Flying has been inspired by biology since the very early days of aviation. Although
aircraft look to be established with regard to their structural design today, active materials have
again triggered as to what degree aerodynamic profiles could become more adaptive with regard to
their shape and achieving enhanced flight performance. Demonstrating the shortcomings of wing
adaptiveness on manned aircraft size is time consuming and costly. This can however be overcome
by performing these demonstrations on aircraft at much smaller scale. Aircraft at this scale are
micro aerial vehicles (MAV) which have spans far less than a metre and a weight of no more than a
few hundred grams. To enhance manoeuvrability and stability birds and insects use actuation
principles along their wings such as changing wing thickness or stiffness, or actuating individual
flaps with their feathers. Similar effects will be shown for an MAV’s wing thickness and stiffness
change regarding flight stability and manoeuvrability and how this can be realised using active
materials. It will be explained how a variable V-tail and a vector thrust propulsion system can be
realised on an MAV and the resulting effect on flight performance. Results from real flight tests
will be included and conclusions will be based on the consequences regarding larger sized aircraft.
