| Abstract: | In this paper, a joined-wing wind tunnel model with high aspect ration was taken as an example for optimization design. CFD-FEM iteration with positive and reverse design was carried out, making use of CFD software based on Euler method and FEM software based on linear structure analysis. Aerodynamic optimization took into account static aeroekastics of wind tunnel model. Results of wind tunnel test validated the design scheme. And the lift-to-drag ratio was improved by 10% at the design point. |
