摘要: This study is concerned with the wing structure and aerodynamic characteristics of a dragonfly in flight. The structural properties wings were studied through measurements certain morphological parameters. scanning electron microscopic observation showed wing. Dragonflies examined small low-turbulence wind tunnel. In experiment on flapping, an optical displacement detector was used to measure velocity fluctuation, hot-wire anemometer field. spectrum flight revealed by fluctuation.
