It is widely thought that wing flexibility and wing deformation could significantly affect aerodynamic force productions over completely rigid wings in flapping motion. However, there is a lack of quantitative discussion of dynamic formation of wing camber and its effect on wing's aerodynamic performance. In this work, 2D deformable plates with three adjustable parameters are used to model the wing camber and its dynamic formation. A Direct Numerical Simulation (DNS) based computational optimization frame has been developed to obtain the optimal setting of those parameters for maximizing the mean lift coefficient. Results have shown more than one local maximums are obtained from the optimization process. Force production and its unsteady flows are also discussed for the better performed plate.
