Abstract
A wind turbine for a wind turbine electrical generator set in which movable nose portions are located at or adjacent the leading edge of the blade and at or adjacent the tip of the blade but is dispaceable purely longitudinally of the blade, i.e. radially outwardly of the blade, from the normal retracted position, in which the portion contributes to the lift of the aerofoil section, to an advanced position in which drag is produced, to prevent unwanted increase in the speed of the rotation of the rotor.
