Rows of flaps inspired by bird wing feathers improve airfoil performance by boosting lift, reducing drag and mitigating stall.

Modern airplanes are inspired by birds but Princeton researchers find one aspect, we have not used so far and it could help ...

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 ...
