Summary:The invention discloses an empirical formula blade generation system, which is characterized in that subsonic and transonic turbine stages are designed, and values of design variables used in a parameterization system are calculated by correlation equations; the design variables need to be modified through iteration; then generating geometric shapes and blocks of the stator and the rotor by a parameterization system; automatically forming a grid through an ICEM CFD script by using geometric figures and blocks; the performance of the turbine stage is evaluated through a CFD solver; a calculation result is analyzed, and a future improvement direction is found; and the final blade design is obtained through multiple rounds of repeated training and residual iteration. Finally, high efficiency subsonic and transonic turbine stages are produced. 本发明公开了一种经验公式叶片生成系统,设计亚音速和跨音速涡轮级,参数化系统中使用的设计变量的值由相关方程计算;需要迭代来修改设计变量;然后由参数化系统生成静子和转子的几何形状和块;通过使用几何图形和块,在经ICEM CFD脚本自动形成网格;之后通过CFD求解器评估涡轮级的性能;对计算结果进行分析,并寻找未来改进的方向;通过多轮反复训练和残差迭
