Abstract

The invention relates to a wing box (1) of an aircraft (2) with a stiffened shell structure (3), consisting of fiber reinforced material comprising a skin (4) for absorbing shear loads, and several stringers (5) arranged on the inner side of the wing box (1) for absorbing axial loads, in which at least 60% of the mass of the stiffened shell structure (3) is concentrated in the stringers (5), wherein the stringers (5) provide at least 80% of the axial stiffness of the stiffened shell structure (3). In the specific case of wing structure, this embodiment allows the use of unbalanced laminates for the skin (4) to induce higher nose-down twist of the wing box (1) without any loss in bending stiffness and so envisaging higher weight saving capability.
