Abstract

A method for manufacturing a box-shaped structure for aircrafts, the structure extending along a longitudinal direction between a first longitudinal end and a second longitudinal end, and comprising: a first longitudinal wall; a second longitudinal wall facing the first wall and spaced from the first wall by a non-zero amount; a plurality of spars extending longitudinally and between said first wall and second wall; and at least one reinforcing rib arranged transversal to the spars at a transversal sector interposed between the first and the second longitudinal end; each spar has a spar cavity defining a lack of material extending longitudinally from an axial coordinate, which corresponds to the transversal sector, up to the second longitudinal end, so that the reinforcing rib can be easily inserted even after the integral coupling between the first wall, the second wall and the spars without compromising the structural properties of the box-shaped structure.
