| 摘要 |
The present invention relates to a method of manufacture of a stiffening transverse internal rib for an aerodynamic fairing of an engine mounting device, including: the production of a rib preform by superplastic forming having an outline of a broadly quadrilateral shape, and a central opening (52) traversing this preform; the division of the preform into two parallel straight-line segments (56, 60), which are diagonally opposed, causing the separation into two half-parts (46a′, 46a″) of the rib preform; and fishplating of the two rib preform half-parts (46a′, 46a″) by bolting.
