Ahmed K. Othman, Girguis Sedky, Hannah Wiswell and Aimy Wissa (left to right) equipped the wings of an RC plane with covert-inspired flaps, and flew it at Princeton's Forrestal Campus to prove that ...

Discover how Princeton engineers used bird feathers' tricks to create self-recovering wings, enhancing lift and stability ...

Postdoctoral researcher Girguis O. Sedky sitting inside of the wind tunnel, showing the covert feather-inspired flaps attached to the 3D-printed model airplane wing. The flaps deploy automatically in ...

Airbus is moving ahead with its vision of aircraft with active wing control, following successful wind tunnel tests at its facility near Bristol, England. The company is working to mimic the behavior ...

Bird physiology is conducive to flight: small size, hollow bones, and generally symmetrical feathers on the wings and tail. It seems like a no-brainer that bird evolution was optimized for flight, but ...

Engineers found a way to help airplanes avoid stall with lightweight plastic flaps that flutter with pressure changes. The flaps mimick a class of feathers that are key to birds' most daring aerial ...
