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 کاملAerodynamic characteristics of dragonfly wing sections compared with technical aerofoils.
During gliding, dragonfly wings can be interpreted as acting as ultra-light aerofoils which, for static reasons, have a well-defined cross-sectional corrugation. This corrugation forms profile valleys in which rotating vortices develop. The cross-sectional configuration varies greatly along the longitudinal axis of the wing. This produces different local aerodynamic characteristics. Analyses of...
متن کاملEffect of forewing and hindwing interactions on aerodynamic forces and power in hovering dragonfly flight.
Dragonflies are four-winged insects that have the ability to control aerodynamic performance by modulating the phase lag (phi) between forewings and hindwings. We film the wing motion of a tethered dragonfly and compute the aerodynamic force and power as a function of the phase. We find that the out-of-phase motion as seen in steady hovering uses nearly minimal power to generate the required fo...
متن کاملMechanical, Dielectric, and Spectroscopic Characteristics of “Micro/Nanocellulose + Oxide” Composites
The set of composite materials that consist of micro/nanocellulose and complex K2Eu(MoO4)(PO4) luminescent oxide particles was prepared. The composites were studied by means of scanning electron microscopy, XRD analysis, dilatometry, differential scanning calorimetry and thermogravimetric analysis, and dielectric and luminescence spectroscopy.Dependencies of density, crystallinity, relative ext...
