This paper addresses the unsteady aerodynamic mechanisms in the hovering flight of the DelFly II flapping-wing Micro Aerial Vehicle (MAV). Stereoscopic Particle Image Velocimetry (Stereo-PIV) were carried out around the wings at a high framing rate. Thrust-force was measured to investigate the relation between the vortex dynamics and the aerodynamic force generation. The results reveal that the Leading-Edge-Vortex (LEV), as well as the high flexibility of the wings, have a major effect on thrust generation. Comparison of three wing pairs with different aspect ratio (AR) is also reported, yielding significant differences in both vortical structures and thrust generation.

Flow Visualization around a Flapping-Wing Micro Air Vehicle in Free Flight Using Large-Scale PIV Herrero, Alejandro del Estal; Perçin, Mustafa; Karasek, Matej; van Oudheusden, Bas (2018-12-01) Flow visualizations have been performed on a free flying, flapping-wing micro air vehicle (MAV), using a large-scale particle image velocimetry (PIV) approach. The PIV method involves the use of helium-filled soap bubbles (HFSB) as tracer particles. HFSB scatter light with much higher intensity than regular seeding particles, comparable to that reflected off the flexible flapping wings. This enables flow field visualization to be achieved close to the flapping wings, in contrast to previous PIV experiments ...
Flow visualization around a flapping-wing micro air vehicle in free flight Del Estal Herrero, Alejandro; Perçin, Mustafa; Karasek, Matej; Van Oudheusden, Bas W.

The PIV method involves the use of helium filled soap bubbles (HFSB) as tracer particles.

Aerodynamic characterization of 'DelFly Micro' in forward flight configuration by force measurements and flow field visualization Deng, Shuanghou; Perçin, Mustafa; van Oudheusden, Bas (2015-01-01) This study explores the flow structures and unsteady force generation mechanisms of a flapping-wing micro air vehicle 'DelFly Micro' in forward flight configuration. Stereoscopic Particle Image Velocimetry (Stereo-PIV) measurements were performed to acquire three dimensional flow fields in the wake. Six components of forces and moments were captured simultaneously by use of a miniature force sensor.
Experimental Investigation of Aerodynamics of Flapping-Wing Micro-Air-Vehicle by Force and Flow-Field Measurements Deng, Shuanghou; Perçin, Mustafa; van Oudheusden, Bas (2016-02-01) This study explores the aerodynamic characteristics of a flapping-wing micro aerial vehicle (MAV) in hovering configuration by means of force and flowfield measurements. The effects of flapping frequency and wing geometry on force generation were examined using a miniature six-component force sensor. Additional high-speed imaging allowed identification of the notable different deformation characteristics of the flexible wings under vacuum condition in comparison to their behavior in air, illustrating the re...
FLUID-STRUCTURE INTERACTION ANALYSIS OF A FOUR-BAR FLAPPING WING MECHANISM Beker, Can; Turgut, Ali Emre; Arıkan, Kutluk Bilge; Kurtuluş, Dilek Funda (2019-07-11) In this paper, it is introduced to find net aerodynamic lift capacity of proposed flapping-wing micro air vehicle (FWMAV) by performing dynamical calculation and FSI (Fluid Structure Interaction) analysis of a flapping wing test system. In the flapping system, a single degree of freedom type four-bar mechanism which was used as a piezo-driven flapping wing mechanism in previous literature studies is implemented to create beating motion of the wings. For the wing structure, Calliphora Erythocephala’s wing is...
