Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a wind turbine blade de-icing system in which one or more actuators are used to apply a force to the blade interior to flex the blade surface into a curvature that can no longer support ice. While ice adheres quite easily to blade surfaces, it is brittle in comparison to the materials from which blades are typically made, and can be made to shear off from the blade surface if the surface flexes or distorts sufficiently. As blade surfaces are designed to flex a great deal before damage to the blade occurs, the ice can typically be dislodged without undue stress to the blade. Actuation can be achieved through a pressure source, or by mechanical actuators. Webs can be provided in the blade interior to increase the curvature of the surface as it flexes, and to divide the blade into regions that can then be independently controlled according to the propensity of ice to build up in those regions. Hinge lines in the blade surface or an ice-phobic surface can be used to increase the efficacy of the system.

Abstract translation: 本发明涉及一种风力涡轮机叶片除冰系统，其中一个或多个致动器用于向叶片内部施加力以将叶片表面弯曲成不再能够支撑冰的曲率。 虽然冰很容易粘附到叶片表面上，但是与通常制造叶片的材料相比，它是脆性的，并且如果表面充分弯曲或变形，则可以从叶片表面剪切掉。 由于叶片表面被设计成在对叶片的损坏发生之前很大程度地弯曲，因此冰通常可以被移除而不会对叶片产生不必要的压力。 致动可通过压力源或机械执行机构实现。 网可以设置在叶片内部，以增加表面弯曲时的曲率，并且将叶片分成若干区域，然后可根据冰在这些区域积聚的倾向独立地进行控制。 可以使用叶片表面上的铰链线或者是一个抗恐怖的表面来增加系统的功效。
