Abstract: A blade mould and a method for manufacturing a blade shell part of a wind turbine blade is disclosed. The blade mould comprises a first mould frame; a mould shell supported by the first mould frame and provided with a moulding surface that defines an outer shape of the blade shell part, wherein the mould shell has a longitudinal direction and comprises a root end mould part at a first end thereof; and a first deformation device for deforming the root end mould part of the mould shell. The method comprises arranging reinforcement material on the moulding surface of the root end mould part; deforming the root end mould part to a receiving configuration; inserting the root end insert in the root end mould part; and bringing the root end mould part to a moulding configuration.

Abstract: A control method for a wind turbine, in particular for a wind turbine blade is described. The control method makes use of the blade mode shapes, or natural vibration shapes, of the blade to detect the excitement level of the blade natural vibrations, and controls active lift devices on the blade in an effort to reduce the excitement levels, to reduce loading in the blade and the overall wind turbine structure. There is also provided a method of designing a wind turbine blade for use in such a method.

Abstract: A turning device, for manufacturing wind turbine blades and turning moulds relative to each other, having a base, a rotational part movable relative to the base on an rotational axis, a first linear actuator with first and second ends, the first end attaching to the base, and the second end attaching to the rotational part at a first anchor point on a first turning axis, and a second linear actuator having first and second ends, the first end attaching to the base, and the second end attaching to the rotational part at a second anchor point on a second turning axis. The first turning axis is a first distance from the rotation axis and is moved on a first arc on the rotation axis, and the second turning axis is a second, different distance from the rotation axis and is moved along a second arc on the rotation axis.
