A computational study of the aerodynamic performance of a dragonfly wing section in gliding flight.
A comprehensive computational fluid-dynamics-based study of a pleated wing section based on the wing of Aeshna cyanea has been performed at ultra-low Reynolds numbers corresponding to the gliding flight of these dragonflies. In addition to the pleated wing, simulations have also been carried out for its smoothed counterpart (called the 'profiled' airfoil) and a flat plate in order to better und...
متن کاملStructural Analysis of a Dragonfly Wing
Dragonfly wings are highly corrugated, which increases the stiffness and strength of the wing significantly, and results in a lightweight structure with good aerodynamic performance. How insect wings carry aerodynamic and inertial loads, and how the resonant frequency of the flapping wings is tuned for carrying these loads, is however not fully understood. To study this we made a three-dimensio...
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...

Recently, there has been a great deal of interest in the application of formal methods, in particular precise formal notations and automatic analysis tools, for the creation and analysis of artifacts of requirements engineering. In this paper we discuss the role of formal methods in requirements engineering (RE), emphasizing that in contrast to their more conventional application in RE for the ...
