Parametric Modeling System for Cooling Turbine Blade Based on Feature Design

Based on feature modeling and mathematical analysis methods, a process-oriented and modular parametric design system for advanced turbine cooling blade is developed with UG API, aiming at the structural complexity and high design difficulty of aero-engine cooling turbine blade. The relationship between the external and internal body features, the body attached feature is analyzed as viewed from the feature and parameter terms. The parametric design processes and design examples of the external body shape, tenon, platform and internal body shape, ribs, pin fins are introduced. The system improves the design efficiency of cooling turbine blade and establishes the foundation of multidisciplinary design optimization procedure for it.
