摘要： The present invention relates to a blade (202) for a wind power plant (201) comprising a controllable actuator and at least one joint (206) transversally of the longitudinal direction of the blade, about which joint the outermost part (205) of the turning of the blade at an angle out of the original face of rotation of the blade can be controlled by the actuator. Hereby the rotor area can be controlled continuously during operation, and the distance between the blade tip and the tower can be increased/reduced. The turning and the bracing of the joint is controlled by means of wire pulls and/or actuators, such as eg electric, pneumatic or hydraulic pistons. The invention also relates to a method of improving the operation of a wind power plant in operation, using the same mechanism.

摘要： A wind turbine (100) includes a rotor assembly (104) having at least one blade (106) with a blade body (130) defining a leading edge (132) and a trailing edge (134) and adapted for movement in response to a wind flow over the body to produce electricity. A rigid acoustic flap (136) extends outward from the trailing edge, and a distal end (140) of the acoustic flap is substantially smooth and continuous. The flap reduces acoustic noise generated by the blade in use.

摘要： A method of transporting and storing a wind turbine blade (1) including a blade root (10) and a blade tip (4), where the wind turbine blade curves in the unloaded state in such a manner that the blade (1) presents a substantially concave face (30) and a substantially convex face (12), and such that said blade tip (4) is spaced apart from the longitudinal central axis (28) of said blade root (10). By the method, the wind turbine blade (1) is prestressed by means (2, 5, 6, 9, 13, 16, 17, 21, 22, 23, 24, 25, 26, 33) at a distance from the blade root (10) in such a manner that the blade tip (4) is brought closer to the longitudinal central axis (28) of the blade root (10). The invention also relates to a curved wind turbine blade (1) being provided with inner ballast tanks (21) at a distance from the blade root (10), whereby the blade is prestressed by filling said ballast tanks in such a manner that the blade tip (4) may be brought closer to the longitudinal central axis (28) of the blade root (10). The invention further relates to an apparatus including prestressing means for loading a curved blade at a distance from the blade root (10) in such a manner that the blade tip (4) is brought closer to the longitudinal central axis (28) of the blade root (10).

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 first position and the blade root (16) and this second position is variable in the longitudinal direction of the blade (10) by adjusting the 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.
