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 emergency exit door () with opening mechanisms integrated by a grouping of the mechanisms into a door beam () located on a given side of a window () of standard dimensions. In the beam, an inner handle () is mounted on a main shaft () connected with a locking shaft (A) on which there is mounted, against return springs (), a door blocking/locking mechanism () comprising a lock (). A mechanism for conditionally opening the door () includes a vent flap (), a pivot connection () for coupling the flap () to the inner handle (), and a blocking shaft () that has, at each end, a pressure lever () equipped with supports for blocking () and unblocking () the flap (). Return springs () mounted against the conditional opening mechanism () are calibrated to allow the opening of the flap () by exerting reduced pressure in residual pressure variation conditions, and to prevent it from opening in overpressure conditions.

Aircraft emergency exit door with integrated mechanisms and method for opening/closing such a 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.

Apparatus for opening and closing an aircraft electric door

The invention aims to make aircraft doors easier to open by preventing ice formation or, at the very least, favoring rapid breaking of the ice on the door edges connected to the skin of the fuselage. To that end, it is provided to supply energy along the door when specific conditions are met. According to one embodiment, an anti-icing/de-icing system for an aircraft door () according to the invention includes an excitation energy source and devices (to) for dissipating such energy extending parallel to a side surface () of the aircraft door (), along a sealing gasket () support () secured to the door () across from a fuselage () side surface () framing () the door (). The sealing gasket () of the door () is compressed against bearing () from a side surface () of the fuselage () when the door () is closed.

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.
