Wing comprising a leading edge slat and having means for preventing the transition to a turbulent boundary layer

A wing of an aircraft, said wing comprising:

• a fixed main part;
• a movable leading edge slat at a front of the main part between a retracted position, in which the leading edge slat is adjoined to the front of the main part, and a deployed position, in which the leading edge slat is lifted forwardly of the front of the main part,
• the leading edge slat having an upper surface rear edge, which, in the retracted position, is alongside an upper surface of the main part, and a lower surface rear edge, which, in the retracted position, is alongside a lower surface of the main part,
• the wing main part comprising an upper surface wall, which, in the retracted position of the leading edge slat, extends downstream and in alignment with the upper surface rear edge, and a lower surface wall, which, in the retracted position of the leading edge slat, extends downstream and in alignment with the lower surface rear edge,
• wherein the wing has, in the retracted position of the leading edge slat, an upper surface gap between an end of the upper surface rear edge of the leading edge slat and an end of the upper surface wall of the main part that are facing each other, and a lower surface gap between an end of the lower surface rear edge of the leading edge slat and an end of the lower surface wall of the main part that are facing each other,
• wherein the wing has an upper surface channel downstream of the upper surface gap and a lower surface channel downstream of the lower surface gap, and
• wherein the wing comprises a suction system connected to each channel and arranged to suck air contained in said channel, the suction system arranged inside the main part.
