风力机组叶片的先进翼型族设计

摘要

大型风力机组叶片设计需要专用的翼型族,以满足风力机组运行的环境要求.高升阻比、低粗糙度影响是该翼型族的气动性能特点.为了发展我国具有自主知识产权的风力机专用翼型族,在科技部863项目的支持下,北京航空航天大学联合国内气动研究单位,通过理论分析、数值模拟和风洞试验等技术途径,开发了两个适用于大型风力机组叶片的先进翼型族.理论分析和风洞试验表明,设计结果基本达到了预先设定的气动性能指标.%Due to the tough condition in which the wind turbine is running, the airfoils used to design blade need to be specially designed. We should pay more attention to the aerodynamic properties as high lift, low drag and insensitive to surface roughness. Soupported under the "863" project (2007AA05Z449), two airfoil families have been designed specially for large-scale wind turbine blades through analysis, numerical simulation and wind tunnel test in BeiHang University. Experimental results show the design is successful.
