摘　　要：本文基于完全径向平衡方程,研究发展了一套多级轴流透平多截面气动设计方法和叶片造型方法。采用该方法对某型燃气轮机四级透平进行了气动设计,并对设计出的透平进行了三维定常流场计算,结果表明,三维计算结果与设计结果吻合较好。Based on the full radial- equilibrium equation, a multi -section aerodynamic design method and a 3D blading method for multi - stage axial - flow turbine were developed. The aerodynamic design for a four - stage axial - flow turbine was carried out by using the present methods and the 3D flow in the designed turbine was computed by using a 3D steady RANS solver. The results show that the aerodynamic design results agree well with the 3D computational results.
