Abstract: Recent advances in structure technology have stimulated various new aircraft configurations, such as a flying wing aircraft for stealth purpose, a solar aircraft with extremely high span-chord ratio for energy saving, and a morphing aircraft for multiple flight missions. Those new aircraft feature very flexible structures and give rise to tough problems of dynamics and control, including nonlinear flutters and their active suppressions. This lecture presents how to model a flexible aircraft and to predict its nonlinear flutter in a frame of multi-body system dynamics and unsteady aerodynamics first. Then, it demonstrates how to simplify the high dimensional model of an aero-elastic problem for flutter control via data-driven techniques embedded with mechanics knowledge. Afterwards, the lecture deals with the body-freedom flutter control of a flying wing aircraft. Finally, it outlines some open problems in aero-servo-elasticity.
