Inspired by bats and birds,the wings of a recent type of unmanned Micro Air Vehicle can respond to air currents and change shape during flightIt flies like a bird, it was inspired by a bat and it could in every sense lift off: a recent British unmanned Micro Air Vehicle (MAV) can skim over the waves, or splash down and lift off and change wingshape in responses to the forces it encounters.
Drones enjoy been used by the military for years. But scientists based at Imperial College and Southampton University enjoy pioneered a recent approach. They are testing a recent MAV with better aerodynamic properties,which can fly long distances and will be more economical to run.
