On the basis of analyzing the theory of the modeling of the propeller surface, this paper transforms the section data given by design to the data in Descartes coordinates. Interpolates the section data to get enough data and fits the blade surface with the least square method. A perfect C2 blade surface can be obtained by adjusting the deviation weight and fairing weight. According to the cylinder rough, two rough cut methods are preferred.

本论文在深入分析螺旋桨曲面成型原理的基础上，将设计时给定的桨叶曲面的切面数据转化为笛卡尔坐标系中的坐标，利用B样条方法对截面数据点插值并加密，得到足够的数据点，进而利用最小二乘法拟合出桨叶曲面，通过调整偏离权和光顺权得到了理想的二阶连续的桨叶曲面。
