), the articulations () being connected respectively to the lintel () and to the upper beam (S) by fittings (). The set of links includes two types of link mounted alternately, in which the mobile articulation () remains positioned respectively close to the fuselage skin () and further from this skin (), the articulations () of two adjacent levers (A,B;B,C) forming an evolving quadrilateral.

Aircraft door opening system

An aircraft electric door for a pressurized airframe having a locking system for locking a safety catch, a system for moving a door arm, and an electric motor activated by a door computer to actuate both systems. The system for moving the door arm includes a guideway linked to the door arm. The guideway is in a mobile cylindrical support rotated by the electric motor. A fixed guide is fitted in a cylindrical sleeve around the cylindrical support. The fixed guide includes a vertical camway and a horizontal camway. The door arm pivots around a vertical hinge and is linked with door lifting devices. The door lifting devices are mounted between a shaft of the safety catch and the door arm.

Locking and moving system for an aircraft electric door

An aircraft electric door including a locking system for actuating a safety catch for locking the door, a system for moving the door between open and closed positions, and a single electric motor for actuating both the locking system and the system for moving the door.

The objective of the invention is to replace the rope bar of the door evacuation slide with individual connections. According to a preferred embodiment, the mechanism for arming/disarming an aircraft door evacuation slide () includes two releasable connectors () disposed to either side of the base of the door and each includes two half connectors (), a so-called upper half connector () rigidly connected to the door () and having an attachment device () for attachment to the slide, and a so-called lower half connector () fixed to the cabin floor (). Each upper half connector () includes a movable inner part controlled by a ring () and housed in the corresponding lower half-connector (). The mechanism can also include an electric motor coupled to two rods (), each rod () being capable of rotating the control ring () of each upper half connector () between two angular positions: an armed position and a disarmed position.
