Abstract

The aeroelastic flutter is an undamped oscillation that occurs on flexible structures placed into an airflow. It is caused by the interaction of the structural dynamics and the aerodynamics. Since it generally leads to structural failure, it has to be avoided. The paper proposes a complete framework for handling the aeroservoelastic behavior of aerospace applications, addressing the high dimensional problem in a tractable manner. The applicability of the proposed methodology is demonstrated by designing a flutter suppression controller for the BAH jet transport wing.
