具有后缘突部的风力涡轮机的叶片
摘要：
一种风力涡轮机的叶片(20B至20C)，该叶片(20B至20C)具有圆角化的后缘(42A至42E)和长形的突部(44A至44J)，突部(44A至44J)在当地弦(C)的后10％内从压力侧(PS)延伸并且与后缘大致平行以增大升力。突部可以具有高度(H)，该高度(H)在径向内侧端最大以使升力最大化，并且在外侧端减小以使阻力最小化。突部可以具有长度为突部高度的至少60％的基部。
摘要（英）：

A wind turbine blade (20B-C) with a rounded trailing edge (42A-E) and an elongated tab (44A-J) extending from the pressure side (PS) within the aft 10% of the local chord (C) and generally parallel to the trailing edge to increase lift. The tab may have a height (H) that is greatest on the radially inboard end to maximize lift, and lower on the outboard end to minimize drag. It may have a base with a length of at least 60% of its height.
