Lean aero-elasticity design and verification technology system were established in AVIC Chengdu Aircraft Design and Research Institute according to the project development requirements and task particularity. Critical technology research and optimization design and analysis aiming at enhancing aircraft aero-elastic quality were carried out based on multi-disciplinary design optimization process. Whole aircraft dynamic characteristics ground test with consideration of all-movable surface structural nonlinearity, subsonic/transonic/supersonic flutter model wind tunnel tests that cover all Mach numbers and flight aero-elasticity test verification were completed and passed. Aero-elasticity design objective was achieved within a short development period, providing technical support for successful development of new-generation fighter. This paper describes the design process, major technical work of the aircraft, as well as the gained technical progress, capability enhancement, and knowledge engineering construction of aeroelastic design with research institute characteristics.
