  • a skin;

    a plurality of frames arranged perpendicularly to the central longitudinal axis;

    a supporting structure including a plurality of longitudinal beams attached to the skin and interconnected with the plurality of frames;

    an inner reticular structure mounted on the supporting structure offset from the skin towards the central longitudinal axis,wherein the inner reticular structure extends at least from a first longitudinal beam to a second longitudinal beam of the plurality of longitudinal beams and at least from a first frame to a second frame of the plurality of frames to form at least one closed cell with the skin that increases a resistance and damage tolerance of the fuselage section to an impact of an external body.
