Boundary layer suction system

A boundary layer suction system configured for being adapted to a surface exposed to the circulation of a fluid, the system comprising:

• a portion of said surface having a front and a rear face,
• a bifurcation element configured for bifurcating a mass of fluid flowing along the front face of the surface, said bifurcation element comprising an airfoil-shaped cross-section such that the fluid is bifurcated into a first and a second flow, the first flow being movable between the bifurcation element and the surface,
• a slot having an opening in the portion of the surface, wherein the opening is located at the portion of the surface downstream of a leading edge of the bifurcation element, the slot providing communication between the front and the rear faces of the portion of the surface, and
• means for providing a pressure difference between the front and the rear faces of the surface around the slot such that a suction of the boundary layer is performed through the opening by said pressure difference,
• wherein a wall of the bifurcation element extends towards the front face of the surface exposed to the flow and terminates at a downstream portion of the opening of the slot whereby the flow of a mass of fluid is guided through the opening and into the slot.
