An assembly for arming/disarming a slide of an airplane door according to the invention comprises a system with two releasable connection mechanisms () linked with the door () and a cabin floor of the airplane, each mechanism () comprising a releasable connector () secured to the door (), extending at right angles to the floor on each side of a door bottom, and an anchor fitting () fixed to the cabin floor. Each connector () is equipped with an elastic centering element () and a locking/unlocking grab () on the corresponding anchor fitting (), the connectors () being linked by a girt bar (). Each grab () being rotationally mobile, one of the grabs () is driven by a single command () which drives the other grab in rotation via the girt bar ().

Method and system for arming/disarming an aircraft door slide and implementation assembly

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

The invention proposes a simple system, with small space requirement, without hinge arms or sealing skirt, while providing secure and effective opening. To achieve this, the invention provides a door opening by a lateral guidance defining an integrated doubling-back kinematics, towards the interior then the exterior of the fuselage. An opening system of an emergency door () is positioned in an aircraft fuselage (), the door and the fuselage comprising respective frameworks () extending opposite each other. According to the invention, the system comprises a control handle () for rotating, combined with a bolt/latch pair, and an opening mechanism () equipped, in the upper corner areas (Zs) of the door (), with a pivoting lever () hinged on an upper edge of the fuselage () and provided with guide tracks interacting with the bulk/latch pair and with a door attachment fitting (), upper and lower rollers mounted in the lateral framework of the door () in connection with the guide tracks () mounted in the opposing fuselage framework (), the upper guide tracks () being inclined rising towards the interior of the cabin (I) and the lower guide tracks () being curved.

Opening system and method for an aircraft emergency door

The invention relates to a guard for the upper part of a door () of an aircraft, consisting of: a composite comprising a composite and/or stainless steel strip () which forms the core of the guard () and which renders same flexible and resistant, a silicon which is optionally reinforced with fibres and a polyester.
