(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 ...

Insects are thought to use specific chest muscles to actively open and close their wings. However, high-speed imaging reveals that rhinoceros beetles flap their hindwings to deploy them for flight, ...

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 ...

(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 ...

Bio-inspired wind sensing using strain sensors on flexible wings could revolutionize robotic flight control strategy. Researchers have developed a method to detect wind direction with 99% accuracy ...

There are no powered spinning propellers in nature. When evolution has found an advantage to producing thrust in a fluid, it has done it mainly by flapping things back and forth. This new VTOL ...

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 ...
