Abstract

Conventional design of micro-aerial vehicles (MAVs) uses fixed airframe design optimized for the entire flight path. This compromise leads to sub-optimal flight characteristics during certain flight regimes. Birds’ wings show great versatility during various stages of flight using feathers and wrist joints. A new design is proposed using piezoelectric patches known as macro-fiber composite (MFC) embedded directly on the surface of the wing and tail to serve as control actuators. In addition, sweeping mechanism was developed to mimic the folding action of birds for a stable dive maneuver. The use of MFCs and sweeping mechanism for controlling MAVs presents a unique challenge for optimizing the effectiveness of these actuators for all flight maneuvers. Numerical models were developed using structural and aerodynamic tools to optimize the location of the MFCs for maximum deflection and overall aerodynamic performance. Digital image correlation (DIC) was used to validate the full field deformation of the control surfaces under simulated aerodynamic loading.
