Device comprising an asymmetrical adjustable wing profile

A device comprising:

• 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 segments 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 an 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 of the profile chord changing when the front and rear wing segments are rotated in or out;
• wherein the device is designed as an aircraft with at least one wing, in which the adjusting device has a step detent gear mechanism and a retaining element, wherein in at least one longitudinal portion of the asymmetrical wing profile the central wing segment, with at least one electric motor and the front and rear wing segments of the three-part wing profile, are connected to the retaining element of the adjusting device in such a manner that the lift produced by the suction side of the variable wing profile can be adapted to the flight situation of the aircraft by actuating the adjusting device.
