Abstract

In order to be able to reduce the time and cost required for final assembly of an aircraft, a junction rib (37) designed for the wing-central wingbox junction comprises a main web (39) and an upper flange (16A) and a lower flange (16B) which extend from the main web, on a first side (C1), wherein the main web has a junction surface (24) arranged on a second side (C2) opposite the first side; the main web includes rows of orifices (34) opening on the second side in the junction surface and on the first side; the orifices (34) comprise a first row of orifices (R1) and a third row of orifices (R3) formed in an upper part of the main web on either side of the upper flange, and a second row of orifices (R2) formed in a lower portion of the main web; and each one of the rows of orifices (34) comprises orifices in a free state.

Description

technical field [0001] The present invention relates to the field of aircraft construction, and more particularly to joint ribs designed for wing-central wing box joints of aircraft, methods for manufacturing such joint ribs, the use of such joint ribs or the method as an Use as part of a method for manufacturing a central wing module of an aircraft, use of a method for manufacturing a central wing module of an aircraft as part of a method for manufacturing a fuselage section of an aircraft, and finally for the manufacture of an aircraft Use of a method of fuselage section as part of a method of manufacturing an aircraft. Background technique [0002] In an aircraft that includes a fuselage and wings—the wings consist of two opposing symmetrical wings fastened to the fuselage—the fuselage typically includes a box-shaped structure known as a "central wing box," described in " Fastened to the "central wing box" are corresponding structures with wings that are also formed as b...
