Abstract: The paper describes recent developments in the United States in the application of structural optimization techniques to problems of design under aeroelastic constraints. In particular, the following topics are discussed: (i) conventional-strength design using aeroelastically calculated loads; (ii) aeroelastic tailoring for improved performance; (iii) design under flutter and static aeroelastic constraints; and (iv) miscellaneous applications. Because of the high cost of applying formal optimization techniques to practical design problems, there have been very few applications of structural optimizations to actual aircraft. The paper is focused on trends that may eventually reverse this situation.

Keywords: aeroelastic constraints; aeroelastic tailoring; aircraft design; aircraft structures; composite materials; divergence constraints; finite element analysis; flutter constraints; optimisation techniques; strength design; structural optimisation; USA; United States.
