20110081247 | Wind Turbine Blade - A sectional blade for a wind turbine comprising a first and a second blade section extending in opposite directions from a blade joint, and each blade section comprising a spar section forming a structural member of the blade. The blade sections are structurally connected by a spar bridge over a spar joint, which comprises a center beam of two extending beam caps joined by one or more extending beam webs. The spar joint further comprises at least two extending spar caps and one or more extending spar webs connecting the spar caps to opposite sides of the center beam. A method of manufacturing such a sectional blade is also disclosed. | 04-07-2011 |
20110081248 | Wind Turbine Blade - A sectional blade for a wind turbine comprising a first and a second blade section extending in opposite directions from a blade joint, and each blade section comprising a spar section forming a structural member of the blade. The blade sections are structurally connected by a spar bridge extending into the first and second blade sections to facilitate joining of the blade sections. The spar bridge comprises a stiffening member protruding from the spar bridge in a chord wise direction of the blade for increasing the edgewise stiffness of the blade, and wherein a part of the surface of the stiffening member is shaped to follow an inner surface contour of the blade. A method of manufacturing such a sectional blade is also disclosed. | 04-07-2011 |
20110158788 | A SECTIONAL BLADE - The invention provides a sectional blade for a wind turbine. The blade comprises at least a first blade portion and a second blade portion extending in opposite directions from a joint. The first blade portion and the second blade portion are structurally connected by at least one spar bridge extending into both blade portions to facilitate joining of said blade portions. | 06-30-2011 |
20110293432 | SECTIONAL WIND TURBINE BLADE - Wind turbine blade comprising two or more blade sections each of which defines a non-joint zone and, at one or each of its ends, a joint zone. The blade sections are connected in pairs such that the joint zones of each pair are connected at a joint, whereby the joint is positioned between two non-joint zones. At least one of the joints have an increased thickness and a wider chord relative to the thickness and the chord of the two non-joint zone between which the joint is positioned so as to increase the second moment of inertia in the area of the joint. | 12-01-2011 |
20120308396 | SECTIONAL BLADE - A sectional blade for a wind turbine, the blade extending lengthwise between a tip and a root where the blade is attachable to a hub of a wind turbine, crosswise between a leading edge and a trailing edge, and thickness wise between a windward and a leeward outer surface. The sectional blade comprises a first blade portion and a second blade portion. The blade portions are formed as separate components and arranged to extend lengthwise in opposite directions from a junction where the blade portions join. The blade forms, in a cross section perpendicular to the lengthwise direction and through the junction, a maximum thickness location between the leading and trailing edges, the maximum thickness location being where the distance between the windward and leeward outer surfaces is larger than at any other location in this cross section. The sectional blade comprises an assembly board which is adhesively joined to an outer surface of both blade portions between the trailing edge and the maximum thickness location. | 12-06-2012 |

20100329865 | LIGHTNING PROTECTION MESH - A lightning protection mesh for a blade of a wind turbine comprising a first set of wires running in a first direction, and a second set of wires running in a second, different direction. The mesh has at least one tapered end at which wires from at least one of the first and second set of wires run together. The total conducting cross-sectional area formed by the wires in the tapered end is maintained within the tapered end, and the wires are bundled at the tapered end to provide an electrical connection to the mesh. | 12-30-2010 |
20120269643 | SECTIONAL WIND TURBINE BLADE - The invention relates to a sectional blade for a wind turbine, the blade comprising at least a first blade section and a second blade section extending in opposite directions from a blade joint, where each blade section comprises a spar section forming a structural member and extending in the longitudinal direction of the blade, and where the first and second blade sections are connected by fastening means restraining any movement of the first blade section relative to the second blade section length ways. The first and the second blade sections are structurally connected by a spar bridge protruding from one of the blade sections and terminating axially in an end portion, which is received in the spar section of the other blade section. The spar bridge and the spar section have interlocking shapes by which rotation of the spar bridge in the spar section is prevented thereby preventing rotation of one of the blade sections relative to the other. Further, the spar section of the other blade section comprises a receiving section extending from the blade joint and inwards into the spar section of that blade, which receiving section holds the spar bridge such that movement of the end portion of the spar bridge relative to the receiving section is enabled in the longitudinal direction. The invention further relates to a method of manufacturing a sectional blade as mentioned above. | 10-25-2012 |
