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 system and method are provided for manufacturing a tower structure. Accordingly, an interlocking form ring is additively manufactured with a first printhead assembly. The interlocking form ring defines a plurality of recesses in a radially inner or a radially outer face. A cementitious material is deposited within one or more of the recesses with a second printhead assembly. At least one reinforcing member is positioned within the recess with the second printhead assembly. The second printhead assembly is positioned adjacent to the cementitious material during the curing thereof so as to provide a slip form for the curing of the cementitious material.

Abstract: A system for manufacturing a structure includes a supporting frame assembly moveable in a vertical direction of the structure. Further, the system includes an additive printing assembly secured to the supporting frame assembly. The additive printing assembly includes at least one printer head configured to dispense a first cementitious material. The system also includes a reinforcement dispensing assembly supported by the supporting frame assembly. Thus, the reinforcement dispensing assembly is configured to automatically and continuously dispense a plurality of reinforcing members as the structure is printed and built up via the at least one printer head and as the supporting frame assembly moves in the vertical direction.

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 reinforcement assembly for a tower of a wind turbine is disclosed as having at least one generally cylindrical tower section with an exterior wall and an interior wall defining a height and a thickness therebetween. At least one generally cylindrical tower flange is coupled to the tower section, the tower flange having at least one vertical flange portion and at least one horizontal flange portion. At least one adjustable generally cylindrical reinforcing member has, at least one vertical member portion with at least one flexible portion coupled to the exterior wall of the tower section, and at least one horizontal member portion adjustably engaged with at least one adjusting spacer. Adjustment of the adjusting spacer aligns the reinforcing member with an adjacent tower flange.

Abstract: The present disclosure is directed to an internal reinforcement assembly for a tower of a wind turbine. The reinforcement assembly includes a plurality of reinforcing rod members spaced circumferentially about the tower. Each of the plurality of reinforcing rod members includes a first end and a second end. The reinforcement assembly also includes an adjustable mounting component configured with each of the second ends of the plurality of reinforcing rod members. As such, the adjustable mounting components are mounted to an interior wall of the tower at a location to be reinforced. Thus, the reinforcing rod members interact with the tower to reinforce the tower at the location to be reinforced.

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.

Abstract: A system and method are provided for reducing vibrations and loads in one or more rotor blades on a rotor hub of a wind turbine when the rotor hub is in a locked or idling condition. A mass damper is attached at a fixed location on one or more of the rotor blades and is maintained on the rotor blades during the locked or idling condition of the rotor hub. The mass damper includes a movable mass component that is responsive to changes in the vibrations or oscillations induced in the rotor blades during the locked or idling condition of the rotor hub.
