For establishment of a laminar attachment line flow, the invention proposes an aircraft wing (10) comprising: a leading edge (12), the leading edge (12) including an attachment line (14),being a region where air impinging on the region flows in a boundary layer spanwise along the leading edge (12), a first slat (22) and a second slat (24),wherein the leading edge (12) and the attachment line (14) are at least partially formed at the first and second slats (22,24), the second slat (24) is located adjacent to the first slat (22) in the downstream direction of the attachment line flow, so that the leading edge (12) includes a slat-to-slat junction (26), and a slat cavity (30) is formed at the slat-to- slat junction (26) beneath a skin area (36) of at least one of the first and the second slats (22, 24), and a duct (38) having a duct entrance (40) at the slat-to-slat junction (26) for receiving spanwise flow along the leading edge (12) of the wing (10), the duct (38) beings at least partly formed by said slat cavity (30), wherein the duct entrance (40) extends around the leading edge (12) and over the range of positions of the attachment line (14) at the slat-to-slat junction (26). |
