Abstract

NURBS (Non-Uniform Rational B-Spline) is the most popular mathematical descriptor for surface modeling. To construct steam turbine blade efficiently and accurately, 2×3 NURBS was obtained to fitted blade surface as its cross-section is different tangent subsection arc and portrait is a free surface. Insert data points to unify the curve segments number of cross-section and insert the node to unity node vector, The mathematics model of blade is built with non-uniform rational B-spline and the matrix expression is given.
