Development of Optimization Design system for Aero-engine Turbine Stator

Based on ANSYS- a large finite element analysis software for calculate and analysis platform, a system developed for the design optimization of turbine stators. This system puts classical intension calculate method, finite element numerical calculate method in engine and modern design technology together, and developed a structure optimization platform for the component of turbine stators. A whole new optimization method of geometry model-> numerical value parameterize ->finite element analysis->GAS optimization is made through the combine of the CAD parametric model technology and the CAE analysis technology. In this paper, the hole shape optimization of the turbine stator component is considered as a typical example of practical applications. Computing results show that the proposed system is a powerful design tools for the rapid optimization of specific engineering structures.
