Publication number: 20230084177Abstract: A wind turbine blade includes a profiled contour with a leading edge and a trailing edge, and a chord extending between the leading edge and the trailing edge, along with a blade shell with a pressure side and a suction side, a first main spar cap integrated in the pressure side of the blade shell, a second main spar cap integrated in the suction side of the blade shell, and one or more shear webs connected between the first main spar cap and the second main spar cap. The blade shell includes at least a first load carrying structure arranged at the leading edge or the trailing edge and having a first extension, including a first primary extension on a first side of the chord, where the first primary extension is at least 60% of the first extension.Type: ApplicationFiled: May 27, 2022Publication date: March 16, 2023Applicant: LM WIND POWER US TECHNOLOGY APSInventors: Morten RAVN, Peter HANSEN, Simon BERG BOJESEN, Casper SKOVBY, Mads DØSSING, Peter BÆK, Christian Frank ANDERSEN, Michael KLITGAARD, Mark Olaf SLOT

Patent number: 10662807Abstract: Method and blade monitoring system for monitoring bending moment of a wind turbine blade. The method comprises obtaining a first sensor set signal indicative of a first bending moment at a first sensor position different from the tip end along the longitudinal axis of the wind turbine blade, and estimating a bending moment at a first estimation position along the longitudinal axis based on the first sensor set signal, wherein the first sensor position is different from the first estimation position along the longitudinal axis. The blade monitoring system comprises a processing unit and an interface connected to the processing unit, the processing unit being configured for performing the method.Type: GrantFiled: January 5, 2017Date of Patent: May 26, 2020Assignee: LM WP PATENT HOLDING A/SInventor: Casper Skovby

Patent number: 10330082Abstract: A system for monitoring the deflection of a wind turbine blade is described. The system comprises a wireless range-measurement system, having at least one wireless communication device located towards the root end of the blade and at least one wireless communication device located towards the tip end of the blade. The root end device is provided on a bracket projecting from the external surface of the blade, to provide a communication path between the root end and tip end devices which is less susceptible to interference from multipath effects, etc. There is further provided a method to derive tilt and yaw moments from measured deflections. A control method for such a system is also described, wherein the signal gain of the communication path may be varied based at least in part upon the deflection characteristics of the wind turbine blade.Type: GrantFiled: August 14, 2013Date of Patent: June 25, 2019Assignee: LM WP PATENT HOLDING A/SInventors: Claus Byskov, Peter Baek, Michael Klitgaard, Casper Skovby, Lars Fuglsang

Patent number: 10316817Abstract: A manufacturing method is described for a wind turbine blade, where layers of fiber material are laid up in a mold to form a portion of the blade structure. The fiber layers are infused with a resin which is subsequently cured to form the hardened blade structure. Some of the layers of fiber material are arranged so that a portion of the layers are kept resin-free during the infusion and curing steps, so that the fiber layer extends freely out from the external surface of the blade, preferably at the blade trailing edge, to provide a flexible blade trailing edge to reduce blade operational noise.Type: GrantFiled: April 28, 2015Date of Patent: June 11, 2019Assignee: LM WP PATENT HOLDING A/SInventors: Michael Klitgaard, Christian Frank Andersen, Morten Ravn, Casper Skovby, Simon Berg Bojesen, Peter Baek

Patent number: 9909562Abstract: A control method for a wind turbine, in particular for a wind turbine blade is described. The control method makes use of the blade mode shapes, or natural vibration shapes, of the blade to detect the excitement level of the blade natural vibrations, and controls active lift devices on the blade in an effort to reduce the excitement levels, to reduce loading in the blade and the overall wind turbine structure. There is also provided a method of designing a wind turbine blade for use in such a method.Type: GrantFiled: December 5, 2012Date of Patent: March 6, 2018Assignee: LM WP PATENT HOLDING A/SInventors: Peter Baek, Christian Frank Andersen, Mark Olaf Slot, Casper Skovby, Simon Berg Bojesen, Morten Ravn, Michael Klitgaard
