Abstract: A blade for a rotor of a wind turbine has a root region with a substantially circular or elliptical profile closest to the hub and an airfoil region with a lift generating profile furthest away from the hub. A transition region has a base part with an inner dimension that varies linearly in the radial direction of the blade in such a way that an induction factor of the first base part without flow altering devices at a rotor design point deviates from a target induction factor. The first longitudinal segment is provided with a number of first flow altering devices arranged so as to adjust the aerodynamic properties of the first longitudinal segment to substantially meet the target induction factor at the design point.

Abstract: A blade for a rotor of a wind turbine having a substantially horizontal rotor shaft, the rotor comprising a hub, from which the blade extends substantially in a radial direction when mounted to the hub. The blade comprises a main blade part having a profiled contour comprising a pressure side and a suction side as well as a leading edge and a trailing edge with a chord extending between the leading edge and the trailing edge. The profiled contour generates a lift when being impacted by an incident airflow. The profiled contour is divided in the radial direction into a root region with a substantially circular or elliptical profile closest to the hub, the substantially circular or elliptical profile having a diameter, an airfoil region with a lift generating profile furthest away from the hub, and a transition region between the root region and the airfoil region. The profile of the transition region gradually changes in the radial direction from the circular or elliptical profile of the root region to the lift generating profile of the airfoil region. The blade further comprises a first auxiliary airfoil having a first pressure side and a first suction side as well as a first chord extending between a first leading edge and a first trailing edge. The first chord has a length that is 75% or less of the diameter of the substantially circular or elliptical profile in the root region and the first auxiliary airfoil is arranged so that it extends in the radial direction along at least a part of the root region of the main blade part with a distance there between.

Abstract: The present invention concerns a method of producing a lightning diverter for conducting a lightning-induced electrical current, which is to be placed on structures such as wings on wind turbines, aircraft components, radomes and the like with the purpose of lightning protection. The method comprises the steps of making a plurality of holes in a plate of an electrically conductive material, filling said holes at least partly with one or more electrically non-conductive materials, and then finally dividing the plate—preferably into strips. The lightning diverter obtained hereby consists of a layer of electrically non-conductive material with a plurality of isolated segments of electrically conductive material.The invention further relates to a diverter strip with isolated segments of concave shapes being advantageous because of the good connection between the segments and the non-conductive material.

Abstract: The invention relates to a method of lightning-proofing a blade (1) on a wind-energy plant, which blade comprises a blade shell (2) configured essentially as a fiber-reinforced laminate, which laminate comprises electrically conductive fibers, wherein the blade comprises at least one lightning arrester (9) configured for conducting lightning current, including preferably to ground. The method comprises that the electrically conductive fibers are connected to each other, and that at least one metallic receptor (4, 24, 25) is arranged for capturing lightning current at or in proximity of the external face of the blade; and that the receptor and the fibers are connected to the lightning arrester for equalizing the difference in potential between the lightning arrester and the electrically conductive fibers. When the electrically conductive fibers are connected to each other, the fibers will cooperate on the conduction of a possible lightning current to prevent the current from running in individual fibers. Simultaneously the metallic receptor will serve as the primary lightning capturing device and reduce the risk of lightning striking the laminate. The receptor being connected to the lightning arrester, the current will predominately be conducted to ground, while the risk of transfer to the laminate is minimized in that a possible difference in potential between fibers and lightning arrester has been equalized.
