[QUOTE="Esperluette, post: 16762063, member: 394578"] [SIZE=7][B]The stealthy little drones that fly like insects[/B][/SIZE] When Storm Ciara swept across the UK in February, Alex Caccia was strolling on Oxford's Port Meadow watching birds take to the air. He marvelled at their indifference to high winds: "While airliners were grounded by the weather the birds couldn't care less!" It was more than just a passing thought for Mr Caccia, who is the chief executive of Animal Dynamics, a technology start-up applying lessons from wildlife to drone design. Formed in 2015 to pursue the science known as biomechanics, his company already has two drones to show for an intimate study of bird and insect life. One takes inspiration from a dragonfly, and has attracted funding from the military. Its four wings make it steady in high winds that would defeat existing miniature spy drones. Known as Skeeter, the secretive project has cracked the challenge of using flapping wings to power a drone. While wings are more efficient than a propeller and allow a dragonfly to hover in the face of strong gusts they are almost impossible for human engineers to emulate.
