A flange connection for a wind turbine, in particular a blade flange connection, having—a first flange part, in particular a blade receptacle of a rotor blade hub, a second flange part, in particular a rotor blade flange, and multiple bolts which hold the second component against the first flange part in a connected state, wherein the bolts are each screwed to the first flange part. It is proposed that the at least two bolts are in each case connected to one another by a tension means, a sensor arrangement, which detects a change in a tensile force transmitted by the tension means, being actively connected to the tension means. A wind turbine and a method for monitoring the flange connection of the wind turbine are also proposed.

A rotor blade for a rotor of a wind power installation, to a rotor for a wind power installation, to a wind power installation having a rotor blade and/or having a rotor, and to a method for connection of a rotor blade at a hub of a rotor of a wind power installation. The rotor blade comprises a hub-side end for fastening the rotor blade to a movable part of a blade bearing, wherein a bearing cover is arranged on an outer circumferential surface of the hub-side end of the rotor blade, wherein a portion of the bearing cover that is close to the bearing is further away from the outer circumferential surface of the hub-side end of the rotor blade than a portion of the bearing cover that is remote from the bearing by a multiple.
