A CRANFIELD UNIVERSITY team is developing flapping wings powered by piezoelectric motors for future military surveillance micro-planes.
Piezoelectric-controlled wings could better mimic an insect's complex wing motion - the holy grail of flapping-wing flight researchers. Piezoelectric crystals change shape by a small amount when a voltage is applied.
The team claimed that the military is likely to be interested in the results of the project because highly manoeuvrable micro-air vehicles (MAVs) could one day be used for surveillance using flapping-wing propulsion. The US has invested heavily in flapping-wing technology in the past decade, and MoD ...
