Patent ID: 8490286

Claim:
A method for manufacturing a part of a fuselage of an aircraft, the said part of a fuselage comprising at least two fuselage sections each made of composite material, the method comprising the successive steps of: performing a longitudinally cut in a first single-piece fuselage section made of composite material so as to form therein an edge on each side of the cut, the cut being made linearly through the entire thickness of the first single-piece fuselage section; spreading apart the edges; reassembling the first single-piece fuselage section and making a longitudinal joint, wherein the longitudinal joint is made by bringing the edges together and fastening them, a diameter of the first single-piece fuselage section after performing the cut being inferior to a diameter of the first single-piece fuselage section before performing the cut; and forming the said part of the fuselage by assembling the first single-piece fuselage with a second single-piece fuselage section made of composite material, the diameter of the first single-piece fuselage section after performing the cut being equal to a diameter of the second single-piece fuselage section.
