The paper is devoted to development of methodologies of fast preliminary aircraft design by using multidisciplinary analysis and optimization at satisfying strength and aeroelasticity requirements. Two-level approach is proposed for design of composite/metallic wing. Comparison of aeroelasticity analysis characteristics with results of TsAGI wind tunnel tests is presented.
