Device comprising an asymmetrical adjustable wing profile

A device which comprises an asymmetrical wing profile and an adjusting device, which asymmetrical wing profile has a profile thickness and a profile chord extending between a wing leading edge and a wing trailing edge, which asymmetrical wing profile has, in at least one longitudinal portion, a three-part variable wing profile in which a front and a rear wing segment are joined to a central wing segment in an articulated manner by means of two hinges having axes of rotation and are designed to permit a rotational movement about the associated axis of rotation with respect to the central wing segment, which central wing segment forms an inherently rigid housing for receiving the adjusting device and has, as a longitudinal member of the asymmetrical wing profile, a hollow profile which forms an abutment for the adjusting device in at least one longitudinal portion, the adjusting device having at least one electric motor provided in the central wing segment and being designed to, with the aid of the at least one electric motor, enable a simultaneous rotating in or out of the front and rear wing segments with opposite directions of rotation to one another and thus a variable suction side of the asymmetrical wing profile, the angle of attack α of the profile chord changing when the front and rear wing segments are rotated in or out.
