A spoiler and wing of an aircraft. A bottom surface of the spoiler has several longitudinal, elongated grooves. At least some of the grooves are equipped with one or more vortex generators. Further, the invention relates to a wing having in its back part at least one flap and having at least one spoiler of the invention arranged on the section between the wing and flap. The invention also relates to a method and control surface for generating vortexes.

Arrangement for generating vortexes

An arrangement for fastening stringers of an aircraft wing to a transverse wing rib in the wing. An elongated fastening element is arranged to the side of the wing rib comprising a plate-like flexible portion close to the wing rib, and the first longitudinal edge of the flexible portion is fastened to the side of the wing rib and the second free longitudinal edge comprises a stiffening portion. The ends of the stiffening portion also comprise fastening portions, from where the fastening element is fastened to the stringers. The flexible portion in the fastening element is formed to be flexible in the longitudinal direction of the wing rib, and by bending the flexible portion in the longitudinal direction of the wing rib the stiffening portion can if necessary be transferred during the assembly of the wing. The stiffening portion is in turn dimensioned to carry vertical loads.
