摘要： A method of manipulating a boundary layer across a wind turbine rotor blade. The method includes coupling at least one vortex generator to the rotor blade. The vortex generator includes at least one sidewall that extends outwardly a radial distance from an outer surface of the rotor blade. The vortex generator is selectively positionable between a first position and a second position. A control system calculates a condition of the boundary layer. The vortex generator is positioned at one of the first position and the second position based on the calculated condition of the boundary layer for moving the vortex generator between the first position and the second position.

摘要： A blade for a vertical axis wind turbine and a lift type vertical axis wind turbine having the blade are provided to easily suppress excessive increase of the rotation rate of the wind turbine with a simple mechanical structure when increasing the rotation rate of the wind turbine to a prescribed value or more. The blade has an air brake and a shaft bearing disposed at a position nearer the rear edge with respect to the gravity center of the air brake. The air brake is mounted rotatably on the blade through the shaft bearing. Inside the front portion of the air brake, a substantially S-shaped spring backing plate is mounted. The spring backing plate largely protrudes frontward out of the air brake and urged by spring members serving as a protrusion forbidding member disposed nearer the front portion of the windsail chamber. When increasing the rotation rate over a prescribed value, the front edge of the air brake protrudes out of the wing surface by a centrifugal force while the rear edge of the air brake retracts inward from the wing surface, thus to produce air resistance, resulting in suppressing increase of the rotation rate of the wind turbine.

摘要： Wind turbine blade (10) including adjustable lift-regulating means (12, 13, 15, 17, 19, 21) arranged on or at the surface of the wind turbine blade (10), said lift-regulating means being provided with activating means by means of which they can be adjusted and thus alter the aerodynamic properties of the blade (10). The lift-regulating means (12, 13, 15, 17, 19, 21) and the activating means are adapted and arranged such that by activation of the activating means, the lift can be reduced in a zone extending in the longitudinal direction of the blade (10) from a first position adjacent the blade tip (14) to a second position between the position and the blade root (16) and this second position is variable in the longitudinal direction of the blade (10) by adjusting activate means. The lift-regulating means are formed of at least one flexible flap (12, 13, 15, 17, 19, 21). The invention further relates to a wind turbine rotor including such wind turbine blades, to a wind turbine and to a method of controlling the wind turbine.
