Bird wings inspire new approach to flight safety

Taking inspiration from bird feathers, Princeton engineers have found that adding rows of flaps to a remote-controlled aircraft’s wings improves flight performance and helps prevent stalling, a condition that can jeopardize a plane’s ability to stay aloft.

NicholsGirguis Sedky, postdoctoral researcher and the paper’s lead author, called the technique “an easy and cost-effective way to drastically improve flight performance without additional power requirements.” The team attached the covert-inspired flaps to a 3D-printed model airplane wing and mounted it in the wind tunnel, a 30-foot-tall metal contraption that simulates and measures air flow.
