摘要： The present disclosure is directed to methods for manufacturing wind turbine rotor blades and components thereof, e.g. using 3D printing. In one embodiment, the method includes forming a rotor blade structure having a first surface and an opposing, second surface, the first and second surfaces being substantially flat. Another step includes printing a leading edge segment of the rotor blade onto the first surface, wherein heat from the printing bonds the leading edge segment to the first surface. The method also includes rotating the rotor blade structure having the leading edge segment attached thereto. A further step includes printing a trailing edge segment of the rotor blade onto the second surface, wherein heat from the printing bonds the trailing edge segment to the second surface. Another step includes securing one or more fiber-reinforced outer skins to the leading and trailing edge segments so as to complete the rotor blade.

摘要： A wind turbine including a support structure and one or more turbine blades is presented, that incorporates ways for reducing the radar cross section (RCS), wherein the support structure is notionally divided into an upper section in the shadow of the blade sweep area, and a lower section beneath the upper section, wherein the upper section is adapted to have the ways for reducing the RCS, and the lower section does not have the adaptation. The invention makes use of the realisation that the blade masking the tower as it rotates (or the blade being masked by the tower if facing away from a radar), contributes significantly to interference to radar systems, and so localised application of e.g. RAM can give good RCS reduction at a lower cost than treating the whole structure.

摘要： A wind turbine blade includes a multilayer composite structure including a first reflective layer, and a second layer including a plurality of resistive circuit analog (CA) elements. The CA elements are tuned so as to interact with the first layer to provide absorption of electromagnetic (EM) energy over a desired frequency range. The parameters of the CA elements can be varied to provide for frequency tuning and to maintain absorption at a specific frequency range despite varying layer separation, while at the same time ensuring that the mechanical properties of the CA layer are compatible with integration into the turbine blade.

摘要： A compressor includes a housing, and an anticorrosive coating covering a surface of the housing. The anticorrosive coating includes a base layer applied on the surface of the housing, and a surface layer applied on the base layer. Both the base layer and the surface layer are organic coatings. Thus, the housing of the compressor is effectively separated from the external environment by means of the two organic coatings, so as to ensure that the compressor is not corroded; moreover, the anticorrosive coating does not contain a metal coating, thereby preventing the problem of the compressor being severely corroded due to an exposed metal coating.

摘要： The present disclosure is directed to a rotor blade assembly for a wind turbine. The rotor blade assembly includes a rotor blade having surfaces defining a pressure side, a suction side, a leading edge, and a trailing edge extending between a blade tip and a blade root. Further, the rotor blade assembly includes a flexible extension having a first end and a second end. More specifically, the first end is mounted to a surface of the rotor blade and the second end is free. As such, during operation of the wind turbine, the flexible extension passively adjusts with a changing angle of attack of the rotor blade, thereby reducing variations in blade loading.

摘要： A component with a coating, wherein the component is a part of a wind turbine, the component is in contact with a lubricant and the lubricant comprises atomic hydrogen, is provided. The coating at least partly covers a surface of the component. The coating reduces diffusion of the atomic hydrogen into the component by a means of inducing a recombination of the atomic hydrogen to hydrogen gas. A method of reducing diffusion of atomic hydrogen into a component of a wind turbine by using such a coating is also provided.

摘要： The present disclosure is directed to a method of manufacturing a rotor blade for a wind turbine. The method includes providing a blade mold of the rotor blade. Another step includes placing an outer skin layer in the blade mold. The method also includes placing one or more structural inserts in the blade mold atop the outer skin layer as a function of a load of the rotor blade. Further, each of the structural inserts includes a plurality of cells arranged in a predetermined pattern. Further, the cells have varying cell sizes. The method also includes placing an inner skin layer atop the one or more structural inserts and securing the outer skin layer, the one or more structural inserts, and the inner skin layer together to form the rotor blade.

摘要： A production system for a wind turbine component is described. The system includes an elongate mold assembly extending in a longitudinal direction, the mold assembly comprising a mold surface and having a width that varies in the longitudinal direction. First and second tracks are defined respectively on opposite longitudinal sides of the mold surface. The perpendicular distance between the respective tracks varies along the length of the track. A transport assembly is moveable relative the mold assembly in the longitudinal direction. The transport assembly includes a pair of side supports arranged to move along the respective tracks, and a gantry supported above the mold assembly by the side supports. The gantry extends transverse to the longitudinal direction. The transport assembly is configured such that the side supports move relative to one another in a direction transverse to the longitudinal direction in accordance with the varying distance between the tracks as the transport assembly moves in the longitudinal direction.
