    • The present invention is directed to a rotor blade assembly for a wind turbine. The rotor blade assembly includes a rotor blade extending from a blade root to a blade tip. The rotor blade has a pressure side surface and a suction side surface. The pressure side surface and the suction side surface each extend between a leading edge and a trailing edge. The assembly also includes a blade root extension configured to attach to one of the pressure side surface or the suction side surface of the rotor blade adjacent to the blade root. The blade root extension includes at least one blade fence and at least one airflow modifying element. The blade fence extends between a proximal end and a distal end in a chord-wise direction. The proximal end is configured to attach to the rotor blade such that the distal end remains free and spaced apart from the rotor blade. The airflow modifying element is configured at the proximal end of the blade fence. As such, the blade root extension is configured to improve aerodynamic performance of the rotor blade.
    • 本发明涉及一种用于风力涡轮机的转子叶片组件。 转子叶片组件包括从叶片根部延伸到叶片尖端的转子叶片。 转子叶片具有压力侧表面和吸力侧表面。 压力侧表面和吸力侧表面各自在前缘和后缘之间延伸。 组件还包括叶片根部延伸部,其构造成附接到与叶片根部相邻的转子叶片的压力侧表面或吸力侧表面中的一个。 叶片根部延伸部包括至少一个叶片挡板和至少一个气流修改元件。 叶片栅栏在近端和远端之间沿着弦向延伸。 近端被配置为附接到转子叶片,使得远端保持游离并与转子叶片间隔开。 气流调节元件构造在叶片栅栏的近端处。 因此,叶片根部延伸部构造成改善转子叶片的空气动力性能。
