Microsystème à ailes vibrantes: utilisation des technologies MEMS pour la réalisation d'un microdrone bioinspiré

Abstract : This work, which is of a highly interdisciplinary nature, involves several fields such as structural dynamic, biomimicry, microfabrication technology and aerodynamic. The objective is to make progress in the design and the fabrication of a vibrating wing microsystem having an insect size by using MEMS techniques. The achievement of large wing strokes by using wing resonance and passive rotation is a concept which is developed in this thesis. Prototypes have been fabricated by using the photoresist SU-8 which presents mechanical properties close to those of insect wings. The structure was actuated and wing resonance and passive torsion have been obtained with a view to eventual flight. A more specific study concerning vibration at large displacements has been performed and a finite element model is proposed. Air wing damping is also treated to refine the model in order to discriminate between aerodynamic forces from structural forces. An experimental set-up has been developed in order to study wing kinematic and aerodynamic effects at insect size.
