- Abstract
- A new method is presented for an ef cient inverse design of transonic wings with minimum drag and weight. To this end, the target pressure optimizationmethod is extended for a simultaneous design of wing planform and target pressures so that an inverse design can be conducted with the optimized planform and section target pressures. During the optimization procedure, the maximum thickness of wing sections and spanwise lift distribution should be predicted without any ow analysis, and response surfaces are, therefore, constructed for this purpose. Sample data points for the response surfaces are selected from the D-optimality and calculated by a thin-layer Navier–Stokes code. For the optimization problem, a genetic algorithm is adopted. Design examples show that the present design method gives successful results with the computational cost reduced by one order of magnitude compared to a direct response surface construction for lift and drag coef cients.
