Abstract: A rotor blade for a wind turbine includes an internal support structure including a plurality of fixed, spaced support members extending in a chord-wise and span-wise direction and defining a generally aerodynamic contour of the rotor blade. A plurality of the support members have an outer surface with a longitudinally extending slot defined therein. A plurality of fabric strips are attached over the internal support structure in a tensioned state and define an aerodynamic outer skin. The fabric strips extend over and are attached to the support members with a longitudinally extending insert member that presses the fabric strips into the slot and lockingly engages within the slot.

Abstract: A method for manufacturing a tower structure of a wind turbine includes printing, via an additive printing device, a plurality of concentric sections of the tower structure of the wind turbine. The concentric sections may be printed simultaneously from concrete, may include tensioning cables or other structural supports, and may define other support flanges or overhangs. After curing, the method may include raising an inner section of the plurality of concentric sections to a top of an adjacent outer section and joining the two sections. This process may be repeated to telescope the concentric sections and raise the tower structure.

Abstract: An additive printing device and a method for using the same to manufacture a tower structure of a wind turbine is provided. The additive printing device includes a vertical support structure, a support ring suspended from the vertical support structure, and a printer head movably coupled to the support ring for selectively depositing cementitious material. A drive mechanism, such as a rack and pinion, moves the printer head around the support ring while selectively depositing cementitious material. The vertical support structure may be raised and/or the relative position between the vertical support structure and the printer head may be adjusted to raise the printer head to print subsequent layers. This process may be repeated to print the tower structure layer-by-layer from the ground up.
