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.

Abstract: A gas lift valve assembly includes a housing, a check valve, and a fluid flow barrier. The housing defines an inlet port, an outlet port, and a main flow passage providing fluid communication between the inlet port and the outlet port. The main flow passage has an upstream end and a downstream end. The check valve includes a sealing element disposed at the downstream end of the main flow passage, and a valve member configured to sealingly engage the sealing element. The valve member is movable between an open position in which fluid flow is permitted in a downstream direction, and a closed position in which the valve member inhibits fluid flow in an upstream direction. The fluid flow barrier is disposed within the main flow passage, and is configured to direct fluid flow away from the sealing element when the valve member is in the open position.

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.

The arm member is generally parallel to a longitudinal axis of the tower structure. The additive printing device also includes a plurality of robotic arms secured to the arm member of the central frame structure. Each of the robotic arms includes a printer head for additively printing one or more materials. The additive printing device further includes at least one nozzle configured for dispensing a cementitious material. Moreover, the system includes one or more molds additively printed via the additive printing device of a polymer material. As such, the mold(s) define inner and outer wall limits of the tower structure. After the mold(s) are printed and solidified, at least one of the printer heads or the nozzle of the additive printing device is configured to dispense the cementitious material between the inner and outer wall limits of 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: The present application presents novel systems and methods for tracking reinforcement member placement in an additively manufactured structure that are simple, accurate, non-labor-intensive, and cost-effective. The present application also presents a novel method of manufacturing a tower structure comprising: depositing, via an additive printing system, a first printed layer of a wall with a printhead assembly, the wall at least partially circumscribing a vertical axis of the tower structure; positioning a first reinforcement member on the first printed layer; depositing, via the additive printing system, a second printed layer of the wall with the printhead assembly on the first reinforcement member, the second printed layer configured to hold a second reinforcement member thereon; and determining, via an optical sensor of the additive printing system, a position for placing the second reinforcement member based on the first reinforcement member positioning.
