Abstract: The present disclosure is directed methods for manufacturing spar caps for wind turbine rotor blades. In certain embodiments, the method includes forming an outer frame or tray of the spar cap via at least one of three-dimensional (3D) pultrusion, thermoforming, or 3D printing. As such, the outer frame has a varying cross-section that corresponds to a varying cross-section of the rotor blade along a span thereof. The method also includes arranging a plurality of structural materials (e.g. layers of pultruded plates) within the pultruded outer frame of the spar cap and infusing the structural materials and the outer frame together via a resin material so as to form the spar cap. The resulting spar cap can then be easily incorporated into conventional rotor blade manufacturing processes and/or welded or bonded to an existing rotor blade.

Abstract: A rotor blade may generally include a shell forming an outer skin of the blade, with the shell defining a chordwise curvature. The rotor blade may also include a spar cap extending within the shell along a spanwise direction of the blade. The spar cap may be formed from an assembly of pre-cured laminate plates. In addition, the rotor blade may include an interior shelf positioned directly between the shell and the spar cap. The interior shelf may include an outer surface extending adjacent to the shell and an inner surface opposite the outer surface. The outer surface may define a curved profile generally corresponding to a portion of the chordwise curvature of the shell and the inner surface may define a planar surface along which the spar cap extends in a chordwise direction of the blade. The interior shelf may correspond to a pre-fabricated insert for the blade.

Abstract: The present subject matter is directed to a method for operating a wind turbine. The method includes calculating one or more blade root loads, e.g. a blade root resultant moment, of at least one rotor blade of the wind turbine. Another step includes estimating a span-wise loading of the rotor blade based at least partially on the one or more blade root loads. The method also includes determining a deformation margin of the rotor blade based at least partially on the span-wise loading and one or more estimated deformations occurring on the rotor blade. Another step includes controlling the wind turbine based on the deformation margin.
