Abstract

The invention relates to a rotor blade (30) of a wind turbine (100), comprising a main blade part and a blade tip (260), the blade tip (260) being detachably fastened to the main part by means of a connecting device (202). The connecting device (202) comprises a tip section (206) fastened to the blade tip (260) and a base section (204) for receiving the tip section (206), said base section being fastened to the main blade part. The tip section (206) comprises at least one securing means (242) for securing the tip section (206) to the base section (204), said securing means extending at least to the base section (204). The securing means (242) can be actuated through an opening (286) in the surface (282) of the blade tip (260) to secure the tip section.

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 manufacture. [0004] The terms edge arc, rot...
