Changsheng Jiang · Aircraft Design · 2008
The paper presented here demonstrates the application of particle swarm optimization(PSO)on lift-to-drag ratio optimization design of laminar airfoil.Designed airfoil is successful to meet the design requirement and optimized airfoils have a considerable improvement on aerodynamic performance,show the feasibility of particle swarm optimization applied on aerodynamic optimization design.During the course of aerodynamic optimization design,particles use descending inertial power for enhance full area search capability at earlier and part area search capability at anaphase.Geometric shape of airfoil is represented by linear combination of analytical functions,and objective function and fitness of every individual are provided by flow solver of two-dimensional Euler equations.
