A flat-packable wind turbine assembly kit, includes a flat-packed bendable airfoil having an upper edge and a lower edge. The flat-packed bendable airfoil is capable of assuming a predefined curvature upon assembly. The flat-packed bendable airfoil includes upper connecting elements distributed along the upper edge and lower connecting elements distributed along the lower edge of the flat-packed bendable airfoil. The flat-packed bendable airfoil also includes a flat-packed upper plate including an upper mating orifices distributed in a contour corresponding to the predefined curvature. Further, the flat-packed bendable airfoil includes a flat-packed lower plate including lower mating orifices distributed in the contour corresponding to the predefined curvature. Thus, upon assembly when the upper connecting elements are connected to the upper mating orifices and when the lower connecting elements are connected to the lower mating orifices, the flat-packed bendable airfoil assumes the predefined curvature.
