Abstract: The present invention relates to a method of manufacturing a fiber-reinforced laminate (101), which laminate comprises at least one area on the surface of the laminate configured with projecting fibers for being joined to one or more other elements. This is accomplished by arrangement of a hybrid mat (505) most distally in the laminate which comprises at least two layers with fibers (105) transversally across the joining face (402) of the layers. The outermost layer (301) of the hybrid mat is removed prior to joining, whereas the innermost layer (506) of the hybrid mat remains a constituent of the laminate (101). The invention relates to different methods of causing fibers to project from the surface of the laminate, said fibers thus having a reinforcing effect on the joints. The invention also relates to a laminate manufactured by the disclosed methods and a blade for a wind power plant comprising such laminate.

Abstract: A wind turbine is operated with a blade in which a transition region is provided between a root region with a substantially circular or elliptical profile closest to a hub and an airfoil region with a lift generating profile furthest away from the hub. The transition region has a base part with an inherent non-ideal aerodynamic design so that a substantial longitudinal part of the base part without flow altering devices at a design point deviates from a target axial induction factor. A pitch of the blade and a rotational speed are adjusted to meet the target axial induction factor of the second longitudinal segment, and flow altering devices are provided so as to meet the target axial induction factor of the first longitudinal segment.

Abstract: A method of adjusting the speed of blades rotating in a rotor plane on a wind turbine, wherein the angle between at least two blades in the rotor plane is changed, whereby the tip speed of each individual blade can be optimised relative to the current speed of the wind experienced by the blade. Hereby it is possible to take into consideration the variation of the wind as a function of the height above ground level, and the yield of the wind turbine can be increased. The angular displacement of each blade can be changed individually independently of the remainder of the blades and cyclically. The method also comprises that each blade is accelerated on its way upwards in the rotation cycle and decelerated on its way down. Further details are provided about a system for controlling blades in a wind turbine comprising one or more wind speed meters, position meters, and/or acceleration meters, based on which parameters control of the angular displacement of each blade in the rotor plane is performed.
