Abstract:
Emergence of flutter compromises not only the long-term durability of the wing
structure, but also the operational safety, flight performance and energy
efficiency of the aircraft. Effectual means of flutter prevention are,
therefore, mandatory in the certification of new flight vehicles. This work
intends to address the flutter phenomenon highlighting the above issues, and
reviews some of the most recent theoretical and experimental developments in
flutter analyses. In the following subsections, theoretical, computational and
experimental flutter for composite structures is pursued. In particular, panel
flutter, thrust-induced flutter, wing/store-type flutter, non-linear flutter,
damaged panel flutter, flutter in compressed flow and flutter control via neural
networks are covered. Effects of fibre/ply orientation on flutter are also
briefly covered. The review further looks into aerothermoelastic behaviour of
composite structures buckling problem and hopf bifurcation point determination.
Analysed flutter of actively/passively controlled composite structures is
critically reviewed due to the emphasized importance in modern structures. It is
appreciable that the knowledge gained from the study of flexible structures and
unsteady airflows in aircraft can be transitioned back to more traditional
flutter studies. It is hoped that this review work will stimulate research and
collaborations that will lead to significant progress in the understanding of
this dynamically rich and potentially important area of enhancement of flutter
prediction, suppression and control of active and passive composite aircraft
structures. Copyright (C) 2006 John Wiley & Sons, Ltd.
