Abstract

A horizontal wind turbine with a tower supporting at least one blade, which is arranged to rotate about an axis, where one or more blades is moveable from a first position 1a adapted for low wind speed to a second position 2a in which the wind force exerted on the blades is reduced, allowing the turbine to operate at higher wind speeds. Preferably one or more blades is pivotable from a standard operating position perpendicular to the wind direction to a position parallel to the wind direction, allowing the turbine to continue to operate with a higher wind speed with the remaining blades. The blades may be mounted on supporting bearings with some blades being mounted in front of the bearings and some behind. A method of operating a wind turbine is also claimed.
