【摘要】 本文通过研制弯扭叶片成型程序,阐述了燃气透平弯扭静叶的设计方法,分析了叶片各种弯曲方法对燃气透平性能的影响;证实了采用弯扭叶片能改善透平叶栅流动状况、减少损失的理论;最后用Auto CAD微机绘图软件绘出了造型后叶片的平面及空间轴侧图形。更多还原

【Abstract】 This paper proposed a design method for bowing and twisting blade in gas turbine; analyzed the effects of various bowing methods on the proformance of gas turbine and proved that this kind of blade can improve the flow condition in cascade of turbine and reduce losses. At last, with the use of Auto CAD soft ware, the 3-D drawings of the designed blade were plotted .更多还原
