Aerodynamic characteristics of the wings and body of a dragonfly
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. The results were consistent between these different tests. The effects of camber, thickness, sharpness of the leading edge and surface roughness on the aerodynamic cha...
متن کاملAntibacterial titanium nano-patterned arrays inspired by dragonfly wings
Titanium and its alloys remain the most popular choice as a medical implant material because of its desirable properties. The successful osseointegration of titanium implants is, however, adversely affected by the presence of bacterial biofilms that can form on the surface, and hence methods for preventing the formation of surface biofilms have been the subject of intensive research over the pa...
متن کاملLong-lasting mobbing of the pied flycatcher increases the risk of nest predation
Mobbing behavior may provide real benefits because mobbing prey individuals often cause a predator to leave the vicinity. However, mobbing calls of prey can attract acoustically oriented predators thus increasing nest predation. Therefore, a real value of mobbing as a type of adaptive behavior may depend on its duration. In this experimental study, we tested whether mobbing duration by the pied...
متن کاملResilin in dragonfly and damselfly wings and its implications for wing flexibility.
Although there is mounting evidence that passive mechanical dynamics of insect wings play an integral role in insect flight, our understanding of the structural details underlying insect wing flexibility remains incomplete. Here, we use comparative morphological and mechanical techniques to illuminate the function and diversity of two mechanisms within Odonata wings presumed to affect dynamic w...
متن کاملEffects of multiple vein microjoints on the mechanical behaviour of dragonfly wings: numerical modelling
Dragonfly wings are known as biological composites with high morphological complexity. They mainly consist of a network of rigid veins and flexible membranes, and enable insects to perform various flight manoeuvres. Although several studies have been done on the aerodynamic performance of Odonata wings and the mechanisms involved in their deformations, little is known about the influence of vei...
