Aircraft partition designed to separate a cargo part from a cockpit or from a passenger compartment
View Patent ↗A partition for an aircraft is designed to separate a cargo part from a cockpit or a passenger compartment of this aircraft. The partition includes a cellular central structure in contact with a first external wall and a second external wall of this partition. The partition also includes several stiffener elements added onto at least one of the first and second external walls. The invention also relates to an aircraft including at least one such partition.
1. A partition for an aircraft designed to separate a cargo part from a cockpit or a passenger compartment of said aircraft, said partition comprising a cellular central structure in contact with a first external wall and a second external wall of said partition, said cellular central structure including partition elements each in the form of a plate and arranged approximately parallel to and perpendicular to each other, said partition elements forming cells each having two openings facing said first and second external walls, respectively, wherein said partition also comprises several stiffener elements added onto at least one of said first and second external walls, wherein said partition elements are not coplanar with said stiffener elements, and said stiffener elements extend substantially continuously, along at least one straight line, over substantially the entire height of said partition.
2. A partition for an aircraft according to claim 1 , wherein each of said first and second external walls is in the form of a plane plate.
3. A partition for an aircraft according to claim 1 or to claim 2 , wherein each stiffener element is in the form of a strip installed on one of said first and second external walls.
4. A partition for an aircraft according to claim 1 , wherein each stiffener element extends approximately along the direction of the height of said partition, matching one of said first and second external walls.
5. A partition for an aircraft according to claim 1 , wherein each stiffener element is installed on an internal surface of one of said first and second external walls of said partition.
6. A partition for an aircraft according to claim 1 , further comprising at least one secondary stiffener element added onto at least one of said partition elements.
7. A partition for an aircraft according to claim 1 , wherein said partition is made from aluminium or one of its alloys.
8. An aircraft comprising a fuselage and at least one partition separating a cargo part from a cockpit or a passenger compartment within said fuselage of said aircraft, wherein at least one partition separating a cargo part from the cockpit or a passenger compartment is a partition according to claim 1 .
9. An aircraft according to claim 8 , wherein said at least one partition is fixed to the fuselage of said aircraft only by an upper edge and a lower edge of said partition.
10. A partition for an aircraft according to claim 1 , wherein said first and second external walls are parallel to each other and said cellular central structure is between said first and second external walls.
11. A partition for an aircraft according to claim 10 , wherein a first plurality of said partition elements includes horizontal partition elements and a second plurality of said partition elements includes vertical partition elements, and wherein said horizontal and vertical partition elements are perpendicular to said first and second external walls.
12. A partition for aircraft according to claim 11 , wherein a first plurality of said stiffener elements are fixed to an internal surface of said first external wall such that said stiffener elements of said first plurality are between said first and second external walls.
13. A partition for aircraft according to claim 12 , wherein a second plurality of said stiffener elements are fixed to an internal surface of said second external wall such that said stiffener elements of said second plurality are between said first and second external walls.
14. A partition for aircraft according to claim 12 , further comprising secondary stiffener elements fixed to said horizontal and vertical partition elements.
15. A partition for aircraft according to claim 11 , wherein said vertical partition elements are U-shaped and have flanges that are fixed to said first and second external walls.
16. A partition for aircraft according to claim 11 , wherein said horizontal partition elements extend from said first wall to said second external wall.
17. A partition for aircraft according to claim 11 , wherein said stiffener elements are aligned with each other from one cell to another adjacent cell of said cellular central structure.
