Abstract

An aerodynamic profile has an adjustable flap, which has a forward profile area as well as a rearward profile area situated in the downward current, bounded by a pressure-side covering skin as well as a suction-side covering skin. The pressure-side and suction-side covering skins converge in the rearward profile area at a trailing profile edge. In the rearward profile area on the underside of the pressure-side covering skin, a flap is swivellably disposed such that, in the inoperative condition, the flap, pointing in the flow direction, rests against the contour of the pressure-side covering skin and, in the deflected condition, the flap encloses an angle with the pressure-side covering skin. An airtight hinge connection is integrated in the flap so that, on the side of the flap protected from the wind, a turbulence system which improves the flow conditions is formed.
