Abstract: A rotor blade for a wind turbine includes first and second blade segments extending in opposite directions from a chord-wise joint. Each of the first and second blade segments has at least one shell member defining an airfoil surface and an internal support structure. The first blade segment includes a beam structure extending lengthwise that structurally connects with the second blade segment at a receiving section. At least one of the internal support structures of the first and second blade segments includes at least one spar cap. The rotor blade also includes one or more pin joints positioned on the spar cap(s) for connecting the blade segments. The spar cap is constructed of varying forms of materials along a span of the rotor blade, including at least two of: one or more infused composite laminates, one or more pre-preg composite laminates, one or more pre-fabricated or pre-cured composite elements, one or more additively-manufactured structures, or one or more non-composite structural solids.

Each of the first and second blade segments includes at least one shell member defining an airfoil surface and an internal support structure. The first blade segment includes a beam structure extending lengthwise that structurally connects with the second blade segment. Further, the beam structure forms a portion of the internal support structure of the first blade segment. Moreover, the beam structure is formed, at least in part, of a first portion constructed of a first composite material and a second portion constructed of a different, second composite material. Further, the first and second portions are connected together via a scarf joint. In addition, the scarf joint includes a different, third composite material arranged between the first and second composite materials.

Abstract: A method for retrofitting a wind turbine blade with a replacement blade tip segment includes producing a replacement blade tip segment with an internal beam receiver section, and producing a beam structure. The existing blade tip segment is cut away from the wind turbine blade, wherein the cut defines a chord-wise joint line at the remaining blade root segment of the wind turbine blade. The beam structure is fixed into spar structure of the blade root segment. The replacement blade tip segment is aligned and connected with the blade root segment in a span-wise direction so that the beam structure moves into the beam receiver section. A finish surface can be provided to the blade shell components of the blade root segment and the replacement tip segment at the joint line.

Abstract: A rotor blade component for a wind turbine includes a first structural component, such as a spar cap, formed from a plurality of stacked pultruded members. A second structural component, such as a shear web, is fixed to the first structural component at a joint interface. One or more webs form the joint interface, wherein each of the webs has a first section bonded between at least two of the pultruded members in the first structural component and a second section extending across the joint interface and bonded onto or into the second structural component.

Abstract: A wind blade includes a self-supporting structural framework, having a span-wise member, a plurality of chord-wise members, a fabric skin, and at least one of a stiffener and a mechanical element. The plurality of chord-wise members is coupled to the span-wise member and each chord-wise member and the span-wise member maintains an aerodynamic contour of the wind blade. Further, the fabric skin is disposed over the self-supporting structural framework. The stiffener and/or the mechanical element are coupled to the self-supporting structural framework, and are operable to provide a relative movement to the self-supporting structural framework for adjusting the aerodynamic contour and provide pretension to the fabric skin.

Abstract: A jointed rotor blade includes a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint. Each of blade segments has at least one shell member defining an airfoil surface and an internal support structure. The internal support structure of the first blade segment includes a beam structure extending lengthwise that structurally connects with the internal support structure of the second blade segment via a receiving section. The rotor blade further includes one or more pin joints positioned on at least one of internal support structures of the first blade segment or the second blade segment. Thus, at least one of internal support structures of the first blade segment or the second blade segment includes varying material combinations along a span of the rotor blade at locations of the one or more pin joints so as to reinforce the one or more pin joints.
