Abstract: A pitch controlled wind turbine (1) comprising a tower (2), a nacelle (3) mounted on the tower (2), a hub (4) mounted rotatably on the nacelle (3), and at least three wind turbine blades (5) is disclosed. Each wind turbine blade (5) extends between a root end (6) connected to the hub (4), and a tip end (7). The wind turbine (1) further comprises at least three blade connecting members (8), each blade connecting member (8) extending between a connection point (9) on one wind turbine blade (5) and a connection point (9) on a neighbouring wind turbine blade (5). The wind turbine blades (5) each comprises an inboard blade part (5a) comprising the root end (6) and an outboard blade part (5b) comprising the tip end (7), the inboard blade part (5a) and the outboard blade part (5b) being connected to each other at a split position (10). The split position (10) is arranged between the root end (6) and the connection point (9).

Abstract: A horizontal axis wind turbine (1) with a wind turbine blade (5) is disclosed, the wind turbine blade (5) comprising a hinge (6) arranged to connect the wind turbine blade (5) to a blade carrying structure (4) of the wind turbine (1), at a non-zero distance from an inner tip (5a) and at a non-zero distance from an outer tip (5b) of the wind turbine blade (5). An outer blade part (7) is arranged between the hinge region and the outer tip (5b), and an inner blade part (8) is arranged between the hinge region and the inner tip (5a). The outer blade part (7) extends from the hinge region along a first direction and the inner blade part (8) extends from the hinge region along a second direction, and the first direction and the second direction form an angle, α, there between, where 0°

Abstract: A pitch controlled wind turbine comprising a tower, a nacelle mounted on the tower, a hub mounted rotatably on the nacelle, and at least three wind turbine blades is disclosed. Each wind turbine blade extends between a root end connected to the hub via a pitch mechanism, and a tip end. The wind turbine further comprises at least three blade connecting members, each blade connecting member extending between a connection point on one wind turbine blade and a connection point on a neighboring wind turbine blade, the connection points being arranged at a distance from the root end and at a distance from the tip end of the wind turbine blade. The wind turbine further comprises at least three pre-tension members, each pre-tension member being connected to one of the blade connecting members and to a hub part, the pre-tension members thereby providing pre-tension in the blade connecting members.
