Firstly, the deformation of a single hindwing has been studied. Secondly, the dragonfly model is enriched by incorporating the forewing and a simplified thorax geometry. Preliminary results highlight the complex dynamic of the fluid around the body as well as the efficiency of the proposed mesh...
DragonflyThis paper is concerned with the wing structure and the aerodynamic characteristics of a flyingdragonfly. The structural properties of dragonfly wings were studied through the measurements ofsome morphological parameters. The scanning electron microscopic observation showed themorphological ...
We implement the interaction between a body and wing in the fluidstructure interaction analysis, and solve the free-flight situation, where the wing lifts the body and the body actuates the wing. Although the modeled dragonfly is artificially designed to have only two wings to avoid needing to...
Application of fluid–structure interaction analysis to flapping flight of insects with deformable wings The aerodynamic advantage of the dragonfly''s flexible wing during hovering is quantitatively investigated. The flapping flight of insects, which have simp... M Hamamoto,Y Ohta,K Hara,... - 《...
We found that finite element analysis based on the arbitrary LagrangianEulerian method can handle the problem accurately. We established customized modeling methods for such a deformable wing and its actuation, and tested its adequacy on actual dragonfly hovering. Then, we compared the aerodynamic ...
However, the wing bases of fossil Odonata have never been described hitherto. Herein, we describe the fourth burmaeshnid dragonfly, Proaeschna zhangi gen. et sp. nov., from the Burmese amber with well-preserved wing base structure. Detailed examination and illustrations are carried out to ...

A Permutational Analysis of Variance - PERMANOVA (Anderson and Walsh, 2013) was used to test the hypothesis that the latent classes are structured phylogenetically and by species with a similar size body. The significance of the PERMANOVA was calculated using a Monte Carlo test with 999 permutation...
