As I look out of my office window and watch the heart-stopping acrobatics of feeding swifts, it's not difficult to see why so many aircraft designers find inspiration in nature - from birds to bats to ...

A computer model from Cornell University makes it easier to develop stably flying flapping robots.

A new study sheds light on just how efficiently the world’s largest soaring bird rides air currents to stay aloft for hours without flapping its wings. The Andean condor has a wingspan stretching to ...

Flap your arms for a while and you’ll soon notice that the constant cycle of acceleration and deceleration requires and even wastes huge amounts of energy. And yet for birds, wing flapping is a highly ...

The world's first successful flight of a self-powered, rudderless, flapping aircraft has been achieved by engineers from AeroVironment. Subscribe to read this story ad-free Get unlimited access to ...

Using robotic and animal models, researchers have shown that some dinosaurs were already flapping their rudimentary wings as a side effect of running, prior to evolving the ability to fly. The finding ...

Imagine insect-like aircraft capable of military or civilian surveillance missions, impossible for current fixed-wing or rotary-wing vehicles – tiny flying machines able to access buildings reduced to ...

How did the earliest birds take wing? Did they fall from trees and learn to flap their forelimbs to avoid crashing? Or did they run along the ground and pump their "arms" to get aloft? The answer is ...

Engineers at Aeronvironment (AV) of Monrovia, California, have demonstrated the world's first successful flight of the smallest ever self-powered, rudderless, aircraft with flapping wings. The nano ...
