An apparatus advantageously influences the wing root airflow along the wing root of an aircraft having a high lift system including leading edge slats provided on the main wings. The apparatus includes a respective vortex generator arranged on the inboard end of each leading edge slat in the area of the wing root, and further includes a respective transition fairing arranged on a separation edge that is let into the leading edge of the wing root and that borders along the inboard edge of the respective slat. The vortex generator is a rigid member fixed to the leading edge slat and may be in the shape of a horn, a disk, or a winglet. The transition fairing may be a rigid member fixed to the wing root along the separation edge, or may be a flexible elastic member that can be inflated to have a variable outer contour. The present system avoids the need of additional independently movable auxiliary flaps, and thus achieves a reduced weight, complexity, and maintenance requirement.

[ What is claimed is:] [1.] In an aircraft having a fuselage, a wing connected to said fuselage at a root area of said wing, and a leading edge slat movably arranged at a leading edge of said wing so as to be extendable to an extended position and retractable to a retracted position relative to said wing, an improved apparatus for influencing a wing root airflow over said wing at said root area, wherein said wing has a separation edge let into said leading edge adjacent said root area, an inboard edge of said slat borders along said separation edge when said slat is in said retracted position, and said improved apparatus comprises a vortex generator arranged on said slat at said inboard edge thereof and a transition fairing arranged on said wing at said separation edge so as to provide an aerodynamic transition from said separation edge toward said slat.
