Embodiment approach 1

[0091] Embodiment 1: Edge arc of a rotor blade for a wind energy installation, wherein the edge arc has a first section of at least one first electrically conductive material and a second section of a second non-conductive material part.

Embodiment approach 2

[0092] Embodiment 2: Edge arch according to embodiment 1, characterized in that the first material is metal, in particular aluminum, or comprises metal, and / or the second material is glass fiber reinforced plastic (GFK) or carbon fibers Plastic reinforced (CFK) or plastic reinforced with glass fibers (GFK) or plastic reinforced with carbon fibers (CFK).

Embodiment approach 3

[0093]Embodiment 3: Edge arch according to Embodiment 1 or 2, characterized in that the edge arc has, in its second section, a connection for connection to a rotor blade, in particular for insertion into a rotor blade area, and the edge arc has in its first section an edge arc tip facing away from the connection area, wherein the edge arc tip has the first material and the connection area has the second material.

Abstract

The invention relates to a rotor blade (30) of a wind energy installation (100) having a blade main part and a blade tip (260), wherein the blade tip (260) is detachably connected by means of a connecting device (202) fixed on the main part, and the connection device (202) has a tip section (206) fixed on the blade tip (260) and a base part fixed on the blade main part for receiving the tip section (206) segment (204), wherein the tip segment (206) has at least one securing mechanism (242) extending to the base segment (204) for securing the tip segment (206) to the base segment (204) , and the securing mechanism (242) is operable through an opening (286) in the surface (282) of the blade tip (260) for securing.

Description

technical field [0001] The invention relates to a rotor blade of a wind energy installation having a blade main part and a blade tip. Furthermore, the invention relates to a connecting device for connecting such a blade main part to a rotor blade tip, and the invention relates to a rotor blade tip, which is also referred to below for simplicity as blade tip part, and the invention relates to a method for mounting a blade tip on a main part of a rotor blade. Background technique [0002] An edge arc for a rotor blade of a wind energy installation is known from PCT / EP2003 / 014621. The rotor blade has a so-called rotor blade tip which is arranged in a curved manner on the end of the rotor blade. [0003] A disadvantage of the edge arc disclosed in PCT / EP2003 / 014621 is that, as proposed, the edge arc, which can also be referred to as the rotor blade tip, consists of aluminum. The edge arcs can accordingly be heavy and expensive to produce. [0004] The terms edge arc, rotor b...
