Bird wing aerodynamics
WebAerodynamics, sensing and control of insect-scale flapping-wing flight. There are nearly a million known species of flying insects and 13000 species of flying warm-blooded vertebrates, including mammals, birds and bats. While in flight, their wings not only move forward relative to the air, they also flap up and down, plunge and sweep, so that ... WebThe airplane ranks as one of history's most ingenious and phenomenal inventions--and surely one of the most world-shaking. How ideas about its aerodynamics first came together and how the science and technology evolved to forge the airplane into the revolutionary machine it became is the epic story James R. Hansen tells in The Bird Is …

WebAspect ratio (aeronautics) An ASH 31 glider with very high aspect ratio (AR=33.5) and lift-to-drag ratio (L/D=56) In aeronautics, the aspect ratio of a wing is the ratio of its span to its mean chord. It is equal to the square of the wingspan divided by the wing area.
