Keywords: MDO, Variable-Fidelity, NURBS, engine-airframe integration

To use MDO as a practical design tool of an aircraft, the CAD based geometric representation method and the variable-fidelity evaluation method were introduced. As a result, the optimum wing geometry with structural constraints could be obtained from a large design space in the practical time.
