Bats are flying mammals. Think about that. Many millions of years after birds hollowed out their very bones in pursuit of flight, some gliding, insectivorous squirrel-thing was born with a slight ...

A simplified representation of the strong vortices associated with the unsteady aerodynamics of bat flight at slow speeds. The vortices can be thought of as causing the surrounding air to rotate ...

Staying aloft when hovering and flying slowly is demanding. According to quasi--steady-state aerodynamic theory, slow-flying vertebrates should not be able to generate enough lift to remain aloft.

A robotic bat wing flapping in a university lab is providing researchers with a new appreciation for the wonders of nature and hints at a new generation of mini flapping planes to be deployed on ...
