STIFFENER FOR AN AIRCRAFT FUSELAGE, METHOD FOR MANUFACTURING SAME, AND AIRCRAFT FUSELAGE EQUIPPED WITH SUCH A STIFFENER

摘要

This stiffener is intended for a fuselage. It comprises a hollow section that can be trapezoidal, with a base attached to the fuselage or to the floor, high enough rising sides and a top side contributing to the rigidity and cohesion of the stiffener. A direct assembly with the fuselage is possible. The base is made of two edges provided one on the other or in front of the other. This rigid stiffener, in spite of its discontinuous section, can be manufactured by simple foldings of a planar metal sheet at the beginning.
