Abstract:
Piezoelectric fans consisting of a piezoelectric layer and an elastic metal
layer were prepared by epoxy bonding and a coupled flexible wing was formed by a
pair of carbon fibre reinforced plastic wing spars and polymer skin attached to
two piezoelectric fans. Two sinusoidal voltages with phase differences were then
used to drive the coupled piezoelectric fans. High speed digital cameras were
used to characterize the two degree of freedom (DOF) motion of the wing and
these results were compared to finite element model of the wing and the coupled
piezoelectric fans. It has been observed that the phase delay between the
driving voltages applied to the coupled piezoelectric fans plays an important
role in the control of the flapping and twisting motions of the wing and this
set-up has the potential for application to the control of flapping wings for
micro aerial vehicles. (c) 2008 Elsevier B.V. All rights reserved.
