给出了轴流风机薄板叶型的三种解析设计方法，并对所设计叶型的气动性能作了比较。结果表明：型面曲率连续的叶型的气动性能是基本相同的；双圆弧叶型容易出现分离流动；单圆弧叶型气动性能可以代表具有连续曲率的一族叶型的气动性能。它构造方法简单，适用于薄板叶型设计。

Three different analytical thin blade design methods are presented together with their aerodynamic performance comparison. Results show that blades of continuous curvature along the profile achieve nearly the same aero-performance. One circle blade can represent one family of continuous curvature profile by performance, and is easy...
