Riassunto
The current research considers the generation and behaviour of the vortices involved in
the motion of the MAV DelFly II. The goal of this thesis is to:
Perform force measurements and flow visualizations around the wing and in the wake of the flapping wing MAV 'DelFly II' in hovering flight regime.
Using time-resolved Stereo-PIV and simultaneous force measurements, it will be investigated how the vortical structures evolve and relate this to the force generation experienced by the wings. The Stereo-PIV results are used to reconstruct the three-dimensional wake of the DelFly.
Three wing pairs with di erent span will be also tested to examine the influence of the Aspect Ratio (AR).
