Aerodynamic characteristics of the wings and body of a dragonfly
TL;DR: The aerodynamic characteristics of the wings and body of a dragonfly and of artificial wing models were studied by conducting two types of wind-tunnel tests and a number of free-flight tests of gliders made using dragonfly wings.
Journal ArticleDOI
Flight Performance of a Dragonfly
Akira Azuma,Tadaaki Watanabe +1 more
TL;DR: The results show that without using any novel unsteady aerodynamic force generated by a separated flow over the wings, the dragonfly can make steady trimmed flight at various flight speeds, from hovering to top speed.
Journal ArticleDOI
Flight Mechanics of a Dragonfly
TL;DR: The results of calculations show that the dragonfly performs low speed flight with ordinary airfoil characteristics, instead of adopting an abnormally large lift coefficient.
Journal ArticleDOI
Performance of a butterfly in take-off flight
TL;DR: The flight of a butterfly was observed in the take-off phase and was analyzed theoretically from aerodynamic and kinetic viewpoints and a vortex method, which was recently developed by the present authors, was used in this analysis.
