摘　　要：为了对具有“后部加载”叶型叶栅的气动性能进行深入的了解 ,本文在环形叶栅低速风洞上对具有“后部加载”叶型的常规直叶片栅和弯叶片栅进行了吹风实验。实验结果表明 :采用先进的“后部加载”For understanding the aerodynamic characteristics of the blade cascade with aft-loading profiles, the experimental investigations were carried out on the low speed annular wind tunnel with the conventional straight blades and the curved blades cascades that have the aft-loading profiles. The experimental results show that it would highly improvement the vane's performance by using the advanced aft-loading profiles and the curved blades.
