Flapping micro air vehicles inspired by swifts

This innovative design was inspired by one bird in particular, the swift. "We know that swifts are very manoeuvrable 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 manoeuvrability 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 manoeuvre 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.

This shows the wake of a swift in slow forward flight, the new design mimics these birds to improve MAV performance.

Micro air vehicles (MAVs) are small unmanned aircraft, often used for rescue or reconnaissance missions in areas where it would be dangerous or impractical for humans to go.
