发明名称 UPWIND WIND TURBINE WITH BLADES SUPPORTED ON THE LEEWARD SIDE
摘要 A wind turbine comprising a number of blades extending substantially radially from a rigid hub on a main shaft having a substantially horizontal axis. The blades together with the hub constituting a rotor with a rotor plane, which can be put into rotation by wind. The main shaft is pivotally mounted in a nacelle mounted on top of a tower, the nacelle being able to pivot around a vertical axis in relation to the tower, hereby being able to adjust the rotor plane of the blades in relation to a direction of the wind. The wind turbine is an upwind machine in that the rotor during normal use of the wind turbine is positioned on the upwind side of the tower. The rotor during normal use of the wind turbine having a windward side and a leeward side, and each blade having an innermost part comprising a root section of the blade and an outermost part comprising a tip section of the blade. Each blade is supported on the leeward side by at least a first leeward supporting means having a first end and a second end, the first end being connected to the blade at a first leeward mounting point positioned in a radial distance from the horizontal axis, and the second end being connected to a second leeward mounting point at a rotatable part of the wind turbine, the second leeward mounting point being positioned in an axial distance from the rotor plane on the leeward side of the rotor.
