Pitch and roll control mechanism for a hovering flapping wing MAV

Hovering flapping flight is inherently unstable and needs to be stabilized actively. We present a control mechanism that modulates independently the wing flapping amplitude and offset by displacing joints of a flapping linkage mechanism. We demonstrate its performance by high speed camera recordings of the wing motion as well as by direct...

Effect of chordwise deformation on unsteady aerodynamic mechanisms in hovering flapping flight

A three-dimensional simulation of hovering flapping wings was performed using an immersed noundary method. This was done to investigate the effects of chordwise wing deformation on three important unsteady aerodynamic mechanisms found in flapping flight, namely Leading Edge Vortex (LEV) shedding, wake capture and clap and fling. A wing was...
