Abstract
In this paper, Multidisciplinary Design Optimization (MDO) system for practical aircraft design is developed. The MDO system is based on the integration of low and high fidelity computational fluid dynamics (CFD) codes into the NASTRAN based structural/aeroelastic codes. Multi-Objective Genetic Algorithm (MOGA) based on Kriging model is employed as an optimizer to reduce the computational cost. As a result of optimization, several non-dominated solutions, indicating the trade-off among the cruise drag, the structural weight, the drag divergence and the pitching moment, have been generated.
