Embodiment Construction

[0036] For the remainder of this description, the longitudinal axis corresponds to the axis extending from the nose cone to the tail cone of the aircraft. The transverse plane corresponds to the plane perpendicular to the longitudinal axis. The transverse and horizontal directions are perpendicular to the longitudinal direction and parallel to the ground when the aircraft is on the ground.

[0037] The longitudinal and vertical planes correspond to the planes containing the longitudinal direction and are parallel to the vertical direction when the aircraft is on the ground.

[0038] An element considered to be the front element is closer to the nose cone of the aircraft than another element considered to be the rear element.

[0039] An element considered to be an upper element is further from the ground than another element considered to be a lower element.

[0040] Figure 4 to Figure 6 A center wing box 30 is shown including an upper panel 32 , a lower panel 34 , a front...

Abstract

A method for producing a central wing box including an upper panel, a lower panel, a front longeron, a rear longeron and four corners, wherein at least one panel and one longeron are obtained from a single flat metal wall which is bent along a bending line at approximately 90° which corresponds to a corner connecting said panel to said longeron.

Description

technical field [0001] The invention relates to a method for manufacturing a center wing box. Background technique [0002] Such as figure 1 As shown, the structure of the aircraft comprises two subassemblies, on the one hand the fuselage 10 and on the other hand the wings 12 connected by a box structure 14 known as the central wing box. [0003] Such as figure 2 As shown, the central wing box 14 includes two panels, an upper panel 16 and a lower panel 18, on the one hand, and two longitudinal beams, a front longitudinal beam 20 and a rear longitudinal beam 22, on the other hand. Such as image 3 As shown, each panel or stringer includes a skin 24 reinforced by stiffeners 26 secured to at least one face of the skin 24 . Typically, stiffeners 26 are provided on the inner surface of the skin. [0004] For the rest of this description, the inner surface or face corresponds to the surface or face towards the inside of the center wing box. In contrast, the outer surface or...
