Abstract:
1. An aerodynamic wind propulsion device, comprising: an aerodynamic wing ( a tractive cable ( the aerodynamic wing ( wherein at least two of said plurality of tractive lines have elastic behavior in a load range occurring in use of the aerodynamic wind propulsion device and the elastic behavior of said at least two tractive lines is different; and wherein at least one of said tractive lines has elastic properties which are different from other tractive lines to effect a deformation of the aerodynamic wing element in a first load condition to produce at least one of the following effects: said at least one tractive line having elastic properties which are different from the other tractive lines is coupled to a section of the aerodynamic wing to effect a deformation of said center section in the first load condition such that the aerodynamic profile in the first load condition has a cross section that is different from an ideal aerodynamic wing cross section.
