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.
