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 method for recycling a used rotor blade of a wind turbine includes processing the used rotor blade into a plurality of material fragments. The method also includes treating the plurality of material fragments to remove at least a portion of the at least one composite material and expose the at least one fiber material of the used rotor blade. Further, the method includes mixing the treated plurality of material fragments with, at least, an alkali activator to form a usable geopolymer concrete.

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.
