Keywords: aeroacoustoelasticity, fluid structure interaction, active flutter control

Combined acoustic and aerodynamic loading on the structure is treated using linear superposition of the acoustic pressure disturbance to the aeroelastic problem and treatment of the acoustic pressure as motion independent and motion dependent acoustic pressure. The aerodynamic loading can also be formulated using Green’s function approach.
