Abstract:
1. A method for manufacturing a structural element intended for aeronautical construction, comprising a web extending substantially in a plane L,H, L being the longitudinal direction and H being the transverse direction, the web having a length L 1 and a height H 1 , the structural element being intended to be subjected to bending stress by a moment perpendicular to the said plane L,H, and one or more adjacent stringer elements which are substantially perpendicular to the web and which extend in the transverse direction, comprising the following steps (i) at least a first and second metal block are made available, the limit of elasticity under compression of the first metal block being greater than that of the second metal block, (ii) the first metal block is machined in such a manner as to obtain a first machined monolithic part S which comprises a first web portion having a length L (iii) there is prepared, by shaping the second metal block, at least one second part T comprising at least a second web portion of length L (iv) the first monolithic part S and the second part T are assembled by placing the web portions end-to-end over their entire common length L
