STRUCTURAL ELEMENT AND METHOD OF MANUFACTURE

摘要

The invention relates to a method for manufacturing a structural element intended for aeronautical construction, typically a wing spar comprising a web and one or more adjacent stringer elements, 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 comprises a first web portion and at least one stringer element the second metal block comprises a second web portion placing the first and second web portions end-to-end over their entire common length. The invention permits the manufacture of bifunctional or multifunctional structural elements comprising several assembled parts but whose stringers have a mechanical strength greater than that obtained by traditional methods .
