Abstract

For the needs of freeform surface like impeller and blade, this paper takes the Non-Uniform B_Spline as a mathematical model, the programs are implemented in the integrated development environment Delphi 5.0, the error of B-Spline is analyzed, and the error distribution graph is drawing clearly, finally impeller and blade surface modeling is complenmented using B_Spline.
