A rotor yoke includes a blade attachment portion, a mast attachment portion, and an intermediate portion extending between the blade attachment portion and the mast attachment portion. The intermediate portion, the blade attachment portion, and the mast attachment portion define an optional inner edge, such that the inner edge, if present, defines an opening. The rotor yoke further includes a peripheral, outer edge extending about the blade attachment portion, the intermediate portion, and the mast attachment portion. At least one of the outer edge and the inner edge, if present, includes a reduced thickness portion exhibiting a thickness that is less than a thickness of an adjacent portion of the rotor yoke. ©KIPO&WIPO 2009
