Boundary layer (6) suction system for being adapted to a surface (1) exposed to the circulation of a fluid, the system comprising a portion of said surface (1) and:
- a bifurcation element (2) for bifurcating a mass of fluid flowing along the front face of the surface (1), comprising an aerofoil-shaped cross-section such that the fluid is bifurcated into a first and a second flow,
- a slot (3) located on the portion of the surface (1) and upstream the leading edge (5) of the bifurcation element (2), the slot (3) communicating the front and the rear faces of the portion of the surface (1),
- means for providing a pressure difference between the front and the rear faces of the surface (1) around the slot (3) such that a suction of the boundary layer (6) is performed through the slot (3) by said pressure difference. |
