Embodiment Construction

[0055] figure 1 A conventional modern upwind wind turbine 2 according to the so-called "Danish concept" is illustrated with a tower 4, a nacelle 6 and a rotor with a substantially horizontal rotor axis. The rotor comprises a hub 8 and three blade assemblies 10 extending radially from the hub 8 , each blade assembly having a blade root 16 closest to the hub and a blade tip 14 furthest from the hub 8 .

[0056] figure 2 A schematic diagram of an exemplary wind turbine blade assembly 10 is shown. The wind turbine blade assembly 10 extends along the longitudinal axis L, has a root end 17 and a tip end 15, and has the shape of a conventional wind turbine blade having a profile region comprising a root region 12 closest to the hub, a region furthest from the hub, or The airfoil region 11 and the transition region 13 between the root region 12 and the airfoil region 11 . The blade assembly 10 includes a leading edge 18 facing the direction of rotation of the blade assembly 10 whe...

Abstract

A wind turbine blade assembly and a method for manufacturing the same are disclosed. A wind turbine blade assembly includes a leading edge, a trailing edge, a blade shell having a trailing section, and a flat back profile member. The aft section has an outwardly curved arcuate shape, and the flat back profile is positioned so as to cover the aft section of the blade shell.

Description

technical field [0001] The invention relates to wind turbine blade assemblies and to methods of their production. A wind turbine blade assembly includes a blade shell and a flatback profile part. The profile of the wind turbine blade assembly is implemented as a flatback profile. Background technique [0002] As wind turbines and wind turbine blades increase in size, blade loads (ie strains, bending moments, peel loads, etc.) increase, especially along the trailing edge. For this and other reasons, the design of the rear edge is an important factor for the efficiency of the wind turbine. [0003] Wind turbine blades comprising a flatback profile at the trailing edge may in some cases have improved efficiency. The optimized profile includes a varying geometry along the trailing edge of the airfoil region of the blade. Rounded corners may be required in flat-back profiles, which are produced as an integral part of the housing part. This is bad for aerodynamic performance....
