Researchers from Brown University developed a new wing design for small drones that’s inspired by the wings of birds and insects. The new wing allows small drones to fly more efficiently and makes them more “robust to atmospheric turbulence.” The bio-inspired wing, dubbed as the “Separated Flow Airfoil,” reduces the effects of turbulence and improves flight efficiency. The wing is designed to separate the flow of air at the leading edge. The flow is then reattached to the airfoil with the help of a small rounded flap located on the wing’s trailing edge. The airfoil allows for a more efficient and stable flight for drones with wingspans of one foot or less.
