20140127025 | WIND TURBINE ROTOR BLADE AND METHOD FOR INSTALLING A WIND TURBINE ROTOR BLADE - There is provided a wind power installation rotor blade having a rotor blade root, a rotor blade tip, a rotor blade leading edge, a rotor blade trailing edge, a pressure side and a suction side. The rotor blade further has a rotor blade outer casing with at least one opening in the pressure and/or suction side for receiving handling means for fitting or removing the rotor blade. The rotor blade also has at least one fixing unit for fixing the handling means which are introduced through the at least one opening. The fixing unit is arranged in the interior of the rotor blade outer casing between the pressure side and the suction side. | 05-08-2014 |
20140328691 | REAR CASING, ROTOR BLADE WITH REAR CASING, AND A WIND TURBINE THAT COMPRISES SUCH A ROTOR BLADE - The invention concerns a rear box section for a rotor blade, in particular of a wind power installation, comprising a pressure-side surface, a suction-side surface, a trailing edge separating the pressure-side and suction-side surfaces, and a connecting side which is opposite to the trailing edge and which is adapted for mounting to a corresponding connecting surface of the rotor blade. The invention concerns in particular a rear box section which is sub-divided into a foot segment having the connecting side and one or more head segments which have the trailing edge and which can be coupled to the foot segment. The invention also concerns a rotor blade for a wind power installation, and a wind power installation. | 11-06-2014 |
20140334934 | ROTOR BLADE AND CONNECTING DEVICE - A rotor blade of a wind power installation for fixing to a rotor hub and having a rotor blade longitudinal axis, including a rotor blade inner part towards the rotor hub, and a rotor blade outer part away from the rotor hub, wherein the rotor blade inner part and the rotor blade outer part are connected together by means of at least one connecting device and the connecting device includes at least one anchoring element anchored in the rotor blade outer part, at least one counterpart element anchored in the rotor blade inner part, and at least one connecting bolt which extends through the counterpart element and is fixed in the anchoring element. | 11-13-2014 |
20150266250 | APPARATUS AND METHOD TO MANUFACTURE SEMI-FINISHED PRODUCTS FOR WIND POWER INSTALLATION ROTOR BLADES AS WELL AS ROTOR BLADE AND WIND POWER INSTALLATIONS - An apparatus to manufacture semi-finished blade end products for wind power installation rotor blades with a winding mandrel which can be rotated for rolling up preferably ribbon-like fiber composite materials. | 09-24-2015 |
20150308414 | WIND TURBINE - The invention relates to a wind energy plant with a nacelle, a generator located in the nacelle, a tower and a yaw bearing to adjust the nacelle orientation into the wind, such that the yaw bearing is located under the nacelle in a vertical yaw displacement and the nacelle is supported on the yaw bearing above a vertical shaft section of the same length as the yaw displacement. | 10-29-2015 |
20160090963 | ROTOR BLADE TIP - A rotor blade of a wind energy plant having a main component of the blade and a blade tip, whereby the blade tip is releasably attached to the main component by means of a connection device and the connection device has a tip section attached to the blade tip and a base section attached to the main component of the blade to receive the tip section, whereby the tip section has at least one fastener that extends to the base section for attaching the tip section to the base section, and the fastener for performing the attachment can be actuated through an opening in the surface of the blade tip. | 03-31-2016 |
