It realized anticipated goals of the application of turbine blade and engineering exercises. Thus, it provide the foundation to the reconstruct and optimize design of turbine blade as well as the CAM of turbine blade.

• 算例结果表明，上述方法不仅可精确拟合混流式、轴流式水轮机转轮叶片，而且还能对叶片进行求交、延展运算并控制精度，实现了Nurbs曲面造型技术应用于水轮机叶片设计和工程实际的预期目标，为水轮机叶片的改型设计和优化设计、水轮机叶片的计算机辅助制造打下了基础。
