Embodiment Construction

[0065] 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 having a blade root 16 closest to the hub and a blade tip 14 furthest from the hub 8 . The rotor has a radius marked R.

[0066] figure 2 A schematic view of a wind turbine blade 10 is shown. The 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 the root region 30 and the airfoil region 34 District 32. The blade 10 comprises a leading edge 18 facing the direction of rotation of the blade 10 when the blade is mounted on the hub and a trailing edge 20 facing in the opposite direction of the leading edge 18 .

Abstract

The present invention relates to a method of manufacturing a wind turbine blade comprising the steps of manufacturing a pressure shell halves and arranging a spar structure (62) within one of the shell halves. The spar structure (62) comprises two parts releasably coupled to each other. The method results in a segmented wind turbine blade for easy transportation and re-assembly.

Description

technical field [0001] The invention relates to a method of manufacturing a wind turbine blade, and to a wind turbine blade obtainable by said method. Background technique [0002] Wind power provides a source of clean and environmentally friendly energy. A wind turbine typically includes a tower, generator, gearbox, nacelle, and one or more rotor blades. Wind turbine blades capture the kinetic energy of the wind using known airfoil principles. Modern wind turbines may have rotor blades exceeding 90 meters in length. [0003] Wind turbine blades are typically manufactured by forming two shell parts or shell halves from layers of woven fabric or fibers and resin. Spar caps or primary laminates are placed or integrated into the shell halves and can be combined with shear webs or spar rods to form structural support members. The spar caps or main laminates may be joined to the inside of the suction and pressure halves of the shell, or integrated within the inside of the suc...
