Abstract:
1. An aerodynamic profile comprising: a main profile body defining a profile depth direction and being shear-flexible in the profile depth direction, the main profile body having a trailing edge region; a tension-stiff and compression-stiff upper covering skin; a tension-stiff and compression-stiff lower covering skin, the upper and lower covering skins defining the main profile body; a bearingless and hingeless rear profile deformation region disposed at the trailing edge region; and at least one actuator disposed in the main profile body configured to initiate a flexural motion of the main profile body with a flexural deformation of the upper and lower covering skins resulting in a curvature of the upper and lower covering skins so as to deform the rear profile deformation region and to yield a flap deflection directed opposite to a direction of the flexural motion of the main profile body for an S-shaped deformation of the profile.
