Wind turbine

A wind turbine comprising a tower, a nacelle mounted on the tower, and a rotor mounted to the nacelle,

• the rotor comprising a hub and at least three pitchable wind turbine blades connected to the hub via respective pitch mechanisms,
• each blade extending from a blade root defining a radial position r=0 to a blade tip defining a radial position r=R;
• each blade comprising a windward side and a leeward side which meet at a leading edge and a trailing edge to define an airfoil profile, a chord being a distance between the leading and trailing edges, and a relative thickness being a ratio of thickness to chord, the airfoil profile having a thickness being the greatest distance between the windward and leeward sides orthogonal to the chord;
• each blade comprising a connection point located at a first radial position (r1) between the blade root and the blade tip, wherein the connection point is located at a part of the blade that is pitchable, and the wind turbine further comprising one or more blade connecting members connected between the connection point and a corresponding connection point on a neighbouring blade,
• wherein the thickness and/or the relative thickness of each blade is substantially constant or has a local minimum within an inboard portion of the blade between the blade root and the connection point.
