摘要
通过小展弦比透平矩形静叶栅的低速风洞实验,研究了在不同冲角下栅后有无尾板叶片弯曲对叶栅气动特性改善作用的区别,实验结果表明,叶栅出口条件是影响叶片弯曲效果的重要因素之一。
By the experiments in a low speed wind runnel for turbine rectangular stator cascades equipped and unequipped with the tailgate with a small aspect at different incidence, the influence of the tailgate on the improvement effect of the cascade aerodynamic characteristics is studied. The experimental results show that the cascade exit condition is one of the important factors influencing on the effect of blade curving.
