<p>There is provided a vent stringer which has improved lightning protection capability and by which a wing can be manufactured efficiently and accurately, and an aircraft main wing provided with the vent stringer. A vent stringer 20 is formed by a pair of ribs 21 rising in the direction perpendicular to an inner surface 11a of a wing panel 11, and a cover 22 provided in the tip end portions of the ribs 21. Since rivets 23 are not exposed to an outer surface 11b of the wing panel 11, a spark is prevented from occurring in a fuel tank 30, which is provided in a main wing 10, through the rivet 23 at the time of a lightning strike. Further, since the rib 21 is formed by being machined integrally with the wing panel 11, the rib 21 is formed with high accuracy so as to match the curved shape of the wing panel 11. On the other hand, the cover 22 has only to be formed by curving a strap member so as to match the shapes of the wing panel 11 and the ribs 21.</p> |
