Embodiment Construction

[0109] figure 1 A conventional modern upwind wind turbine according to the so-called "Danish concept" is illustrated with a tower 4, a nacelle 6 and a rotor with a substantially horizontal rotor shaft. The rotor comprises a hub 8 and three blades 10 extending radially from the hub 8 , each blade 10 having a blade root 16 closest to the hub and a blade tip 14 furthest from the hub 8 .

[0110] figure 2 A schematic view of a first embodiment of a wind turbine blade 10 according to the invention is shown. Wind turbine blade 10 has the shape of a conventional wind turbine blade and includes a root region 30 closest to the hub, a profile or airfoil region 34 furthest from the hub, and a transition between root region 30 and airfoil region 34 Area 32. The blade 10 comprises a leading edge 18 and a trailing edge 20 , the leading edge 18 facing the direction of rotation of the blade 10 when the blade is mounted on the hub and the trailing edge 20 facing in the opposite direction o...

Abstract

The present invention relates to a manufacturing system and to a method for the manufacture of preforms for wind turbine blade parts. The system comprises two or more preform moulds (70), a fibre lay-up station (88) for placing a fibre material into the preform moulds (70), and a heating station (90) for heating the fibre material to form the preforms. At least two of the preform moulds (70) havesubstantially identical width W and substantially identical height H.

Description

technical field [0001] The present invention relates to a manufacturing system and method for manufacturing preforms for wind turbine blade components. Background technique [0002] The rotor blades of modern wind turbines capture kinetic wind energy by using complex blade designs that are generated to maximize efficiency. There is an increasing demand for large wind blades that may exceed 80 meters in length and 4 meters in width. Typically, the blade is made of fibre-reinforced polymer material and comprises a pressure side shell half and a suction side shell half, also called a blade half. The cross-sectional profile of a typical blade includes an airfoil for creating a flow of air that creates a pressure difference between the two sides. The resulting lift creates torque that is used to generate electricity. [0003] The shell halves of wind turbine blades are typically manufactured using blade moulds. First, a blade gel coat or primer is applied to the mold. Subseq...
