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 ...

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 ...

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 ...

Researchers attached covert feather-inspired flaps to a 3D-printed model airplane wing and mounted it in a wind tunnel to explore the role of covert feathers in bird flight. By precisely measuring how ...

Birds are pretty amazing creatures, and one of the most amazing things about them and their non-avian predecessors are feathers. Engineers and scientists are finding inspiration from them in ...
