Abstract: In one aspect, a rotor blade for a wind turbine includes a body extending between a root end and a tip end. The body may include a root portion extending from the root end. The root portion may include an inner surface defining an inner circumference. In addition, the rotor blade may include a root stiffener disposed at least partially within the root portion of the body. The root stiffener may include a plurality of arms extending radially from the inner surface and may be configured to extend circumferentially around only a portion of the inner circumference of the root portion.

Abstract: A rotor blade for a wind turbine includes an internal support structure including a plurality of fixed, spaced support members extending in a chord-wise and span-wise direction and defining a generally aerodynamic contour of the rotor blade. A plurality of the support members have an outer surface with a longitudinally extending slot defined therein. A plurality of fabric strips are attached over the internal support structure in a tensioned state and define an aerodynamic outer skin. The fabric strips extend over and are attached to the support members with a longitudinally extending insert member that presses the fabric strips into the slot and lockingly engages within the slot.
