Abstract: A method for manufacturing a tower structure of a wind turbine includes printing, via an additive printing device, the tower structure of the wind turbine of a cementitious material. The method also includes printing, via the additive printing device, one or more additional airflow modifying features on an outer surface the tower structure of the wind turbine so as to reduce and/or prevent vortex shedding, excitation, and/or drag of the tower structure. Further, the method includes curing the cementitious material so as to form the tower structure.

Abstract: A system and method are provided for manufacturing a tower structure. Accordingly, one or more layers of a wall element are deposited with a printhead assembly. At least one recess is defined in the wall element. The recess(es) has a single, circumferential opening positioned along an inner reference curve or an outer reference curve of the wall element. The recess(es) also has a depth which extends in a radial direction and intersects a midline reference curve. A reinforcing element is placed entirely within the recess(es) at the midline reference curve.

Abstract: A method of manufacturing a tower structure includes providing an additive printing device having at least one printer head atop a support surface. The method also includes positioning a pre-fabricated component adjacent to the support surface. The pre-fabricated component is constructed of a composite material reinforced with a plurality of reinforcement members. Further, portions of the plurality of reinforcement members protrude from the composite material. Moreover, the method includes printing and depositing, via the at least one printer head, a cementitious material onto the support surface to build up the tower structure layer by layer around the pre-fabricated component. Thus, the portions of the plurality of reinforcement members that protrude from the composite material reinforce the cementitious material around the pre-fabricated component.

Abstract: A wind turbine system includes a wind turbine generator having a rotor and a nacelle mounted atop a tower structure. The tower structure is mounted to a foundation structure and includes a plurality of tower sections, each including one or more tower section flanges. The wind turbine system further includes one or more connector rings. Each of the one or more connector rings is disposed proximate two adjacent tower section flanges and includes a plurality of pad eye adaptors each having an opening formed therein. The wind turbine system further includes a plurality of tensioned cables, with each coupled to one of the pad eye adaptors at a first end and the foundation structure at a second end. The plurality of tensioned cables are coupled to the tower structure at different or multiple connector ring heights based on site conditions to yield the desired lateral stability.

Abstract: A method for manufacturing a tower structure, the method including printing and depositing, with at least one variable-width deposition nozzle of a printhead assembly, one or more layers of at least one wall element of the tower structure, the at least one wall element having an outer circumferential surface and an inner circumferential surface. The method also including forming, with the at least one variable-width deposition nozzle, at least one void into the at least one wall element. The method also including placing at least one reinforcement member within the at least one void so as to position the at least one reinforcement member closer to a neutral axis of the at least one wall element than at least one of the outer circumferential surface or the inner circumferential surface.

Abstract: A tower structure particularly suited for a wind turbine includes a lower tower section formed of concrete and an upper tower section formed of steel. A transition system connects the upper tower section to the lower tower section, the transition system including a concrete component having a tubular wall with a base portion fixed on the lower tower section and a head portion connected to the upper tower section. The head portion extends radially outward beyond the upper tower section. A plurality of first tensioning tendons extend longitudinally at least partially through the tubular wall and are anchored to the concrete component at a top face of the head portion at locations radially outward of the upper tower section.

Abstract: A tower structure of a wind turbine includes a plurality of tower sections stacked atop each other in an end-to-end configuration along a vertical axis to form the tower structure of the wind turbine at a wind turbine site. Each of the tower sections is formed of at least one first tubular portion and at least one second tubular portion. Further, the first and second tubular portions of each of the plurality of tower sections are concentric with each other. Moreover, the first tubular portion is formed at least in part, of a cementitious material and the second tubular portion is formed of a perforated material having a plurality of holes.

Abstract: A method for manufacturing a tower structure of a wind turbine at a wind turbine site. The method includes determining an optimized shape of the tower structure based on one or more site parameters. Further, the optimized shape of the tower structure is non-symmetrical. In a further step, the method include printing, via an additive printing device, the optimized shape of the tower structure of the wind turbine at the wind turbine site, at least in part, of a cementitious material. In addition, the method includes allowing the cementitious material to cure so as to form the tower structure of the wind turbine.
