Abstract: A wind turbine includes a hub rotatable about an axis and a blade coupled to the hub. The blade includes an inner blade portion having a first end and a second end. The inner blade portion is coupled to the hub at the first end and extends radially outward from the hub to the second end. The blade further includes an outer blade portion having a first end and a second end. The first end of the outer blade portion is pivotably coupled to the second end of the inner blade portion.

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 system for manufacturing a tower structure of a wind turbine includes an additive printing device having a central frame structure with a platform and an arm member. 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.
