It is important to begin aeroelastic design studies in the preliminary design phase. Structural optimization programs are very helpful in analysing and solving aeroelastic problems on aircraft components. Using fiber composites, a new design technique called 'aeroelastic tailoring' provides new capabilities in fullfilling stiffness requirements for aerodynamic surfaces. Benefits of aeroelastic tailoring are shown on a fighter fin design. Design of advanced digital flight control systems needs a good knowledge of the elastic aircraft behavior such as elastic derivatives and control surface effectiveness. Structural computer models of a total aircraft can be built up according to the actual development phase, without loosing transparency because of the complexity of large finite element models. Test-to-analysis comparisons are necessary in aerodynamics, structures and structural dynamics to up-date computer models and to find out shortcomings of analyses.
