Multi-Objective Aerodynamic Optimization of Supercritical Wing with a Large Number of Constraints

摘要：

　　A multi-objective aerodynamic optimization of supercritical wing of a wide-body aircraft based on genetic algorithm and CST parameterization method is presented in this paper.Favorable pressure distributions of a “supercritical type wing are considered as a lot of constraints in the optimization process.Geometry constraints and aerodynamic constraints are also employed.A full potential solver is adopted as a low fidelity aerodynamic analysis tool for preliminary optimization.A Reynolds Averaged Navier-Stokes solver is used as high fidelity tool for detailed optimization,and design validation.With more than 150 constraints,the optimized design has a typical supercritical pressure distribution.The CFD results also show that the design has a superior aerodynamic performance.
