The inner anchor assembly may further include a disc-shaped plate and a plurality of inner anchor members to which the cables may be coupled. The inner anchor members may include a rear anchor portion and fore anchor portion, and these anchor portions may be angularly offset. A plurality of winglets and/or outer anchor members may be coupled to the outer ends of the fan blades to which the outer ends of the cables may be coupled.
