Wind turbine blade with extended shell section

A wind turbine comprising:

• a wind turbine tower having a top;
• a nacelle coupled to the top of the wind turbine tower via a yaw system;
• a rotor hub rotatably mounted to the nacelle;
• one or more wind turbine blades having a tip end located in the opposite end of a blade root configured to be mounted to the rotor hub, where the wind turbine blade comprises a pressure side connected to a suction side via a leading edge, wherein the wind turbine blade further comprises a first shell part having a first trailing edge connected to a first inner surface facing a second shell part, wherein the second shell part has a second trailing edge connected to a second inner surface facing the first shell part, wherein one of the two shell parts comprises an extended shell section where the trailing edge of the other shell part is coupled to the inner surface of that shell part, e.g. via a glue line;
• and
• wherein
• the extended shell section is configured as a flexible shell section for load reduction where the first trailing edge is configured to move from a first position to a second position in a direction towards the suction side relative to the first leading edge when an incoming wind is acting on the pressure side of the wind turbine blade, and
• wherein
• the chord (C) of the wind turbine blade has a relative length of 1 and the extended shell section has a relative width on at least 0.10.
