Researchers at the Engineering School at Princeton University have taken inspiration from birds to improve flight performance and safety in aircraft. The researchers deployed rows of flaps to the wing ...

Birds have long been our inspiration for flight, and researchers at Princeton University have found a new trick in their arsenal: covert feathers. These small feathers on top of birds’ wings lay flat ...

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 ...

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 ...

Birds have long been nature’s masters of flight. Their ability to glide, dive, and twist through the air with ease has fascinated both scientists and engineers. But there's more to bird flight than ...

The sight of birds soaring through the sky has inspired humans for generations before the invention of powered flight in the early 20th century. Still looking to learn from winged animals, a team of ...

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 ...
