Impact resistant and damage tolerant aircraft fuselage

A fuselage section having a curved shape with at least a vertical symmetry plane and a central longitudinal axis, the fuselage section comprising:

• 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 to form at least one closed cell with the skin,
• wherein the supporting structure is formed by at least two of the plurality of longitudinal beams and a set of transversal elements between the at least two of the plurality of longitudinal beams,
• wherein the supporting structure includes longitudinal elements interconnected with the set of transversal members, and
• wherein the supporting structure is configured to provide a planar polygonal supporting surface to the inner reticular structure.
