本文研究与分析了叶型中弧线的最大弯度位置对跨音速压气机叶片气动性能的影响。采取了注重流动机理的优化方法,对本文算例的风扇叶片进行了优化,改进后所得的叶片的效率比原设计有了较大的提高。

Effect of the maximum camber location on the aerodynamic performance of transonic compressor blading was studied by numerical method. As an example of the research, a transonic compressor blading was studied and optimized. The optimization methodology is based on flow mechanism understanding. The adiabatic efficiency of the compressor was increased compared with the original design.
