Scientists have designed a micro aircraft that will be able to flap, glide and hover like a bird.
Researchers from the Biomimetics-Innovation-Centre in Germany have been inspired by birds to produce a new versatile design of Micro air vehicle (MAV) that combines flapping wings, which allow it to fly at slow speeds and hover, with the ability to glide, ensuring good quality images from any on-board camera.
"In birds, the combination of demanding tasks like take-off, traveling long distances, maneuvering in confined areas and landing is daily practice," explains PhD researcher Mr. William Thielicke, who is presenting this work at the Society for Experimental Biology Annual Conference in Glasgow on the 2nd of July.
This innovative design was inspired by one bird in particular, the swift. "We know that swifts are very maneuverable and they can glide very efficiently. So we thought these birds would be a very good starting point for an energy efficient flapping-wing MAV," says Mr. Thielicke.
While fixed wing MAVs are energy efficient, their maneuverability is low. The new design would allow the flapping wing MAV to glide, improving energy efficiency and ensuring good images but when needed it can also slow its flight and maneuver in confined spaces.
"Although the models are not yet ready to be used, initial tests are positive and we hope that this design will combine the best of both worlds," says Mr. Thielicke.
