 How to eliminate flutter in flow structure interactions.

An appearance of utter in oscillating structures is an endemic phenomenon. Most common causes are vibrations induced by the moving flow of a gas which is interacting with the structure. Typical examples include: turbulent jets, vibrating bridges, oscillating facial palate in the onset of apnea. In the case of an aircraft it may compromise its safety. The intensity of the flutter depends heavily on the speed of the flow (subsonic, transonic or supersonic regimes). Thus, reduction or attenuation of flutter is one of the key problems in aeroelasticity with application to a variety of elds including aerospace engineering, structural engineering, medicine and life sciences. Mathematical models describing this phenomenon involve coupled systems of artial di erential equations (Euler Equation and nonlinear plate equation) with interaction at the interface - which is the boundary surface of the structure. The aim of this talk is to present a theory describing: (1) qualitative properties of the resulting dynamical systems (existence, uniqueness and robustness of nite energy solutions), (2) asymptotic stability and associated long time behavior that includes the study of global attractors, (3) feedback control strategies aiming at the elimination or attenuation of the flutter. As a consequence one concludes that the flow alone (without any dissipation added to the elastic structure) provides some stabilizing e ffect on the plate by reducing asymptotically its dynamics to a nite dimensional structure. However, the resulting "dynamical system" may be exhibiting a chaotic behavior. In the subsonic case, one also shows that the flutter can be eliminated by adding structural damping to the plate.
