Abstract

A micro air vehicle that can achieve a versatile flight condition is being designed. One way of achieving such versatility is through biomimicry. One aspect of this design utilizes a bird-like wing that changes shape to match four flight regimes; take-off-and -landing, cruise, high speed dash and one that enhances maneuverability. A joint mechanism using a tendon actuator between the inboard and the outboard portions of the wing is used to modify wing sweep. Macro fiber composites (MFCs) piezoelectric actuators in a bi-morph configuration are incorporated into the MAVs as control mechanism. Camber changes are implemented with tendon actuators. Finite element is used to model the wing section and perform a full-field deformation study and compared with experimental results. Digital image correlation is used to validate the wing deformations predicted by finite element method (FEA).
