Abstract: An arrangement of aerodynamic auxiliary surfaces is configured for being arranged on the underside of an aircraft and furthermore includes a longitudinal axis and at least one aerodynamic auxiliary surface, wherein the aerodynamic auxiliary surface is laterally offset referred to the longitudinal axis, and wherein the aerodynamic auxiliary surface is configured for generating vortices when it is subjected to an oncoming air flow. This makes it possible to compensate vortices caused by the shape of the aircraft such that the directional stability of the aircraft can be improved and the aerodynamic drag may be reduced.

Abstract: A device for the generation of aerodynamic vortices to be arranged on the spanwise side edge of a wing, or a regulating flap adjustably arranged on the latter, which in each case have a chordwise direction and a spanwise direction, wherein the device is formed from one aerofoil component or from a plurality of aerofoil components, wherein the at least one aerofoil component is designed as a part that can be moved relative to the wing or regulating flap in its spanwise direction, wherein the device for vortex generation has an actuation device for the retraction and extension of the aerofoil components into a recess, and also a drive device to operate the actuation device. A regulating flap of a wing, and also a wing, with such a device for the generation of aerodynamic vortices, and a wing, which has at least two aerofoil segments at its side edge situated at the spanwise end.
