摘要
基于非均匀有理B样条(NURBS)曲线及节点插入算法,提出了一种汽轮机二维叶型参数化设计方法。同时,兼顾设计参数的实际物理意义和型线调节的灵活性,解决叶片前缘关键点处曲率连续性的问题。据此,结合Visual C++2008与OpenGL开发汽轮机叶片设计软件,完成叶型的参数化设计,并对该设计方法的可行性进行了验证。
On the basis of non uniform rational B spline curve(NURBS) and knot insertion algorithm,a turbine blade parametric design method with two dimension was presented.Moreover,actual physical meaning of the design parameters and flexibility of the profile regulation were both taken into account to solve the front key point curvature continuity problems.Thus,combining with the Visual C++ 2008 and the Open Graphics Library,a turbine blade design software was developed to complete the blade parametric design and verify the feasibility of design method.
