【摘要】 本文发展了一种对于涡轮叶片用任意圆锥曲线作为基本曲线实现几何成型的解析方法，大量试算表明，该方法可以适应相当大一部分涡轮叶片几何造型的需要．本文还用正反问题相结合的方法对实用中的涡轮叶片进行改型优化，取得了较好效果，Ｎ－Ｓ流场分析表明，改型后的新叶栅比原叶栅性能有明显改善．更多还原

【Abstract】 An analytical generating method of turbine blades was developed in this paper by using arbitrary cone curve. The proof test shows that this method is appropriate to many types of turbine blades. Two practical turbine blades in engineering were improved by combination of numerical methods for solving direct and inverse problems. The results computed with N-S equations show that the performance of the new blade cascades is much better than the original blade cascades.更多还原
