Effects of Flexibility on the Aerodynamic Performance of Flapping Wings
Effects of chordwise, spanwise, and isotropic flexibility on the force generation and propulsive efficiency of flapping wings are elucidated. For a moving body immersed in viscous fluid, different types of forces, as a function of the Reynolds number, reduced frequency (k), and Strouhal number (St), acting on the moving body are identified based on a scaling argument. In particular, at the Reyn...
متن کاملAerodynamic effects of flexibility in flapping wings.
Recent work on the aerodynamics of flapping flight reveals fundamental differences in the mechanisms of aerodynamic force generation between fixed and flapping wings. When fixed wings translate at high angles of attack, they periodically generate and shed leading and trailing edge vortices as reflected in their fluctuating aerodynamic force traces and associated flow visualization. In contrast,...
متن کاملThe Effects of Wing Planforms on the Aerodynamic Performance of Thin Finite-Span Flapping Wings
A three-dimensional high-order unstructured dynamic grid based spectral difference (SD) Navier-Stokes (N-S) compressible flow solver with low Mach number preconditioning is used to investigate the effects of wing planforms on the aerodynamics performance of the thin finite-span flapping wings in this paper. Two types of wings, namely the rectangular and bio-inspired wings, are simulated and com...
متن کاملEffects of Ipsilateral Wing-Wing Interactions on Aerodynamic Performance of Flapping Wings
Dragonflies are masters of using the ipsilateral wing-wing interaction for different kinds of flying modes. It has been discovered that the phase difference between ipsilateral forewings and hindwings plays important role on wing aerodynamic performance. In the current study, we continue our research of a modeled dragonfly in slow flight (Liang and Dong (2009)) by varying the phase difference b...
متن کاملthe effects of planning on accuracy and complexity of iranian efl students’ written narrative task performance
this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
