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 w eb 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 tha t 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 .
