| 摘要 |
The invention relates to an aerodynamic wind propulsion device, particularly for watercraft, comprising an aerodynamic wing being connected to a steering unit located below the aerodynamic wing and coupled to the aerodynamic wing via a plurality of lines, particularly steering lines and/or fixing lines, a tractive cable, wherein a first end of the tractive cable is connected to the steering unit and a second end of the tractive cable is connected to a base platform, the aerodynamic wing having an aerodynamic profile which generates a lifting force in the direction of the traction cable when the air stream direction is about perpendicular to the tractive cable, a plurality of reefing lines located across the aerodynamic wing for increasing and decreasing the lifting force by changing the shape and/or dimension of the aerodynamic wing. According to a first aspect of the invention, such an aerodynamic wind propulsion device is provided, characterized by a guiding arrangement for guiding the reefing lines, wherein at least two of the reefing lines are guided by the guiding arrangement such that said at least two reefing lines can be controlled and/or activated, particularly hauled in and veered out, independently from each other, in particular during starting and landing manoeuvres.
