摘要： The present invention relates to a design concept by which the power, loads and/or stability of a wind turbine may be controlled by typically fast variation of the geometry of the blades using active geometry control (e.g. smart materials or by embedded mechanical actuators), or using passive geometry control (e.g. changes arising from loading and/or deformation of the blade) or by a combination of the two methods. The invention relates in particular to a wind turbine blade, a wind turbine and a method of controlling a wind turbine.

摘要： A deformable trailing edge section (3) of a wind turbine blade (1), at least part of said section (3) being formed in a deformable material. The blade section (3) comprises one or more cavities (5) being in connection with or connectable to a fluid source in a way that allows fluid to stream from the fluid source to the cavity or cavities (5), so that the shape of the deformable trailing edge section (3) and thereby the camber of the blade cross-section (3) is changeable by the pressure of fluid in the cavity or cavities (5) with insignificant changes of the thickness and chord wise length of the deformable trailing edge section. Furthermore a wind turbine blade (1) is described, having at least one of such trailing edge section (s) (3) and to a system (11) for mounting a blade section (3) on a main blade (2) of a wind turbine. In addition a method of manufacturing a deformable trailing edge section (3) of a wind turbine blade (1) is disclosed.

摘要： The present invention relates to a wind turbine with oscillation damping means provided at the nacelle and being designed for damping edgewise oscillations of the rotor blades in the rotational plane of the rotor. In particular, the invention relates to a wind turbine in which the oscillation damping means are provided at the end of the nacelle being opposite to the end from which the rotor extends and are designed for damping oscillations of the first eigenfrequency of the rotor blades in the rotational plane, especially oscillations being perpendicular to the rotational axis of the rotor. The damping means are advantageously designed to dampen oscillations of a frequency being substantially equal to the first eigenfrequency in the rotational plane of the at least one blade minus the frequency of rotation of the rotor. The oscillation damping means of the present invention are preferably capable of damping oscillations being substantially horizontal and substantially perpendicular to the rotation axis.

摘要： The present invention relates to a hub assembly of a rotor for holding at least one wing, wherein the at least one wing is connected/mounted to the hub assembly in at least two suspension points. The hub assembly may be applied to any kind of either energy extracting devices such as wind turbines or the like or lift producing devices such as helicopter rotors or propellers. The invention is suited for rotors in general and is able to enable coning movement of wings connected/mounted to the hub assembly, enable teetering movement of the rotor and enable alteration of the pitch angle of the wings connected/mounted to the hub assembly. The hub assembly according to the present invention provides a hub where the pitching of the wings can occur synchronously/simultaneously due to an interconnection of the wings attached/mounted to the hub assembly and where coning of the wings may be applied at the same time with pitching of the wings and teetering of the rotor.
