(PhysOrg.com) -- Since the days of Leonardo da Vinci people have tried to build machines that fly with flapping wings like a bird or an insect. Even in the jet age the idea remains attractive because ...

(PhysOrg.com) -- According to a new Cornell study, an optimized flapping wing could actually require 27 percent less power than its optimal steady-flight counterpart at small scales. In the search for ...

Discover how the European nightjar's wings are a unique evolution, balancing long-distance travel and agile hunting, ...

Jerry Seinfeld launched his career with Bee Movie, an insect-themed animated feature that took the world by storm in 2007. It posed the quandary – that supposedly, according to all known laws of ...

Professor Hiroshi Liu has developed a 2.6-gram, 4-inch flapping-wing micro air vehicle (MAV) capable of six minutes of flight, which has successfully demonstrated stable figure-eight flight. This MAV ...

Over half a millennium ago, Leonardo da Vinci sketched the first human-powered ornithopter. For centuries since, engineers have attempted to build a human-powered aircraft with flapping wings. Now, a ...

Birds fly more efficiently by folding their wings during the upstroke, according to a recent study. The results could mean that wing-folding is the next step in increasing the propulsive and ...

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 ...

Drones of the future won't just fly alongside birds. They'll actually fly a lot like them, thanks to a new Army program that's looking to mimic avian flight in the development of new unmanned vehicles ...

Although wing-flapping micro-drones do already exist, the things tend to be quite fragile – and thus not ideally suited to real-world use. An experimental new one, however, utilizes a softer mechanism ...

Taking their cues from the birds, Airbus engineers have flown a scale-model airplane that incorporates flapping wing-tips. Based on the structure of the albatross wing, the remote-controlled ...
