A rotor assembly is provided that includes a hub rotatable about an axis of rotation. The assembly also includes a plurality of rotor blades spaced circumferentially about the hub. Each of said rotor blades extends from a blade root to a blade tip such that said plurality of blades are rotatable through a plane of rotation extending about said axis of rotation, said plane of rotation is defined as substantially perpendicular to said axis of rotation, wherein each of said blade roots is coupled to said hub, wherein each of said blade tips is offset a distance upstream from said plane of rotation.

Rotor assembly for a wind turbine and method of assembling the same

A method for monitoring a wind turbine. A monitoring signal, including an audio signal and/or an image signal, is received from a monitoring device. Operating data are calculated based on the received monitoring signal. An operating condition and/or a deviation is determined by comparing the operating data to baseline data.

System, device, and method for acoustic and visual monitoring of a wind turbine

A rotor blade for a wind turbine is provided, wherein the rotor blade has radial bores in a wall of a blade root portion, the radial bores being staggered in a longitudinal direction of the rotor blade, and longitudinal bores in the wall of the blade root portion, wherein each of the longitudinal bores extends from a blade flange to a corresponding radial bore.
