100 years ago: Mechanism of the flight of birdsNo Abstract available for this article.doi:10.1038/331562b0NoneNature Publishing Group UKNature
The flight of a bird is referred to as the state of movement that birds use while taking off and flying. Amongst all of the most complex forms of locomotion, the flight of a bird is one. To feed, breed, avoid predators and during migration, flight assists the birds.there had been. V...

This paper focuses on the control optimization problem of the unmanned aerial vehicle (UAV) biomimetic formation. Since the up wash airflow produced by leading wild geese can save the energy consumption of wild geese in the flight, the proportion-integral-derivative (PID) controller based on the...
Further trials with 3-O-methyl-D-glucose revealed high bioavailability in wattlebirds (90+/-5%). This non-metabolisable glucose analogue remains the probe of choice for measuring uptake rates in vivo, especially in birds in which absorption and metabolism occur extremely rapidly. 展开 ...

The mechanics of avian take-off are central to hypotheses about flight evolution, but have not been quantified in terms of whole-body movements for any spe... KD Earls - 《Journal of Experimental Biology》 被引量: 410发表: 2000年 Power requirements for horizontal flight in the pigeon Columba...
The reflectance of both yellow-green and deep-brown elytra increases as the incidence angle increases from 0° to 60°. The microstructure and changes in the refractive index are the main factors that influence the process of reversible color change. According to the simulation, the lower ...
In this chapter, we consider wing morphing in its broadest sense as any functional change in wing shape occurring during the course of flight. In flying animals, this encompasses those changes in wing shape that are associated with maneuver control, and those that are associated with ...
