Automated construction of a parametric model of the fan blade

Abstract

 The geometrical parameters necessary for creation of parametric model of a fan blade are chosen. A parametric 3D model of the fan blade has been developed. A program for modeling parametric 3D models of fan blades has been created. The principle of automated creation of parametric model of the fan blade in the CAD-system Siemens NX based on the results of control and measurement activities is presented. The obtained models can significantly reduce the time for preparation and carrying out mechanical integrity and aerodynamic calculations, and is an important step in the complex of measures for multidisciplinary robust optimization of the fan blades.
