A wind turbine rotor having variable blade pitch is provided. According to one embodiment, the wind turbine rotor includes a hub defining a predetermined number of openings, the hub further including a rotatable adjustment layer defining a predetermined number of slots, wherein the slots corresponds to the openings; and one or more blades secured in the hub, each of the one or more blades including a blade root, and a protrusion extending from the blade root, and wherein the protrusion of each of the one or more blades is engaged by a corresponding slot of the adjustment layer, wherein rotation of the adjustment layer translates the protrusions of each of the one or more blades, thereby rotating each of the one or more blades about the longitudinal axis. The rotor may be removably secured to a generator shaft by a spring, allowing easy adjustment of the rotor for educational use. |
