    摘要： The present invention provides a prime mover (2) for harnessing energy from a flow of fluid, the prime mover (2) comprising a shaft (4) having a rotational axis, arranged to be rotatably mounted to a substructure, the shaft (4) comprising at leas one arm (6) extending radially from the shaft (4), the or each arm (6) comprising at least one blade (8) wherein the or each blade (8) is oriented such that flow action on the blade (8) effects rotation of the shaft (4), characterized in that the or each blade (8) is movably mounted on an arm (6) and wherein each blade (8) is movable from a first position, having a first drag, to a second position, having a second drag, wherein the first drag is higher than the second drag. The prime mover (2) of the invention provides substantially reduced drag in a flow of fluid, and an increased torque output, compared to prior art prime movers.

    摘要： An airfoil for a wind turbine apparatus includes an airfoil body having an arcuate shape extending between a first end and a second end and an airfoil support secured to a midpoint on the airfoil body and connected to the outer end of the support arm. The airfoil body includes a first portion adjacent to the first end and a second portion adjacent to the second end. The first end and the second end are secured to the support arm, and the body of the airfoil is comprised of material capable of flexing in response to wind pressure. The first and second portions of the airfoil body extend away from each other in an extended position and collapse together in a collapsed position, and the orientation of the airfoil relative to the direction of the wind causes the airfoil to move between the open and closed positions.

    摘要： A wind turbine system includes a shaft, a rotor for driving the shaft, and a first fluidic teeter control assembly. The rotor includes a first blade engaged to the shaft by a hub, and has a degree of freedom to pivot relative to the shaft. A first teeter angle is defined between an instantaneous position of the first blade and a time-averaged plane of rotation of the first blade. The first fluidic teeter control assembly is engaged between the rotor and the shaft for providing a first dynamic teeter restraining force as a function of the first teeter angle and a fluidic resistance. The first dynamic restraining force is relatively low when the first teeter angle is within a first teeter operation range, and the first dynamic restraining force is higher when the first teeter angle is outside that range.
