Dan Christian Bak, Thomas Buhl, Peter Fuglsang, Helge Aagaard Madsen, Flemming Rasmussen: Control of power, loads and/or stability of a horizontal axis wind turbine by use of variable blade geometry control. Technical University of Denmark, Stephen A Bent, Foley & Lardner, December 15, 2009: US07632068 (28 worldwide citation)

The present invention relates to a design concept by which the power, loads and/or stability of a wind turbine may be controlled by typically fast variation of the geometry of the blades using active geometry control (e.g. smart materials or by embedded mechanical actuators), or using passive geomet ...

Torben Juul Larsen, Helge Aagaard Madsen, Kenneth Thomsen: Method of controlling aerodynamic load of a wind turbine based on local blade flow measurement. Forskningscenter Riso, Hunton & Williams, November 4, 2008: US07445431 (19 worldwide citation)

The present invention relates to a method of controlling the aerodynamic load of a wind turbine's blades individually in such a way that the dynamic aerodynamic loads on the turbine are reduced and power production is optimised. In general the present invention will improve the overall stability of ...

A deformable trailing edge section (3) of a wind turbine blade (1), at least part of said section (3) being formed in a deformable material. The blade section (3) comprises one or more cavities (5) being in connection with or connectable to a fluid source in a way that allows fluid to stream from th ...
