Abstract:
An airfoil arrangement comprising:an airfoil; an engine including an engine nacelle; a pylon connecting said engine to said airfoil; a high lift leading edge flap movably connected to said airfoil so as to be extendable into an extended flap position and retractable into a retracted flap position relative to said airfoil, wherein an open space and a corresponding aerodynamic gap is formed between a leading edge portion of said airfoil, said pylon and a side edge of said leading edge flap facing said pylon, when said leading edge flap is in said extended flap position; and an auxiliary high lift device that is movably arranged so as to be extendable into an extended device position and retractable into a retracted device position, wherein said auxiliary high lift device in said extended device position is positioned in said open space to cooperate with said leading edge flap in said extended flap position and to at least partly close said aerodynamic gap, and wherein said auxiliary high lift device in said retracted device position is integrated into an outer contour of at least one of said nacelle and said pylon.
