20110044817 | Method for Establishing A Blade Connection of a Rotor Blade, A Blade Connection and a Securing Element for a Blade Connection - The invention relates to a process for manufacturing a blade connection of a rotor blade for a wind energy system which comprises fastening elements for fastening the blade connection to a hub, which fastening elements are provided on a circular arc, preferably equidistant from each other. Furthermore, the invention relates to a blade connection and a fastening element for a blade connection. The invention is based on the problem of improving the fastening of a rotor blade on the hub of a wind energy system as well as improving the manufacture and/or making a suitable blade connection available. The invention solves this problem as regards the process in that fastening elements formed in pieces are arranged on the circular arc and spaced from each other with spacer elements. | 02-24-2011 |

20110142679 | ROTOR BLADE FOR A WIND TURBINE, METHOD AND MANUFACTURING MOLD FOR THE PRODUCTION THEREOF - A rotor blade and a method and a manufacturing mold for the production of a rotor blade for a wind turbine, which extends longitudinally in the operational state from a blade root area to the connection to a rotor hub of the wind turbine and which is divided into at least two segments for its production, wherein at least one subdivision is provided approximately transverse to its longitudinal extension between the blade root area and the blade tip. The method facilitates and shortens the production of the rotor blade, in particular for a series production and to still provide the completed rotor blade as a familiar uniform rotor blade. In the method, the at least two segments, preferably after they have been at least partially produced or partially produced mainly parallel in time, are interconnected in an integration device. | 06-16-2011 |

20120148404 | ROTOR BLADE ATTACHMENT - A rotor blade attachment, in particular of a wind power plant, for the connection of a rotor blade with an attachment device, including a transverse pin and a connecting device, which can be brought together to establish an operative connection, wherein the connecting device defines a longitudinal axis. The rotor blade attachment is characterized in that the transverse pin in the direction of the longitudinal axis of the connecting device has a higher bending stiffness than transversally to the longitudinal axis. An alternative rotor blade attachment is characterized in that the transverse pins are arranged in at least two rows, wherein at least a first row is arranged closer to the blade-root-side end of the rotor blade than at least a second row. | 06-14-2012 |
