Abstract

Various technologies described herein pertain to a vertical axis wind turbine blade configured to rotate about a rotation axis. The vertical axis wind turbine blade includes at least an attachment segment, a rear swept segment, and optionally, a forward swept segment. The attachment segment is contiguous with the forward swept segment, and the forward swept segment is contiguous with the rear swept segment. The attachment segment includes a first portion of a centroid axis, the forward swept segment includes a second portion of the centroid axis, and the rear swept segment includes a third portion of the centroid axis. The second portion of the centroid axis is angularly displaced ahead of the first portion of the centroid axis and the third portion of the centroid axis is angularly displaced behind the first portion of the centroid axis in the direction of rotation about the rotation axis.

Dual-axis resonance testing of wind turbine blades

Patent Hughes, Scott; Musial, Walter; White, Darris

An apparatus (100) for fatigue testing test articles (104) including wind turbine blades. The apparatus (100) includes a test stand (110) that rigidly supports an end (106) of the test article (104). An actuator assembly (120) is attached to the test article (104) and is adapted for substantially concurrently imparting first and second forcing functions in first and second directions on the test article (104), with the first and second directions being perpendicular to a longitudinal axis. A controller (130) transmits first and second sets of displacement signals (160, 164) to the actuator assembly (120) at two resonant frequencies ofmore »« less

Vertical axis wind turbine airfoil

Patent Krivcov, Vladimir; Krivospitski, Vladimir; Maksimov, Vasili; ...

A vertical axis wind turbine airfoil is described. The wind turbine airfoil can include a leading edge, a trailing edge, an upper curved surface, a lower curved surface, and a centerline running between the upper surface and the lower surface and from the leading edge to the trailing edge. The airfoil can be configured so that the distance between the centerline and the upper surface is the same as the distance between the centerline and the lower surface at all points along the length of the airfoil. A plurality of such airfoils can be included in a vertical axis windmore »« less

Vertical axis wind turbines

Patent Krivcov, Vladimir [Miass, RU]; Krivospitski, Vladimir [Miass, RU]; Maksimov, Vasili [Miass, RU]; ...

A vertical axis wind turbine is described. The wind turbine can include a top ring, a middle ring and a lower ring, wherein a plurality of vertical airfoils are disposed between the rings. For example, three vertical airfoils can be attached between the upper ring and the middle ring. In addition, three more vertical airfoils can be attached between the lower ring and the middle ring. When wind contacts the vertically arranged airfoils the rings begin to spin. By connecting the rings to a center pole which spins an alternator, electricity can be generated from wind.

Methods and apparatus for twist bend coupled (TCB) wind turbine blades

Patent Moroz, Emilian Mieczyslaw; LeMieux, David Lawrence; Pierce, Kirk Gee

A method for controlling a wind turbine having twist bend coupled rotor blades on a rotor mechanically coupled to a generator includes determining a speed of a rotor blade tip of the wind turbine, measuring a current twist distribution and current blade loading, and adjusting a torque of a generator to change the speed of the rotor blade tip to thereby increase an energy capture power coefficient of the wind turbine.

Wind turbine blades, wind turbines, and wind farms having increased power output

Patent Kelley, Christopher Lee; Maniaci, David Charles; Resor, Brian R.

A wind turbine blade having a geometry that decreases the distance downstream at which freestream momentum is recovered is disclosed. The blade design increases the loading on the inboard portion of the blade and unloads the tip portion relative to a conventional blade designed to maximize power coefficient. A wind farm having a reduced inter-turbine distance and including one or more wind turbines having the new blade designs is also disclosed.
