Problems solved by technology

As a result, damage can result in the connection area or at the trailing edge section and / or at the rotor blade
Furthermore, therefore, the design of the connecting regions has hitherto been complex and expensive
Furthermore, the amount of connecting material required, such as adhesives or other connecting elements, is very high and thus expensive

Embodiment Construction

[0039] figure 1 A wind energy installation 100 is shown with a tower 102 and a nacelle 104 . Arranged on the nacelle 104 is a rotor 106 having three rotor blades 1 and a spinner 110 each having a trailing edge section 112 . The rotor blades 1 are each fastened to a hub 105 . In operation, the rotor 106 is set in rotational motion by the wind to drive a (not shown) generator in the nacelle 104 .

[0040] figure 2 A partial view of a rotor blade 1 of a wind energy installation is shown with a longitudinal axis L, an inner blade section 3 , a trailing edge section 2 and a blade root 4 . In the region of the blade root 4 the rotor blade 1 has the greatest profile depth. In this case, the blade separation point or blade separation flange 3 is arranged on the inner blade section 3 . A further blade section can be arranged on the blade separation point or the blade separation flange and form the aerodynamic contour of the rotor blade 1 . The trailing edge portion 2 can optiona...

Abstract

The invention relates to a rotor blade of a wind energy installation. The rotor blade comprises: a blade root for connecting the rotor blade to the rotor hub; an inner blade section extending from the blade root in the direction of the longitudinal axis of the rotor blade; at least one trailing edge portion section of the trailing edge portion of profile depth on the root; and at least one first and second securing region for securing the at least one trailing edge portion section of the trailing edge portion to the inner blade section part. In this case, the first fastening section is arranged at a predetermined distance from the second fastening section in the direction of the longitudinal axis of the rotor blade, and at least one trailing edge section section of the trailing edge section is fastened to the inner blade section such that The loads occurring on the inner blade section are transferred pointwise to at least one trailing edge section section of the trailing edge section via the first and the second fastening section.

Description

technical field [0001] The invention relates to a rotor blade of a wind energy installation of a wind energy installation having at least one trailing edge part section and an inner blade section, the invention relates to a wind energy installation and a device for arranging the trailing edge The method by which a partial segment is joined to the inner blade segment of a rotor blade. Background technique [0002] The design of the rotor or the rotor is important for the efficiency of the wind power plant. One possibility of increasing the efficiency and the effective power of a wind energy plant via the design of the rotor blade is to form the profile of the rotor blade with a large profile depth in the area of ​​the rotor blade root, i.e. the rotor blade is formed between the rotor blade trailing edge and the rotor blade The length between the flanges is designed to be as large as possible. In this case, the region of the rotor blade root is to be understood as the region...
