Patent number: 11181093Abstract: A rotor blade for a wind turbine is provided. The rotor blade includes a pressure side, a suction side, a leading edge section with a leading edge, and a trailing edge section with a trailing edge. An airflow flows along the surface of the rotor blade from the leading edge section to the trailing edge section and builds up a boundary layer in close proximity to the surface of the rotor blade. The rotor blade includes a noise reduction device for reducing noise which is generated by interaction of the airflow and the rotor blade. The noise reduction device is located within the boundary layer of the rotor blade. The noise reduction device includes a cover and connection device for connecting the cover to the surface of the rotor blade. The cover spans at least over a part of the surface of the rotor blade.Type: GrantFiled: July 30, 2014Date of Patent: November 23, 2021Inventors: Michael J. Asheim, Kristoffer Ahrens Dickow, Peder Bay Enevoldsen, Alex Loeven, Valerio Lorenzoni, Stefan Oerlemans, Anders Smaerup Olsen, Bodo Richert, Manjinder J. Singh, Sigmund Wenningsted Torgard

Patent number: 10247169Abstract: A rotor blade for a wind turbine with an aerodynamic device, and an aerodynamic device is provided. The rotor blade includes a main body defining a pressure side and a suction side of the rotor blade, and includes a main body trailing edge section. The rotor blade includes an aerodynamic device with an attachment section for attaching the aerodynamic device to the main body trailing edge section, an aerodynamic section for influencing the aerodynamic properties of the rotor blade, and a buckling section for controlling the orientation and/or the shape of the aerodynamic section with regard to the main body. The aerodynamic device is configured such that it deforms elastically for a force component acting in flapwise direction on the buckling section, and deforms abruptly if a force component of about the size of the stability limit of the buckling section acts in flapwise direction on the buckling section.Type: GrantFiled: January 22, 2015Date of Patent: April 2, 2019Assignee: Siemens AktiengesellschaftInventors: Alejandro Gomez Gonzalez, Alex Loeven, Sigmund Wenningsted Torgard

Patent number: 9879541Abstract: A rotor blade with a supporting structure, wherein the rotor blade has a rotor blade base section and a rotor blade tip section, is provided. The supporting structure includes a first supporting segment for supporting the rotor blade base section and at least a second supporting segment for supporting the rotor blade tip section. Furthermore, the supporting structure includes the first supporting segment and the second supporting segment along the rotor blade longitudinal direction. The first supporting segment is joined to the second supporting segment in a supporting structure transition section, wherein the supporting structure transition section is located in between the rotor blade base section and the rotor blade tip section. Finally, the first supporting segment and/or the second supporting segment include a fiber material. A method for manufacturing the rotor blade is also provided.Type: GrantFiled: March 9, 2014Date of Patent: January 30, 2018Assignee: Siemens AktiengesellschaftInventor: Sigmund Wenningsted Torgard
