摘要 针对兆瓦级大型风力机,研究发展了以具有更优良高雷诺数和高升力气动性能为特点的NPU-WA翼型族,风洞实验表明,该翼型族达到了在高雷诺数、高升力条件下实现高升阻比和外侧翼型对粗糙度不敏感的主要设计要求,为我国自主研发大型风力机提供了可以实际使用的翼型几何数据和雷诺数范围内1.0×106~5.0×106的风洞实验数据。 NPU-WA airfoil family is designed for MW-size wind turbines and it is featured by advanced aerodynamic performance at high lift and high Reynolds number. Wind tunnel tests show that the airfoils are of higher lift to drag ratio than present wind turbine airfoils at high lift and high Reynolds number and insensitivity of maximum lift to leading edge roughness, which are satisfied the main design requirements. From this study the NPU-WA airfoil data base including geometry and the wind tunnel test performance at Reynolds number from 1.0 X 106-5.0)〈 10^6 are developed. The airfoils can be applied to MW-size wind tur bine design for the China industry with independent intellectual property rights.
