STIFFENED MULTISPAR TORSION BOX

摘要

The invention relates to an integrated structure of a composite material multispar torsion box (1) for aircraft, comprising a lower skin (12), an upper skin (11), several spars (9) defining cells (14), the first cell (19) being the closest to the input of load in the box (1), said structure comprising unit elements in the first cell, which unit elements provide the torsion box (1) with the necessary torsional rigidity to prevent the deformations occurring as a result of local loads.
