Abstract: A rotor blade for a wind turbine is disclosed. The rotor blade includes a blade root, a blade tip and a body extending between the blade root and the blade tip. The body has a pressure side and a suction side extending between a leading edge and a trailing edge. The body also defines an inner surface. The rotor blade also includes a spar member extending between a portion of the inner surface defined on the pressure side of the body and a portion of the inner surface defined on the suction side of the body. In addition, the rotor blade includes a plurality of structural members extending adjacent to the inner surface. The structural members are configured to intersect one another along the inner surface.
