Active flutter suppression, which is a part of the group of flight vehicle technologies known as
active controls, is an important contributor to the effective solution of aeroelastic instability …

Current economic constraints and environmental regulations call for design of more efficient
aircraft configurations. An observed trend in aircraft design to reduce the lift induced drag …

Flutter is a dynamic aeroelastic instability driven by the interaction of inertial, elastic, and
aerodynamic forces. It is an undesirable phenomenon in aircraft because it causes divergent …

The unsteady vortex-lattice method provides a medium-fidelity tool for the prediction of non-
stationary aerodynamic loads in low-speed, but high-Reynolds-number, attached flow …

The stability boundaries of a very flexible wing are sought to inform a wind-tunnel flutter test
campaign. The objective is twofold: to identify via simulation the relevant physical processes …
