摘　　要：在分析螺旋桨桨叶型面特征的基础上,利用VC和UG的二次开发工具UG OPEN GRIP编制了螺旋桨三维数字化模型的建模系统。该系统可根据螺旋桨几个基本特征参数进行参数化建模。桨叶曲面为非均匀有理B-样条曲面,达到了桨叶曲面的精度要求。On the basis of the analysis of surface characteristics for propeller blade, has established modeling system of three dimensional digitization model for propeller by make use of VC and UG OPEN GRIP of UG re-development tool. This system may carry on the parametric modeling according to several basic characteristic parameters of the propeller. The surface of the paddle blade is non-uniform rational B-spline surface, the surface has met precision requirements for paddle blade.
