To improve design quality and efficiency of turbine blade, the geometric model of blade is parameterized by using the quintic polynomial method in this paper. The geometric shape and performance of blade mainly depend on blade profile and cascade with parametric model. First of all, the blade profile lines are designed and generated in different parameters based on the theory of quintic polynomial. The effect of relative parameters on the blade profile is analysed conveniently and rapidly. Then, the geometric shape of blade is generated in the arranged blade profiles according to blade cascade position and consistency. The 3D model of blade is created by the parametric blade profile and cascade. It is shown that parametric model of blade will provide the reference and foundation for application research.
