20110171038 | WIND TURBINE ROTOR BLADE AND PRODUCING METHOD OF WIND TURBINE ROTOR BLADE - A wind turbine rotor blade includes an outer skin material formed of fiber-reinforced plastic, main strength materials (super cap materials) disposed on inner surfaces of a back side and a front side of the outer skin material, and crossbeam materials (sheer webs) disposed between the main strength materials, wherein the main strength material is formed by stacking, one on top of another, reinforced fiber sheets having constant widths in a longitudinal direction. | 07-14-2011 |
20110182742 | WIND TURBINE BLADE AND WIND TURBINE GENERATOR USING THE SAME - A wind turbine blade includes a laminated structure having an outer shell ( | 07-28-2011 |
20120100002 | WIND TURBINE ROTOR BLADE - Provided is a wind turbine rotor blade that can secure a sufficient strength in a coupling portion without significant increase in weight even though a blade is increased in size because beams, which are main strength members of the separated blades, are coupled to each other by metallic coupling members. A wind turbine rotor blade including: a skin that forms a long hollow shape; and a beam that is vertically passed in a longitudinal direction to reinforce the skin from inside, wherein the beam is separated into at least two portions in the longitudinal direction, and ends of the adjacent beams are coupled to each other through a metallic coupling member having: a first flange portion opposed to the one end; a second flange portion opposed to the other end; and a connecting portion that connects these first flange portion and second flange portion, and the skin is separated into a coupling portion skin arranged at a position corresponding to the coupling member, and a main body skin arranged at a position corresponding to the beam. | 04-26-2012 |
20120186730 | REINFORCEMENT FABRIC LAMINATING APPARATUS AND METHOD FOR THE SAME - Provided are a reinforcement fabric laminating apparatus and a method for the same in which wrinkles that occur when a sheet-like reinforcement fabric is laminated on a curved or bent mold can be prevented, the workload can be reduced, and the operating efficiency can be improved. A reinforcement fabric laminating apparatus including a sheet feeding unit that feeds out a reinforcement fabric to be laminated on a mold and a pressure contact unit that pressure-contacts the reinforcement fabric onto the mold, wherein the pressure contact unit has a narrower width than the reinforcement fabric, and the sheet feeding unit supplies the reinforcement fabric while applying tension between the sheet feeding unit and the pressure contact unit. | 07-26-2012 |
20130129511 | WIND TURBINE AND APPARATUS AND METHOD FOR DETECTING DAMAGE TO WIND-TURBINE-BLADE SKIN - An object is to provide a wind turbine and an apparatus and method for detecting damage to a wind-turbine-blade skin, which can reduce the workload of workers who are in charge of inspection for damage to a wind-turbine-blade skin. Provided is an apparatus for detecting damage to a wind-turbine-blade skin that detects damage to the skin of a wind turbine blade having a hollow structure, the apparatus including a pressure sensor that measures the internal pressure of the wind turbine blade; and a nacelle-side control unit that detects damage based on the pressure measured by the pressure sensor. | 05-23-2013 |
20130149154 | WIND TURBINE BLADE - A wind turbine blade having a lightning protection function includes an outer shell, a spar arranged in a space inside the outer shell, a spar cap which is formed by a carbon-fiber plastic laminated member disposed on a blade root side and a glass-fiber plastic laminated member disposed on a blade tip side that are connected together, the spar cap supporting the spar to the outer shell, and a lightning protection unit. The lightning protection unit includes a receptor for receiving lightning which is provided in the outer shell on a side where the glass-fiber plastic laminated member is arranged, a down conductor which directs lightning current received by the receptor into the ground or the water, and a conductive metal member which covers the outer shell on a side where the carbon fiber plastic laminated member is arranged. | 06-13-2013 |
20130220005 | WIND TURBINE BLADE, METHOD FOR MANUFACTURING WIND TURBINE BLADE, AND WIND POWER GENERATOR AND WIND TURBINE BLADE MONITORING SYSTEM INCLUDING WIND TURBINE BLADE - A wind turbine blade used in a wind power generator that receives wind and rotates a rotating shaft of a generator includes at least two layers on a surface of a blade body, one of the layers being colored with a coating material different in color from the blade body and the rest of the layers. The layers are provided at least on a tip, particularly at a front edge of the wind turbine blade. A wind turbine blade monitoring system that monitors the wind turbine blade includes: an imaging unit that images the wind turbine blade in a predetermined position over a predetermined period at timing when the wind turbine blade passes through the predetermined position; and an indication unit that chronologically indicates imaging results of the wind turbine blade imaged by the imaging means. | 08-29-2013 |
20130221568 | METHOD AND APPARATUS FOR MANUFACTURING FIBER-REINFORCED BASE MATERIAL - It is intended to provide a method and an apparatus for manufacturing a fiber-reinforced base material, which is capable of manufacturing a fiber-reinforced base material of high quality while preventing generation of defects such as wrinkles during stacking of the base material sheet. The method for manufacturing the fiber-reinforced base material formed by stacking a base material sheet including a reinforcement fiber onto a mold having a double-curved surface shape, includes steps of: supplying the base material sheet onto the mold from a base material roll while applying distribution varying in a width direction (X direction) to a length of the base material sheet in a sheet-supplying direction of the base material sheet (Y direction) in correspondence with the double-curved surface shape of the mold; and applying pressure to the base material sheet in contact with the mold. | 08-29-2013 |
