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.

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 rotor blade includes a first blade segment and a second blade segment 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. The first blade segment includes a beam structure having a receiving end with at least one span-wise extending pin extending therefrom. The second blade segment includes a receiving section that receives the beam structure. The receiving section includes a chord-wise member having a pin joint slot defined therethrough. The pin joint slot receives the span-wise extending pin at the receiving end of the beam structure so as to secure the first and second blade segments together. Moreover, the chord-wise member, the pin joint slot, and/or the span-wise extending pin includes at least one compliant structure formed of a compliant material that allows a deformation thereof to follow a shear deformation of the rotor blade.

Abstract: A method for producing a hollow composite structure, such as a spar beam for a wind turbine blade, includes placing a membrane within a mold tool, the membrane being permeable to air and impermeable to resin. A mandrel is placed within the mold tool, the mandrel enclosed in an air tight layer that includes a vent. Fiber reinforcement material is placed around the mandrel within the mold tool and the membrane is sealed at least partly around the fiber reinforcement material and mandrel. The mold tool is closed with the vent line from the mandrel extending through the sealed membrane to outside of the mold tool. A vacuum is drawn in the mold tool while the mandrel is vented to outside of the mold tool, and while the vacuum is being drawn, resin is infused into the mold tool around the mandrel such that the resin is drawn towards the membrane.

Abstract: A wind turbine blade includes a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint. The first blade segment includes a beam structure extending lengthways that structurally connects with the second blade segment at a receiving section, wherein the beam structure forms a portion of an internal support structure and includes a shear web connected with a suction side spar cap and a pressure side spar cap. The present technology also includes a joint rod located at a first end of the beam structure for connecting with the receiving section of the second blade segment to form a coupling joint about a joint axis. The coupling joint is coupled to an adjustable elastic support. The receiving section may further include a torque coupling positioned offset from the joint axis, such that a bending motion of the beam structure automatically induces a twist motion. A method of assembling the wind turbine blade is additionally disclosed.
