Flutter prediction, suppression and control in aircraft composite wings as a design prerequisite: a survey

摘要

Emergence of flutter compromises not only the long-term durability of the wingstructure, but also the operational safety, flight performance and energyefficiency of the aircraft. Effectual means of flutter prevention are,therefore, mandatory in the certification of new flight vehicles. This workintends to address the flutter phenomenon highlighting the above issues, andreviews some of the most recent theoretical and experimental developments influtter analyses. In the following subsections, theoretical, computational andexperimental flutter for composite structures is pursued. In particular, panelflutter, thrust-induced flutter, wing/store-type flutter, non-linear flutter,damaged panel flutter, flutter in compressed flow and flutter control via neuralnetworks are covered. Effects of fibre/ply orientation on flutter are alsobriefly covered. The review further looks into aerothermoelastic behaviour ofcomposite structures buckling problem and hopf bifurcation point determination.Analysed flutter of actively/passively controlled composite structures iscritically reviewed due to the emphasized importance in modern structures. It isappreciable that the knowledge gained from the study of flexible structures andunsteady airflows in aircraft can be transitioned back to more traditionalflutter studies. It is hoped that this review work will stimulate research andcollaborations that will lead to significant progress in the understanding ofthis dynamically rich and potentially important area of enhancement of flutterprediction, suppression and control of active and passive composite aircraftstructures.
