An advanced aeroelastic model (plate/box beam) of delaminated aircraft structure will be developed using unified theory. The flutter analysis and control of the structure will also be performed under hygrothermal environment. The Gust response analysis of delaminated structure will also be performed. AFC will be used as sensor and actuator to control the aeroelastic response of damage structure. The studies also includes optimal placement of sensor and actuator and use of various control analysis.Finally, a modal analysis of delaminated plate will be performed to model upgraded of aeroelastic structure.
