Wind turbine blade with extended shell section

摘要

The present invention relates to a manufacturing method for wind turbine blade and a wind turbine manufactured according to that method. The wind turbine blade comprises two shell parts wherein each shell part has a leading edge connected to a trailing edge via an inner surface. One of the two shell parts comprises an extended shell section which is configured as a flexible shell section. The shell section is configured to flex in a radial direction from a first position to a second position relative to the leading edge when an incoming wind is acting on the pressure side of the wind turbine blade. The wind turbine blade may be manufactured using a non-bonding layer removable arranged adjacent to the glue line between the two shell parts which reduces the amount of manual grinding or polishing of the glue region. This provides a wind turbine blade with an improved blade characteristic where the extended flexible shell section is specifically designed to have significant flexibility. The configuration provides a method for passively controlling the lift of the wind turbine blade.
