摘要(Abstract)：

为了提高离心压缩机的气体动力性能,设计了从轮盘到轮盖侧叶片出口角变化规律不同的多种三元叶轮级,通过试验对母型三元叶轮级及由母型级得到的派生三元叶轮级的性能进行了研究,取得了令人满意的结果。
In order to improve the aerodynamic performance of centrifugal compressor, various three dimentional stages were designed with the changes of vaned exit angle from hub to shroud blades. Satisfactory result is obtained by means of experimental study on the performance of the prototype stage with derived stages of centrifugal compressor.
