Abstract
The invention relates to an aircraft wing including two members removably connected end to end by a coupling including: a male coupling part with spaced opposed upper and lower faces, a first face being planar while the second face has a longitudinal relief (9) with a V-shaped section, the first and second faces being mutually included towards each other at their free ends; a female coupling part with spaced upper and lower faces facing each other, a first face being planar while the second face has a longitudinal relief with a V-shaped section complementary to that of the relief, and the first and second faces being mutually inclined away from each other at their free ends; and a fastener for retaining the two parts coupled with their respective interacting faces in a mutual bearing relation.
Claims9
An aircraft wing having a longitudinal span and consisting of at least two wing elements positioned end to end, a first wing element being secured, dismantleably, to an adjacent second wing element using at least one coupling means,
- wherein said coupling means comprises:
- a male coupling piece borne by said first wing element substantially parallel to said longitudinal span of said wing, said male coupling piece having a mounting end for mounting on said wing element and a free end and exhibiting an upper face and a lower face which are separated from one another and face outward away from one another,
- a first of said faces being substantially planar,
- a second of said faces comprising a relief running longitudinally with a substantially V-shaped cross section, and
- said first and second faces being inclined with respect to one another so that said first and second faces converge toward one another toward said free end thereof;
- a female coupling piece borne by said second wing element substantially parallel to said longitudinal span of said wing, said female coupling piece having a mounting end for mounting on said second wing element and a free end and exhibiting an upper face and a lower face which are separated from one another and positioned facing one another,
- a first of said faces being substantially planar,
- a second of said faces comprising a relief running longitudinally with a substantially V-shaped cross section, of a shape that complements the shape of said V-shaped cross section of said relief of said second face of said male coupling piece, and
- said first and second faces being inclined with respect to one another so that said first and second faces diverge from one another toward said free end, with an inclination with respect to one another which is the complement of an inclination of said mutually-inclined faces of said male coupling piece, and
- retaining means capable of holding said two coupling pieces in a coupled position with said respective cooperating upper and lower faces thereof kept firmly pressed together,
- by virtue of which, when said two coupling pieces are in said coupled position said coupling pieces are immobilized relative to one another against any relative rotation.
