关于采用复合型线的圆柱型叶片的研究

Research into Combined Contour of Cylindrical Blade

本文作者介绍了以两种不同类型的曲线合成圆柱形叶片型线新方法 ,这种复合曲线的包角值和安放角具有较为理想的分布规律 。

This paper presented a new method to form contour of cylindrical blades by employing two types of curves,the wrapping angle and vane setting angle distribution of the combined curve,which have many advantages over the traditional ones The hydraulic features of the cylindrical blades will thus be improved
