Aircraft wing arrangement comprising an engine attachment pylon defining, in the forward region, a lateral airflow channel

1. An aircraft wing arrangement comprising:

a wing comprising a distal end, a proximal end, at least one strut for attaching the aircraft engine suspended under the wing, and a front zone situated projecting towards the front with respect to a leading edge of the wing,

wherein the front zone of the attachment strut comprises a lateral projection delimiting a lateral air flow channel while being projected towards the proximal end of the wing, and

wherein the lateral projection includes a rear end surface in contact with the leading edge of the wing on a front end, the lateral projection being projected towards the proximal end of the wing over a projection length increasing going from its front end to its rear end.

2. A wing arrangement according to claim 1 , wherein the lateral projection includes, from its front end to its rear end, a free lateral edge rounded in shape.

3. A wing arrangement according to claim 1 wherein the attachment strut includes a first lateral flank oriented towards the proximal end of the wing, the first lateral flank including a concave-shaped portion participating at least partially in definition of the lateral projection.

4. A wing arrangement according to claim 1 , wherein the lateral projection is provided at a top part of the front zone of the attachment strut, so as to direct air flowing in the lateral air flow channel under the wing.

5. A wing arrangement according to claim 1 , wherein, in plan view, the lateral projection is present over at least 60% of the length of the front zone of the attachment strut, considered along a longitudinal axis of the strut passing through a front end point thereof.

6. A wing arrangement according to claim 1 , comprising two aircraft engine attachment struts, each of the struts including the lateral projection on its front zone.

7. An aircraft, comprising at least one wing arrangement according to claim 1 .
