Supercritical Wing Aerodynamic Optimization Based on Multi-Strategy Method

A new method was applied to the wing aerodynamic optimization design based on the research of optimization strategy.The Hicks_Henne function for generating geometric disturbance was used to modify the sections of the initial wing.A better shape was given in cruise points after multiple iterations using GA-PSO method.The design results indicate the final wing compared with the initial wing,effectively improves the cruise efficiency with better aerodynamic performance and can also better meet the requirements of the drag divergence Mach number.
