Animal flight performance has been studied using models developed for man-made aircraft. For an aeroplane with fixed wings, the energetic cost as a function of flight speed can be expressed in terms ...
Mosquitoes flap their wings not just to stay aloft but for two other critical purposes: to generate sound and to point that buzz in the direction of a potential mate, researchers at Johns Hopkins ...
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 ...
