摘要： In a method of manufacturing a blade shell half of a pre-bent wind turbine blade by means of vacuum-assisted resin transfer moulding (VARTM), a fibre lay-up (16) is placed on a mould surface (14) and a distribution layer (24) is placed above the fibre lay-up (16). At least one segmentation area is provided in the distribution layer by providing at least one transversely extending flow barrier in the distribution layer (24) preventing or restricting longitudinal resin flow to the distribution layer. A longitudinally extending first feed channel (27) is placed above the distribution layer (24). The first feed channel (27) is divided into at least two feed channel sections, a feed channel section being arranged in each distribution layer segment. A vacuum bag (43) is arranged on top of the mould part (13) to define a mould cavity. The mould cavity (44) is evacuated and liquid resin is supplied to each feed channel section through a resin inlet to fill the mould cavity and impregnate the fibre lay-up.

摘要： A method for performing a task in a tight place in an elongated profile, preferably in a wing blade with an outer shell for a wind power plant, whereby at least one barrier is formed transversely of at least one elongated channel in the profile and a balloon for use in performing the task. The method may include the following steps: establishing a number of inspection and mounting holes in the surface of the shell, mounting at least one inflatable balloons in the at least one channel, filling the balloon(s) with air, and applying at least one first material layer between the sidewalls of the elongated channel and across the balloon(s), the layer preferably being expanding polyurethane foam. The applied layer of material fills cracks and gaps between balloons and wing parts, providing a load-bearing layer between these parts. An additional layer may subsequently be laid upon the former layer.

摘要： A blade element (42; 44; 46; 48; 150; 250; 350) for mounting on a wind turbine blade (10) is provided. The blade (10) has a longitudinal direction (L) and a chord extending transversely to the longitudinal direction between a leading edge (18) and a trailing edge (20). The blade (10) has an airfoil profile with a thickness between a suction side and a pressure side along at least a part of the longitudinal direction (L) and with a position of maximum thickness between the leading edge (18) and the trailing edge (20). The blade element (10) has a shape so that, by mounting in a first longitudinal part of the wind turbine blade (10), it changes the profile of the first longitudinal part from a first airfoil profile (100; 200; 300) with an essentially pointed trailing edge (100; 200; 300) and a first chord length (c11; c21; c31) to a changed airfoil profile with a blunt trailing edge (153; 253; 353). The changed airfoil profile is a truncated profile of an imaginary airfoil profile (160; 260; 360) with an essentially pointed trailing edge and a second chord length (c12; c22; c32), which is larger than the first chord length (c11; c21; c31).

摘要： A blade for a rotor of a wind turbine has a substantially horizontal rotor shaft, the rotor including a hub, from which the blade extends substantially in a radial direction when mounted to the hub. The blade includes a profiled contour including a leading edge and a trailing edge as well as a pressure side and a suction side, the profiled contour when being impacted by an incident airflow generating a lift. The profiled contour is divided into a root region with a substantially circular profile closest to the hub, 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 profile of the root region to the lift generating profile of the airfoil region. The suction side comprises at least a first zone, which extends substantially in the direction of the incident airflow, and which is positioned in a zone of a cross-flow. The first zone includes a first barrier generating means adapted to generating a barrier of airflow, which extends essentially in the direction of the incident airflow, the barrier of airflow being of sufficient strength and length so as to effectively reduce the cross-flow.

摘要： A use of a core block for an impregnation process as well as a composite structure comprising such a core block is described. The core block has a first surface and a second surface, and a number of first grooves is formed in the first surface of the core. Furthermore, a number of second grooves is formed in the second surface of the core. The first grooves have a first height (h1) and a bottom, and the first grooves and the second grooves are part of a resin distribution network formed in the core block. The distance (t) between the bottom of the first grooves and the second surface of the core block is of such a size that the core block is flexible along the first grooves. Additionally, the sum of the first height and the second height is larger than the thickness of the core block, and at least one of the first grooves in the first surface of the core block crosses at least one of the second grooves in the second surface of the core block.

The invention also relates to a group of energy sources comprising a wind power plant and a number of remaining energy sources, where the power curve of the wind power plant is such that power supply is maximised in periods of time (203) when the total power output from the remaining sources of energy is low.

摘要： The present invention relates to a method of manufacturing a fibre-reinforced laminate (101), which laminate comprises at least one area on the surface of the laminate configured with projecting fibres 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 fibres (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 fibres to project from the surface of the laminate, said fibres 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.
