Abstract

The invention relates to an aerodynamic wind propulsion device, particularly for watercrafts, comprising an aerodynamic wing being connected to a steering unit located below the aerodynamic wing via a plurality of tractive lines, a tractive cable, a first end of the tractive cable being connected to the steering unit and a second end of the tractive cable being connected to a base platform, the aerodynamic wing having an aerodynamic profile which generates an uplift force in the direction of the tractive cable when the airflow direction is about perpendicular to the tractive cable. According to the invention, an aerodynamic wing is provided being coupled to a steering unit located close below the wing via a plurality of tractive lines of different elasticity.
