Patent ID: 8117977

Claim:
An aerodynamic wind propulsion device, comprising an aerodynamic wing being connected to a steering unit located below the aerodynamic wing via a plurality of lines, a tractive cable, having a first end of the tractive cable connected to the steering unit and a second end of the tractive cable connected to a base platform, the aerodynamic wing having an aerodynamic profile which generates an uplift force in the direction of the traction cable when an airflow direction is about perpendicular to the tractive cable, a guiding line having a first end connected to the aerodynamic wing or to the steering unit, a pole being connected to the base platform, the pole serving as a docking point for the aerodynamic wing during starting and landing, characterized in that a second end of the guiding line is connected to the base platform during and between starting and landing maneuvers wherein the guiding line is guided through or along the pole and is capable of transferring a tensile force onto the aerodynamic wing at least during starting or landing.
