An aircraft door architecture having: a door (); an ejector (); an inflatable evacuation device (); an emergency energy source () connected to the ejector () and to the inflatable evacuation device (); a control unit () having the two following operating states: a nominal operating state in which the inflatable evacuation device () is kept in its retracted position and the emergency energy source is deactivated; an emergency operating state in which the emergency energy source () activates the actuation device of the ejector () in an emergency opening mode of the door (), and activates the inflation device of the inflatable evacuation device () in an emergency inflation mode.

Aircraft door architecture comprising an emergency energy source

Aircraft door designed to assume a first configuration and a second configuration, having a bistable mechanism biasing the aircraft door towards either the first or second configuration, the bistable mechanism including: a first yoke having a base attached to the first member and a first pivot rotatably mounted on the base; a second yoke having: a base attached to the first member; a lever a first end of which is mounted so as to pivot on the base; a second pivot mounted so as to rotate on the second end of the lever; a coupling device for coupling the lever to the second member of the door; an arch which can be elastically deformed by bending and a first end of which is attached to the first pivot and a second end attached to the second pivot.

Bistable mechanism for an aircraft door

Double-curved aircraft door having a pair of stops in contact over a contact area. The isobarycentre (A) of each contact area of a first lateral edge is substantially arranged in a first plane perpendicular to the longitudinal axis () and the same applies to a second lateral edge. For each contact area, the normal to the contact area passing through its isobarycentre (A,B) substantially passes through the axis () of a medium cylinder (). For each contact area, the normal to the contact area passing through its isobarycentre (A,B) forms a deflection angle with a plane perpendicular to the longitudinal axis (), the deflection angles of all the contact areas being equal.

Double-curved aircraft door with optimised locking means

A device for emergency opening of an aircraft door having: a tubular actuating member () which includes a first end plate () and a second end plate (); an elastic compression device having a tubular spring () compressed between the first end plate () and the second end plate (); an expansion regulator () arranged inside the tubular spring (); a retaining member which includes at least one peripheral attachment connecting the first end plate () to the second end plate (), the peripheral attachment being radially outside the tubular spring ().
