A wing arrangement of an aircraft has a wing and at least one pylon for suspending an engine below the wing. The wing has a leading edge with a high-lift device, which is able to move between a deployed position in which the high-lift device projects forward of the leading edge, and which is interrupted in a forward intermediate region of the wing located at the leading edge, the pylon having a forward edge extending forward of the leading edge of the wing between a forward upper portion connected to the wing in the forward intermediate region and a forward lower portion connected to a nacelle of the engine. An element of narrow elongate shape protrudes longitudinally from the forward edge and, during flight at a high angle of attack of the aircraft, generates a vortex of aerodynamic flow that is propagated toward the forward intermediate region above the wing.

An aircraft wing arrangement including a wing and at least one strut for attaching the aircraft engine suspended under the wing and including a front zone situated projecting towards the front with respect to a leading edge of the wing. The front zone includes a lateral projection delimiting a lateral air flow channel while being projected towards a proximal end of the wing.
