Wing flexibility governs the flying performance of flapping-wing flyers. Here, we use a self-propelled flapping-wing model mounted on a "merry go round" to investigate the effect of wing compliance on the propulsive efficiency of the system. Our measurements show that the elastic nature of the wings can lead not only to a substantial reduction in the consumed power, but also to an increment of the propulsive force. A scaling analysis using a flexible plate model for the wings points out that…

Effects of mass and chordwise flexibility on 2D self-propelled flapping wings
Rather than resonance, flapping wing flyers may play on aerodynamics to improve performance
It is shown that flapping flyers optimize their performance not by especially looking for resonance to achieve larger flapping amplitudes with less effort, but by tuning the temporal evolution of the wing shape to optimize the aerodynamics.
Four-Winged Flapping Flyer in Forward Flight
We study experimentally a four-winged flapping flyer with chord-wise flexible wings in a self-propelled setup. For a given physical configuration of the flyer (i.e. fixed distance between the
Experimental and computational studies of the aerodynamic performance of a flapping and passively rotating insect wing
Flapping wings are important in many biological and bioinspired systems. Here, we investigate the fluid mechanics of flapping wings that possess a single flexible hinge allowing passive wing pitch
Effects of Flexibility on the Aerodynamics of a Hovering Flexible Airfoil at Reynolds Number of 100 to 1000
It is shown that the phase lag between the prescribed plunging motion and the passive pitch can be varied by adjusting the frequency ratios, capable of producing advanced, synchronized, or delayed rotation modes.
Modeling and parametric study of a flexible flapping-wing MAV using the bond graph approach
It is shown that the proposed bond graph model not only provides an efficient virtual dynamic framework to resolve the complexity of modeling the flexible flapping-wing MAVs but also can simplify and accelerate the process of sensitivity analysis of such complex systems.

A coupled aerodynamics/structural dynamics model can be established for hovering, based on a linear beam equation with the Morison equation to account for both added mass and aerodynamic damping effects, and it is shown that both instantaneous wing deformation and lift can be predicted in a much simplified framework.

An analytical model and scaling of chordwise flexible flapping wings in forward flight
This study derives an analytical fluid-structure interaction model for a chordwise flexible flapping two-dimensional airfoil in forward flight and derives a novel aeroelastic frequency ratio, which scales with the wing deformation, lift, and thrust.


Flexible Wings and Fins: Bending by Inertial or Fluid-Dynamic Forces?1
A combination of computational and analytic methods are used to explore how bending stresses arising from inertial-elastic mechanisms compare to those stresses that arise from fluid pressure forces, and suggest that for certain combinations of wing stiffness, wing motions, and fluid density, fluid pressure stresses play a relatively minor role in determining wing shape.

The full-fidelity model achieved greater power economy than the uncambered model, which performed better than the untwisted model, showing that the details of insect wing topography and deformation are important aerodynamically.

To better understand the role of wing and fin flexibility in flapping locomotion, we study through experiment and numerical simulation a freely moving wing that can “pitch” passively as it is
Influence of flexibility on the aerodynamic performance of a hovering wing
It was found that flexibility can enhance aerodynamic performance and that the best performance is realized when the wing is excited by a non-linear resonance at 1/3 of the natural frequency, which points to the importance of considering non- linear resonances for enhancing aerodynamics performance.
Symmetry breaking leads to forward flapping flight
Flapping flight is ubiquitous in Nature, yet cilia and flagella, not wings, prevail in the world of micro-organisms. This paper addresses this dichotomy. We investigate experimentally the dynamics of
Drag reduction through self-similar bending of a flexible body
This work uses a flexible fibre immersed in a flowing soap film to measure the drag reduction that arises from bending of the fibre by the flow, and uses a model that couples hydrodynamics to bending to predict a reduced drag growth compared to the classical theory.
Flexural stiffness in insect wings I. Scaling and the influence of wing venation
This study addresses the relationship between venation pattern and wing flexibility by measuring the flexural stiffness of wings (in both the spanwise and chordwise directions) and quantifying wing venation in 16 insect species from six orders and demonstrates that leading edge veins are crucial in generating this spanwise-chordwise anisotropy.
