The turbine airfoil design process is very complex and time-consuming, and it requires skilled aero/thermo designers to achieve the optimum balance between efficiency requirements, mechanical reliability, and manufacturing cost.This paper describes the use of an integrated, multidisciplinary, multi-objective optimization system for the aerodynamic and mechanical design of turbine blades.Process integration and design optimization software is used to link together commercially available simulation codes to automate airfoil shape generation, CFD analysis, stress and vibration analysis, and post-processing of results.Expert design rules and constraints are captured in the system, and various optimization strategies are employed to automatically search the design space to find optimal designs that meet goals for performance and stresses.The system produces substantial reductions in design cycle time, and it can be used to assess the trade-offs between multiple objectives.
