Abstract

A blade of a wind turbine is presented. This blade is provided with a root section for connecting the blade to the shaft or hub of the turbine. The blade also contains a wind-energy-absorbing profile which is optimized for wind flow. The output of the wind turbine is increased by providing the root section with a member that is designed in such a way that the assembly consisting of said member and the root section can absorb wind energy and will increase the overall efficiency of the wind turbine.
