摘要

#CMT# #/CMT# The plant (10) has a rotor (20) comprising a rotatably supported rotor blade (26), and a collecting device for collecting air. A guiding device is arranged at the rotor blade, and stays in effective fluid connection with the collecting device, where the air is guided along the rotor blade through the guiding device. The collecting device is connected with the rotor in a torque-proof manner, where an axis of the collecting device is oriented parallel and coaxial to a rotational axis (21) of the rotor. A channel device stays in effective fluid connection with the collecting device. #CMT# : #/CMT# An independent claim is also included for a method for operating a wind power plant. #CMT#USE : #/CMT# Wind power plant for generating electrical energy from wind. #CMT#ADVANTAGE : #/CMT# The guiding device is arranged at the rotor blade, and stays in effective fluid connection with the collecting device, where the air is guided along the rotor blade through the guiding device, thus reducing wall friction in the rotor, reducing material loading at the rotor blade and increasing efficiency of the power plant even during reduced wind speed. The collecting device is connected with the rotor in a torque-proof manner, thus achieving distribution of air stream on the rotor blade in a simple manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side view of a wind power plant. 10 : Wind power plant 16 : Holding device 20 : Rotor 21 : Rotational axis 26 : Rotatably supported rotor blade.
