摘要
翼型是构成风力机叶片的基本要素,是风力机叶片设计的基础.发展适用于大型风力机叶片的高性能翼型,对于提高其风能捕获能力、减少重量以节约制造和运输成本、减轻惯性载荷和阵风载荷等具有重要意义.首先,回顾了上个世纪90年代以来风力机翼型族研究的发展历程,介绍了国外发展的S系列、DU系列、RIS系列、FFA系列等翼型族.其次,针对兆瓦级大型风力机翼型设计的技术要求,介绍了西北工业大学NPU-WA翼型族的设计、风洞实验及改进.最后,给出了多兆瓦级风力机翼型族的研究展望.
For a family of specially tailored airfoils, the shapes of sections along the span of the blades are the most important elements for design of wind turbine blades. The airfoils with ex- cellent performance can dramatically improve the capability of capturing wind power, reducing structural weight to save cost of manufac^ring and transportation, and lowering inertial loads as well as loads due to gust. First, the development of the main wind turbine airfoil families a- round the world since 1990＇ s was reviewed, such as S series, DU series, RIS0 series, and FFA series. Second, the progress of NPU-WA series for megawatt-size wind turbine was summa- rized, including the design process and wind-tunnel experiments. Model tests were carried out in NF-3 wind-tunnel＇ s two dimensional test section, which was the largest low-speed two di- mensional test section in Asia with the Reynolds number up to 5 millions. The further improve- ment of NPU-WA airfoils for lower roughness sensitivity was also reviewed. Last, the outlook on developing new NPU-WA series for multi-megawatt wind turbines in the near future was presented.
