轴流风机薄板叶型设计方法的比较

给出了轴流风机薄板叶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：型曲面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；单圆弧叶型所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。

Comparison of Thin Blade Design Method for Axial Fans

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 and effective for thin blade designing.
