FIELD: transport.
SUBSTANCE: invention relates to structural elements of wings, particularly, to aircraft wing torsion box made of composites. Wing torsion box comprises top and bottom stringer panels. Front and rear spars and ribs of said panels divide torsion box inner space into compartments. Stringers are arranged in panel from the skin outer side and feature cross-section with the outrigger flange and set at spacing approximating to flange width. Stringers outer surfaces are coated with a thin layer of composite to make the panel outer skin. Stringer walls can plastically deform at impact loads.
EFFECT: higher safety of panels, simplified design and repair.
