摘要： A method is provided for operating a wind turbine having an elongated stand apparatus, a generator rotatably mounted on the stand apparatus, and a rotor coupled to the generator via a rotor hub and the wind turbine also having an elongated rotor blade. A position of a radar system is determined with respect to the wind turbine and at least one area is determined for the rotational axis of the rotor as a function of the determined position which is not intended to be permanently assumed for alignment of the rotational axis of the rotor about the longitudinal axis of the stand apparatus. The wind turbine is operated with the at least one determined area not being permanently assumed for the alignment of the rotational axis of the rotor about the longitudinal axis of the stand apparatus.

摘要： A wind turbine electrical generator may include a monopole tower extending upwardly from ground level. The wind turbine electrical generator may also include an electrical power generator carried by an upper end of the monopole tower and may include a horizontally extending drive shaft. The wind turbine electrical generator may further include a plurality of wind-driven blades carried by the horizontally extending drive shaft. The monopole tower may have an outer surface with a vertically extending outer corner therein defining a pair of adjacent vertical facets. The monopole tower may be positioned with the vertically extending outer corner aligned with the land-based radar site so that the pair of adjacent vertical facets reflects radar illumination away from the radar site to reduce an amount of the radar illumination reflected back to the land-based radar site.

摘要： A combined omnidirectional flow turbine system includes rotors that are disposed in a vertical position and enclosed in a motionless structure that receives air flows from any external direction which are manipulated by an airfoil to cause the rotors to rotate. The motionless structure is a hollow body and it is formed by a support structure and cover, being said interior space adapted to store electronic components, which can be directly supplied by the energy, produced. On its outer surface, air particles and pollutants filters can be installed, taking advantage of the aerodynamic shape of the motionless structure, which promotes air flow adhesion along its surface, making possible to capture particles along their preferred path.

摘要： A split core for a composite structure is described. The split core includes a first core layer, a second core layer, and a functional interlayer disposed between the first and second core layers. The first core layer separates the functional interlayer from a functional layer of the composite structure and/or from an outer surface of the composite structure. The thickness of the first core layer is substantially uniform across the composite structure and the distance between the functional interlayer and the functional layer and/or the outer surface of the composite structure is substantially constant across the composite structure.
