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: The present disclosure is directed to a method for manufacturing a rotor blade component, such as shear web, of a rotor blade of a wind turbine. The method includes forming, via 3-D printing, an internal lattice structure of the rotor blade component. More specifically, the internal lattice structure includes a plurality of open cells. In addition, the method includes covering at least a portion of the internal lattice structure with an outer skin layer to form the rotor blade component.

Abstract: The present disclosure is directed to a rotor blade assembly for a wind turbine. The rotor blade assembly includes a rotor blade having a body shell with a pressure side, a suction side, a leading edge, and a trailing edge each extending between a root portion and a tip portion. Further, the rotor blade assembly includes a protection system configured to protect the rotor blade from ice accumulation or a lightning strike. The protection system includes at least one organic conductive element configured within the rotor blade. The protection system also includes a conductor source electrically or thermally coupled to the organic conductive element. Thus, the conductor source is configured to heat the organic conductive element so as to prevent ice from accumulating on the rotor blade or to provide a conductive path for the lightning strike.

Abstract: A rotor blade for a wind turbine 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 includes at least one shell member defining an airfoil surface. The rotor blade also includes one or more pin joints for connecting the first and second blade segments at the chord-wise joint. The pin joint(s) includes one or more pin joint tubes received within the pin joint slot(s). The pin joint slot(s) are secured within a bearing block. Further, a gap is defined between the pin joint slot(s) and the bearing block. Moreover, the rotor blade includes a shim within the gap between the pin joint slot(s) and the bearing block so as to retain the pin joint slot(s) within the bearing block. In addition, the shim is constructed of a liquid material that hardens after being poured into the gap.

Abstract: The present disclosure is directed to a method of manufacturing a rotor blade for a wind turbine. The method includes providing a blade mold of the rotor blade. Another step includes placing an outer skin layer in the blade mold. The method also includes placing one or more structural inserts in the blade mold atop the outer skin layer as a function of a load of the rotor blade. Further, each of the structural inserts includes a plurality of cells arranged in a predetermined pattern. Further, the cells have varying cell sizes. The method also includes placing an inner skin layer atop the one or more structural inserts and securing the outer skin layer, the one or more structural inserts, and the inner skin layer together to form the rotor blade.

Abstract: The present subject matter is directed to a wind turbine blade alignment method. A sensor provided on the blade at a blade station with a known twist angle is used to measure an installation angle of the blade station. The installation angle is adjusted if the installation angle measured by the sensor is not equal to the known twist angle. A wind turbine with such a sensor for measuring an installation angle used for blade alignment is also provided.
