    • A wind turbine rotor blade assembly includes a rotor blade having a pressure side, a suction side, a leading edge, and a trailing edge extending in a generally span-wise direction between a tip and a root. An edge extension is attached along either or both of the leading edge or trailing edge in a generally span-wise direction from adjacent the root towards the blade tip, with the edge extension having a contoured outer surface that defines a generally continuous aerodynamic surface. The edge extension has a terminal end that is spaced from root. A curtain is attached to the edge extension and extends in a span-wise direction from the terminal end t to the root. The curtain is formed from a pliant, flexible material that accommodates connection of the root to a rotor hub, as well as pitch movement of the rotor blade relative to the hub.
    • 风力涡轮机转子叶片组件包括具有压力侧,吸力侧,前缘和在尖端和根部之间沿大致跨度方向延伸的后缘的转子叶片。 边缘延伸部沿着从邻近根部朝向叶片尖端的大致跨度方向的前缘或后缘中的一个或两侧附接,边缘延伸部具有限定大致连续的空气动力学表面的轮廓外表面。 边缘延伸部具有与根部分开的末端。 帘幕附着在边缘延伸部分上,并沿着从终端t到根部的跨度方向延伸。 窗帘由柔性材料制成,其适应根部与转子毂的连接,以及转子叶片相对于轮毂的俯仰移动。
