Impact resistant and damage tolerant aircraft fuselage
First Claim
1. 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 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.

Abstract
Aircraft fuselage section (32) subjected to impacts of external bodies, the aircraft fuselage having a curved shape with at least a vertical symmetry plane (A-A) and a central longitudinal axis and comprising a skin (35) and a plurality of frames (37) arranged perpendicularly to said longitudinal axis (33), the aircraft fuselage section also comprising at least an inner reticular structure (51, 53) mounted on a supporting structure (41, 43) comprising longitudinal beams (39) attached to the skin (35) and interconnected with said frames (37), said inner reticular structure (51, 53) being arranged for creating at least one closed cell (75) with the skin (35) for improving its resistance and its damage tolerance to said impacts. Said inner reticular structure (51, 53) can be formed by panels (61), rods (65, 65′), cables (67, 67′) or belts (69, 69′).
