Abstract
Vertical axis wind turbine and horizontal wind turbine each with a rotary airfoil assembly that has helical swept airfoils whose free ends each have a spoiler. The vertical axis wind turbine has permanent magnet discs for levitating static weight of an entirety of the rotary airfoil assembly via magnetic repulsion. There is a hub or affixing the permanent magnet discs within a frame structure in a manner that counteracts both a coefficient of friction (“COF”) associated with rotation of the rotary airfoil assembly and ensuing bearing wear imparted from the rotary airfoil assembly. The horizontal axis wind turbine has collapsible telescoping towers.
Claims25
A wind turbine, comprising:
- a frame structure;
- a rotary airfoil assembly supported by said frame structure, said rotary airfoil assembly including helical swept airfoils that are asymmetric and that rotate to capture wind throughout a circumference of the rotary airfoil assembly from both windward and leeward sides;
- permanent magnet disc means for levitating static weight of an entirety of the rotary airfoil assembly via magnetic repulsion;
- hub means for affixing said permanent magnet disc means within said frame structure in a manner that counteracts both a coefficient of friction (“COF”) associated with rotation of the rotary airfoil assembly and ensuing bearing wear imparted from the rotary airfoil assembly;
- and
- electricity generating means for generating electricity in response to rotation of the helical swept airfoils.
A wind turbine electricity generator, comprising:
- a frame structure;
- a rotary airfoil assembly supported by said frame structure, said rotary airfoil assembly being arranged to rotate in response to wind forces;
- electricity generating means for generating electricity in response to rotation of the rotary airfoil assembly, said electricity generating means including at least one alternator on one of a plurality of driveshaft sections stacked one over the other in succession;
- an electronic control module (ECM) responsive to sensed inputs for issuing commands;
- and
- a multi-speed transmission responsive to said commands for varying a speed of rotation of said driveshaft sections of a main shaft accordingly under hydraulic speed control, the multi-speed transmission also including means for providing the hydraulic speed control via regulation of flow from a hydraulic pump, said hydraulic speed control providing protection in response to further ones of the commands against reaching wind gust generated over-speed conditions that arise from excessive rotation of the rotary airfoil assembly by lowering a rotational speed of or stopping rotation of said driveshaft sections.
