SUMMARY:Henja-Niniane Wehmann (Rostock University): Insect wing flexibility
  with an emphasis on flies
DESCRIPTION:Henja-Niniane Wehmann: \nWhen flying\, many insects perform com
 plex flight behaviours using their wings. Insect wings are flexible body a
 ppendages and can bend and twist in flight. Their properties vary across d
 ifferent species\, but overall there seem to be possible benefits of defor
 mable over rigid wings. For certain configurations\, flexible wings have b
 een shown to be aerodynamically favourable\, although in other experiments
  the opposite was found to be true.\nIn order to further investigate the a
 reodynamic effects of flexibility\, we plan to create a flexible fly wing 
 model to be used in computational fluid dynamics simulations. As a biologi
 cal basis for this model\, we have conducted static stiffness measurements
  of fly wings by locally applying small point forces on wings fixed at the
  wing base. In this talk\, I will present these experiments and their resu
 lts. We found spring stiffnesses between ca. 0.02 to 1.0 N/m in fruit flie
 s and  ca. 0.2 and 2.8 N/m in blowflies. While the line between point of 
 force application and wing base can be approximated as a cantilever beam f
 or the small deformations induced in these experiments\, the wing also sho
 ws deformation along other directions.\n\n\n\n\nM. Sc. Henja-Niniane Wehma
