摘要： A yaw control device includes a bottom horizontal plate, a top horizontal plate, a first vertical plate, and a second vertical plate. An aperture is positioned between first and second edges of the bottom horizontal plate, and is closer to a third edge of the bottom horizontal plate than to a fourth edge of that plate. A bottom edge of the first vertical plate is attached to a first edge of the bottom horizontal plate. An upper edge of the first vertical plate is attached to a first edge of the top horizontal plate. A bottom edge of the second vertical plate is attached to a second edge of the bottom horizontal plate. An upper edge of the second vertical plate is attached to a second edge of the top horizontal plate. The third edges of the horizontal plates are adapted to rotate about a shaft inserted through the aperture.

摘要： A yaw control device for a wind turbine, including: a vertical shaft; and, a vertical wing having a leading edge, a trailing edge, a first wing surface and a second wing surface, wherein the first wing surface extends between a first edge of the leading edge to a first edge of the trailing edge and wherein the second wing surface extends between a second edge of the leading edge to a second edge of the trailing edge; wherein the vertical wing is configured to receive the vertical shaft, and wherein the vertical shaft is biased toward the leading edge of the vertical wing; and wherein the vertical wing rotates about a longitudinal axis of vertical shaft and is configured such that the leading edge faces in the direction of an approaching wing.
