Aerodynamic 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 کاملEffects 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 کاملAutomated aerodynamic performance estimates for flapping flight
The aerodynamic performance of freely flying birds is inherently difficult to measure directly without interfering with their natural flight. Many current methods thus combine kinematic parameters derived from high-speed video with theoretical force and power models. However, these methods often require manual tracking of points in each frame of a video to obtain kinematic data. This project ut...
متن کاملLoading Estimation of Flapping Wings under Aeroelastic Effect Using Finite Element Method
The aim of this paper is to provide an aeroelastic computational tool which determines the induced wing loads during flapping flight. For this purpose, a Finite Element (FE) code based on a four-node plate bending element formulation is developed to simulate the aeroelastic behavior of flapping wings in low incompressible flow. A quasi-steady aerodynamic model is incorporated into the aeroelast...
متن کاملFlow interactions lead to orderly formations of flapping wings in forward flight
Classic models of fish schools and flying formations of birds are built on the hypothesis that the preferred locations of an individual are determined by the flow left by its upstream neighbor. Lighthill posited that arrangements may in fact emerge passively from hydroor aerodynamic interactions, drawing an analogy to the formation of crystals by intermolecular forces. Here, we carry out physic...
