| Abstract: | To solve the aircraft stealth shape design and optimization problem, a parametric modeling technique for complicated aircraft shape is proposed. Analysis of parameters impact based on orthogonal design of experiment is used to choose the design variables among excessive parameters. In order to im- prove the optimization efficiency, the surrogate model is built for RCS and aerodynamic computation. The multi-level optimization strategy is used in the stealth ＆ aerodynamic integrated optimization. In the case of a wing-body combination stealth shape design and optimization, the techniques above are verified to be feasible and effective. |
