Abstract: Methods of manufacturing a cementitious structure, such as a structure for supporting a wind turbine, include additively printing, via an additive printing device, one or more contours that include a cementitious material so as to form a cementitious structure in a layer by layer manner such that a first portion of the plurality of contours comprises a first plurality of contour coupling features that engage with a second plurality of contour coupling features of a second portion of the plurality of contours.

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 method for manufacturing a tower structure of a wind turbine includes additively printing at least a portion of a frame shape of the tower structure of the wind turbine of a first material on a foundation of the tower structure. Further, the first material has a first cure rate. The method also includes allowing the portion of the frame shape to at least partially solidify. The method includes providing a second material around and/or within the portion of the frame shape such that the portion of the frame shape provides support for the second material. The second material includes a cementitious material having a second cure rate that is slower than the first cure rate, with the different cure rates reducing the net printing time for the overall structure. Moreover, the method includes allowing the second material to at least partially solidify so as to form the tower structure.

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. During printing, the method includes embedding one or more reinforcement sensing elements at least partially within the cementitious material at one or more locations. Thus, the reinforcement sensing element(s) are configured for sensing structural health of the tower structure, sensing temperature of the cementitious material, heating to control cure time of the cementitious material, and/or reinforcing the cementitious material. In addition, the method includes curing the cementitious material so as to form the tower structure.

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: 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.
