Abstract: A wind turbine includes a number of blades and an optical measurement system comprising a light source, such as a laser, an optical transmitter part, an optical receiver part, and a signal processor. The light source is optically coupled to the optical transmitter part, which includes an emission point for emitting light in a probing direction. The optical receiver part comprises a receiving point and a detector. The optical receiver part is adapted for receiving a reflected part of light from a probing region along the probing direction and directing the reflected part of light to the detector to generate a signal used to determine a first velocity component of the inflow. The emission point is located in a first blade at a first radial distance from a center axis, and the receiving point is located in the first blade at a second radial distance from the center axis.

Abstract: An upwind wind turbine comprising blades extending radially from a rigid hub on a main shaft having a horizontal axis is described. The blades and hub constitute a rotor with a rotor plane. The main shaft is pivotally mounted in a nacelle on top of a tower which pivots around the vertical axis of the tower. The rotor plane adjusts in relation to wind direction, so during normal use the rotor is positioned on the upwind side of the tower. Each blade has at least a first leeward supporting mechanism having first and second ends. The first end connects to the blade at a first leeward mounting point positioned in a radial distance from the horizontal axis. The second end connects to a second leeward mounting point at a rotatable part and is positioned in an axial distance from the rotor plane on the leeward side of the rotor.

Abstract: The present invention relates to a table for a wind turbine equipped with attachment devices 103 for attaching servicing equipment, 401, 402, said attachment means being attached at and accessible from the blade exterior. They may be located in cavities and be covered when not in use. Hereby it is accomplished that the blade can be serviced and repaired while positioned horizontally without the attachment devices as such otherwise influencing the aerodynamic properties of the blade. One possibility is that during manufacturing such a cavity is closed but the cavity can later be broken open. Additionally, the invention relates to a wind turbine featuring such blade and a method of servicing a blade when mounted on a wind turbine, wherein servicing equipment is attached to at least one attachment device in the blade. It is furthermore mentioned, that the attachment devices might be used when mounting a blade.
