An aircraft wing including a mobile leading edge flap associated with a guiding device arranged at the front of a front spar of a wing box, and including: &#x2014;a pivoting member having one end connected to the spar by an articulated linkage; &#x2014;a pivoting member connected to one end of the member by an articulated linkage, the end of this member being connected to the flap via an articulated linkage; &#x2014;a guide rail receiving a tracking member supported by the member, the rail defining a path inscribed on the surface of an imaginary sphere, the centre of which corresponds to a point of convergence of the axes of the three linkages.

Aircraft wing comprising a mobile leading edge flap guided by a device located at the front of a wing box

An aircraft wing comprising a wing fixed central body, and a leading edge mobile slat () designed to be moved in rotation relative to the fixed central body along a circular trajectory inscribed on a sphere with center (C). According to the invention, the wing also comprises a cable carrier chain () comprising links () articulated to each other through articulation axes () that converge towards a single point, the chain being connected at its two ends to the fixed central body and to the mobile slat. Furthermore, the single point is the center (C) of the sphere, located on a rotation axis () of the leading edge mobile slat relative to the wing fixed body.
