The spectrum of animal flight: insects to pterosaurs
Progress in Aerospace Sciences, 2000Abstract This paper summarises available data on the geometry and flight characteristics of all types of winged animals, including insects, gliders, birds, bats and pterosaurs. Helicopter momentum stream tube theory has been adapted for the estimation of the upper size limits for flying animals in gliding, hovering, solitary and formation flight, and

On the aerodynamics of animal flight in ground effect
Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1991Abstract Flight in ground effect above a flat, smooth surface may give an animal considerable performance advantages, including a reduction in cost of transport of up to 15%, and a reduction in mechanical flight power of as much as 35%, compared with values for flight out of ground effect.

A New Approach to Animal Flight Mechanics
Journal of Experimental Biology, 1979ABSTRACT The mechanics of lift and thrust generation by flying animals are studied by considering the distribution of vorticity in the wake. As wake generation is not continuous, the momentum jet theory, which has previously been used, is not satisfactory, and the vortex theory is a more realistic model. The vorticity shed

A vortex theory of animal flight. Part 2. The forward flight of birds
Journal of Fluid Mechanics, 1979The vortex wake of a bird in steady forward flight is modelled by a chain of elliptical vortex rings, each generated by a single downstroke. The shape and inclination of each ring are determined by the downstroke geometry, and the size of each ring by the wing circulation; the momentum of the ring must overcome parasitic and profile drags and the bird ...
