Device for sealing a joint between a wing box and a central fuselage of an aircraft, corresponding sealing processes and corresponding aircraft

A device for sealing a joint between at least one wall of a wing box of an aircraft and at least one wall of a central fuselage of said aircraft, said device comprising:

• at least one deformable element having a main bore, said at least one deformable element configured to come into contact with said at least one wall of said wing box and said at least one wall of said central fuselage of said aircraft;
• a first rigid end element having a first bore and a second rigid end element having a second bore, said first bore and second bore extending coaxially with said main bore, said rigid end elements being disposed on either side of said at least one deformable element and configured to clamp said at least one deformable element;
• clamping means having a nut and a clamping screw, said nut having a tapped portion and being disposed against one of said first and second rigid end elements and said clamping screw having a screw head and a threaded shank, said screw head being disposed against the other of said first and second rigid end elements and said threaded shank being fitted in said main bore and in said first bore and said second bore so as to be screwed to said nut;
• and
• at least one intermediate rigid element disposed in said at least one deformable element or between at least two deformable elements when said device has a plurality of deformable elements, said at least one intermediate rigid element having a third bore extending coaxially with said first bore, in which said threaded shank is fitted;
• wherein said clamping means are configured to move between an inactive position, in which said clamping means do not clamp the first rigid end element and the second rigid end element towards one another and leave said at least one deformable element in an undeformed initial position, and a clamping position, in which said clamping means clamp the first rigid end element and the second rigid end element towards one another by deforming said at least one deformable element by crushing until said at least one deformable element is pressed against said at least one wall of said wing box and against said at least one wall of the central fuselage;
• and
• wherein said rigid end element against which said nut is disposed has a recess for receiving and holding said nut, preventing a rotation of said nut relative to said rigid end element during the clamping and unclamping of said clamping means.
