摘要： A passive magnetic bearing employs eddy currents in a copper core between neodymium annular magnets to support the copper core and an associated rotating shaft. The copper core has an annular flange that is coaxial with a hollow cylinder. The hollow cylinder supports a rotating shaft. An annular iron core is coaxial with and surrounds the annular flange. Annular neodymium magnets surround the upper and lower portions of the hollow cylinder. In some embodiments a touch-down bearing is made up of an upper and a lower bearing race that are spaced away from the upper surface and lower surface of the annular flange. The core rotates over the bearing race(s) until sufficient magnetic flux is generated to support the copper core and hence the shaft. Once spinning, a magnetic field is generated in the copper core.

摘要： What is proposed is a rotor with adjustable vanes, comprising a rotary structure rotating about a main axis and comprising a set of vanes rotating about a series of vane axes parallel to the main axis and defined by said rotary structure, and a mechanism associated with each vane and configured to control the variations in inclination of the associated vane according to the angular position of the rotary structure, this mechanism comprising a first element (65) supporting a pin (64) and a second element which is eccentric with respect to the first and configured to channel the movements of the pin along an imposed path.
According to the invention, said path is imposed by the translational movements of a carriage (62) along one or more guides (61) provided on the second element.-

摘要： Methods, systems, and devices are disclosed for wind power generation. In one aspect, a wind power generator includes a support base; inductors positioned over the support base in a circular array; an annulus ring track fixed to the base support and providing a circular track around which the inductors are located; an annulus ring rotor placed on the annulus ring track and engaged to rollers in the circular track so that the annulus ring rotor can rotate relative to the an annulus ring track, in which the annulus ring rotor include separate magnets to move through the circular array of inductors to cause generation of electric currents; and a wind rotor assembly coupled to the annulus ring rotor and including wind-deflecting blades that rotate with the rotor and a hollow central interior for containing a wind vortex formed from deflecting wind by the blades to convert into the electric energy.

摘要： A high performance hybrid turbine is provided which has an impeller towards which a fluid flow of water, air, or other fluid is conveyed for rotation of the impeller around an axis of rotation. The impeller exploits the thrusts that the fluid flow exerts on the elements constituting the impeller and the thrusts generated by a certain number of airfoils provided inside the elements of the impeller. The high performance hybrid turbine, if used as a wind turbine, can operate at much higher wind speeds than conventional wind turbines.

摘要： Proposed is a wind turbine having a vertical axis rotor mounted in a fixed cylindrical housing provided with outwardly opening shutters. The rotor consists of a rotating core comprising core blades fastened between two circular bases and forming a Ugrinsky rotor, and an annular impeller configured for independent rotation about said core. The impeller comprises impeller blades fastened between two ring-shaped bases and forming a continuation of the core blades, wherein common inter-blade channels are formed which narrow toward the centre of the rotor. Also proposed are wind power stations based on the wind turbines described above, said turbines being mounted vertically one above the other to form a generating tower, or being mounted on a facade of a high-rise building. Technical result consists, in particular, in increasing the efficiency of the wind turbine and making it possible to incorporate wind power stations into an urban environment.

摘要： A flow turbine rotor whose operation is based on aerodynamic profiles with leading and trailing edges clearly defined by their construction, adapted for nominal operation at specific speed blade speed greater than 1.5 of the incoming wind speed, characterized in that the angle angle α, measured as a shift in the blade rotation axis (1) between the angular position of the blade trailing edge, from ¼ to ½ of the rotor height is at least 20 percent smaller than the angle β, measured as a shift in the blade rotation axis (1) between the angular position of the trailing edge of the blade, from ½ to ¾ of the height of the rotor.

摘要： The present disclosure is directed to towerless vertical-axis wind turbines with pre-tensioned rotors. The present disclosure is further directed to a vertical-axis wind turbine (VAWT) with supported blade ends (e.g., Darrieus type) which replaces the center tower with tensioned supports, such as tensioned guy wires, and blade pre-load.

摘要： An energy-producing system comprising an axle configured to be driven by an electric vehicle's wheels when in motion. The axle supports a series of wind-catching cups contained within an aerodynamic housing configured to direct air to the cups while also increasing the air speed. During vehicle motion, the cups are acted upon by rushing air causing the rotation of the axle such that the rotation may be transferred into energy via a generator/alternator linked thereto. A series of similarly polarized magnets integrated on said cups and/or spacers and/or housing proximate thereto further maintain the axle in motion during short vehicle stops. The system extends the life of the batteries between charges as well the distance the vehicle can travel between charges. A power controller is configured to distribute power from said generator to an axle drive motor, vehicle drive motor and/or start-up battery pack.

摘要： A span-wise extending pin for joining blade segments of a rotor blade includes a distal portion having a length defined by a first end and an opposing, second end. The distal portion has a conical shape extending for at least a portion of the length thereof for providing ease of insertion of the pin into a pin joint slot of one of the first and second blade segments. The pin also includes a pin portion adjacent to the distal portion. The pin portion includes a first section and a second section. The second section is configured for securing within a beam structure of the first blade segment. The first section extends span-wise from a receiving end of the beam structure. The pin also includes a proximal portion having at least a rod member that extends span-wise through and secures together the pin portion and the distal portion.
