The aerodynamic benefit of wing-wing interaction depends on stroke trajectory in flapping insect wings.
Flying insects may enhance their flight force production by contralateral wing interaction during dorsal stroke reversal ('clap-and-fling'). In this study, we explored the forces and moments due to clap-and-fling at various wing tip trajectories, employing a dynamically scaled electromechanical flapping device. The 17 tested bio-inspired kinematic patterns were identical in stroke amplitude, st...
متن کاملThe aerodynamic effects of wing-wing interaction in flapping insect wings.
We employed a dynamically scaled mechanical model of the small fruit fly Drosophila melanogaster (Reynolds number 100-200) to investigate force enhancement due to contralateral wing interactions during stroke reversal (the ;clap-and-fling'). The results suggest that lift enhancement during clap-and-fling requires an angular separation between the two wings of no more than 10-12 degrees . Within...
متن کاملComputational Fluid-Structure Interaction of a Deformable Flapping Wing for Micro Air Vehicle Applications
Motivated by micro air vehicle applications, a fluid-structure coupling procedure between a NavierStokes solver and a three-dimensional FEM beam solver is presented along with selected results highlighting some of the aerodynamics implications. The fluid model includes laminar, the k ε − turbulence closure, and a filter-based k ε − closure. The structural model is based on an asymptotic approxi...
متن کاملArtificial insect wings of diverse morphology for flapping-wing MAVs
The development of flapping-wing micro air vehicles (MAVs) demands a systematic exploration of the available design space to identify ways in which the unsteady mechanisms governing flapping-wing flight can best be utilized for producing optimal thrust or maneuverability. Mimicking the wing kinematics of biological flight requires examining the potential effects of wing morphology on flight per...
متن کاملModeling and Simulation of the Fluid-Structure Interactions in Passively-Pitching Flapping Wings of Flying Microrobots
We present a study of the dynamics of passive wing-pitching in flapping-wing hovering flight, employing an integrated simulation approach. Here, the motion of a perfectly rigid wing is described using the Euler-Lagrange equation in Kane’s formulation, in which the passive rotating mechanism (flexure hinge) is modeled as a single-axis elastic beam and the total aerodynamic moment is computed by ...
