| Abstract: | Root extending section of turbine blade is a kind of complex transition surface,of which the design process is complicated.According to geometric and structural characteristics of root extending section,a modeling method based on guide curves was provided.It initially generates guide curves by utilizing boundary conditions of root extending section,and then improves guide curves by applying minimizing energy method,finally conducts modeling of root extending section based on guide curves.This modeling method realizes the modification of area size of a cross section at a given height.The parametric design module of root extending section was developed.Therefore,the method improves the efficiency of turbine blade design,and contributes reference for parametric modeling of complicated transition surfaces of aircraft engines. |
