Who is the beetle that can fold its delicate wings into an origami shape, keeping them safely tucked away as it scampers ...

Robotic bat wings could aid in the design of novel flapping aircraft, ... Trials with and without wing folding revealed folding the wing on the upstroke increased net lift by 50 percent.

Bat wings are like hands: meaty, bony and full of joints. A new study finds that bats take advantage of their flexibility by folding in their wings on the upstroke to save inertial energy. The ...

Some birds fold their wings in a superficially similar way, but bat wings retract and fold with particular efficiency, almost like closing hands -- which, after all, is what they are, as bat wings ...

It’s based on the wing of a lesser dog-faced fruit bat. Flapping wing aircraft (and animals) generate lift by flapping down and by folding their wings back a bit; think of hunching your ...

An upward moving wing should force the bat down, but the nature of the folding decreases this force by 50 percent. It isn’t just wind tunnel tests that yield knowledge. Building the simplified ...

They created a wing that could actively fold and expand just like a real bat wing, but which was built to focus on the effects of flapping wings on aerodynamic force. The Importance of Making Mistakes ...

Researchers have developed a robotic bat wing that is providing valuable new information about dynamics of flapping flight in real bats. From an engineering perspective, the researchers hope the ...

The dream of flying has always fascinated humanity. In evolutionary history, the ability to fly has emerged independently ...

STUNT FLIER Bat Bot, a batlike robot with flexible wings, can fly straight, bank turn and do sharp dives. The robot still needs a net to land, though, to protect the delicate onboard electronics. A.
