Embodiment Construction
[0033] The outboard slat 20 is positioned adjacent to the wingtip extension 8 such that, after deployment, the end face 21 of the outboard slat 20 is in an upstream position affecting the airflow around or impinging on the wingtip extension 8 . Furthermore, due to the significant increase in the angle of attack of the wing 2 during take-off or landing phases, the flow characteristics over the unprotected wingtip extension 8 may be inhomogeneous and produce stall and flow separation phenomena, respectively.
[0034] In order to harmonize the local flow over the wingtip extension 8 and substantially avoid flow separation over the wingtip extension 8 , on the wingtip extension 8 and in regions located more inwardly adjacent to the wingtip extension 8 An arrangement of openings 22 is provided. These openings 22 are the central part of the local flow control device for influencing the local flow by sucking in air or blowing out air.
[0035] In order to increase aerodynamic lift a...
