A team of researchers from Princeton University is exploring how feather-like flaps on aircraft wings could improve stability ...

Everything about the anatomy of a bird reflects its ability to fly. The wings, for example, are shaped to create lift. The leading edge is thicker than the back edge, and they are covered in ...

To generate lift, a bird has merely to tilt its wings, adjusting the flow of air below and above them. Airplane wings exploit some of the same aerodynamic tricks. But a bird wing is vastly more ...

Three of these control the bird-like wingtips and spreading tail, while the remaining actuators handle more conventional controls: independently twisting wing bases (similar to ailerons ...

These small feathers on top of birds’ wings lay flat during normal flight ... Up to 15% increase in lift and 13% reduction in drag at low speeds. Unfortunately the main body of the paper is ...
