Abstract: A wind turbine comprising includes a tower, a nacelle mounted on the tower, and a rotor mounted to the nacelle. The rotor comprises a hub and at least three pitchable wind turbine blades connected to the hub via respective pitch mechanisms. The airfoil profile of each blade has a thickness being the greatest distance between the windward and leeward sides orthogonal to the chord. Each blade comprises a connection point located at a first radial position between the blade root and the blade tip. The wind turbine further comprises one or more blade connecting members connected between the connection point and a corresponding connection point on a neighbouring blade. 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.
