Beyond robins: aerodynamic analyses of animal flight [PDF]
Journal of the Royal Society Interface, 2008 Recent progress in studies of animal flight mechanics is reviewed. A range of birds, and now bats, has been studied in wind tunnel facilities, revealing an array of wake patterns caused by the beating wings and also by the drag on the body. Nevertheless, the quantitative analysis of these complex wake structures shows a degree of similarity among all ...

A new low-turbulence wind tunnel for animal and small vehicle flight experiments [PDF]
Royal Society Open Science, 2017 Our understanding of animal flight benefits greatly from specialized wind tunnels designed for flying animals. Existing facilities can simulate laminar flow during straight, ascending and descending flight, as well as at different altitudes. However, the

A Sensory-Motor Control Model of Animal Flight Explains Why Bats Fly Differently in Light Versus Dark [PDF]
PLoS Biology, 2015 Animal flight requires fine motor control. However, it is unknown how flying animals rapidly transform noisy sensory information into adequate motor commands.

PLoS ONE, 2014 Recent experiments on flapping flight in animals have shown that a variety of unrelated species shed a wake behind left and right wings consisting of both tip and root vortices.

Atmospheric Environment Associated with Animal Flight
, 2017 The atmospheric environment can assist or restrict flight of animals (insects, birds, and bats), influencing their ability to extend their population range and find new habitats for food, mating, and shelter (Pedgley, Windborne pests and diseases: meteorology of airborne organisms.

Animal flight dynamics II. Longitudinal stability in flapping flight.
Journal of Theoretical Biology, 2002 Stability is essential to flying and is usually assumed to be especially problematic in flapping flight. If so, problems of stability may have presented a particular hurdle to the evolution of flapping flight. In spite of this, the stability of flapping flight has never been properly analysed.

Humming hummingbirds, insect flight tones and a model of animal flight sound [PDF]
Journal of Experimental Biology, 2020 Why do hummingbirds hum and insects whine when their wings flap in flight? Gutin proposed that a spinning propeller produces tonal sound because the location of the center of aerodynamic pressure on each blade oscillates relative to an external receiver.

The Aerodynamics of Flapping Animal Flight [PDF]
American Zoologist, 1984 Our understanding of the aerodynamics of flapping animal flight is largely based on the quasi-steady assumption: the instantaneous aerodynamic forces on a flapping wing are assumed to be identical with those which the wing would experience in steady motion at the same instantaneous speed and angle of attack.
