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 ...

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 ...

Researchers at Stanford University have used a high-speed laser imaging technique to directly view the wake turbulence generated by a bird in flight for the first time - and discovered that the models ...
