Embodiment Construction

[0054] Such as figure 1 The aircraft shown and designated by the general reference numeral 10 includes a fuselage 12 and a plurality of doors and hatches 14 , 16 , 18 , 20 , 21 for onboard access.

[0055] The invention is particularly applicable to aircraft doors through which passengers and crew enter and exit the aircraft, as well as other opening / closing doors or hatches (pallet compartments, bulk compartments, etc.) through which luggage, cargo and food are brought onto the aircraft.

[0056] These various doors and hatches are susceptible to damage when the aircraft is on the ground.

[0057] In practice, airport equipment and facilities for cargo handling and for boarding and disembarking personnel may collide with the fuselage of the aircraft during close maneuvers.

[0058] The area subject to collision is the area around the doors, hatch covers, hatches, etc. used for entering and exiting the aircraft.

Abstract

Aircraft comprising at least one door (14, 16 P1) for passengers to board the aircraft, characterized in that it comprises at least one interconnection device (20; 40; 50; 60; 70) connecting an aircraft internal structure component (24) and a skin of the fuselage (22) of the aircraft, the interconnection device being positioned near the internal periphery of the door in a region (Z1) subject to external knocks and comprising at least one region that is weakened in terms of compression (26c; 42a; 42b; 62b; 62c; 62d; 72b; 74b) so as to absorb the knocks experienced by the external face of the skin of the fuselage, the device also being configured to withstand tensile forces applies to the internal face of the skin of the fuselage by the internal pressure inside the aircraft.

Description

technical field [0001] The invention relates to a connection device between an aircraft internal structure part and an aircraft fuselage skin. Background technique [0002] An aircraft fuselage is generally formed by a fuselage skin reinforced by structural parts such as longitudinal stiffeners (stringers) and transverse stiffeners (frames). The longitudinal reinforcements are joined to the skin by different assembly techniques: welding, riveting, etc. [0003] As for the transverse reinforcements, they are connected to the skin by clamps. [0004] Aircraft may sustain damage from their external environment while they are on the ground. [0005] Thus, for example, runway vehicles driving around the aircraft, such as crew loaders or transbordeurs de palettes, can cause collisions with the fuselage of the aircraft. [0006] The same is true for airport equipment such as gangway for boarding and disembarking. [0007] Most collisions occur in the surrounding environment nea...
