Abstract
A rotor blade for a wind turbine is disclosed. The rotor blade may generally include a body formed at least partially from a core material. The body may generally define a pressure side and a suction side extending between a leading edge and a trailing edge. The rotor blade may also include a plurality of shear members and a plurality of stiffening members. The shear members may generally extend between the pressure and suction sides of the body and may each include a first end and a second end. The stiffening members may be spaced apart around the pressure and suction sides of the body, with each stiffening member being disposed at the first end or the second end of one of the shear members. Additionally, the rotor blade may include a skin extending around an outer perimeter of the body.
