2. 1. In the wake of a bird - Quantifying aerodynamic performance of avian flight

   Author : Marco Klein Heerenbrink; Evolutionär ekologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; animal flight; flight performance; gliding; powered flight; wing morphology; aerodynamics; biomechanics; birds; jackdaw; Corvus monedula; wind tunnel; PIV;

   Abstract : Flight is an expensive form of locomotion, but also offers the ability to travel great distances at relatively low cost. Birds have developed various adaptations for optimizing flight performance. The main aim of this thesis is to identify how morphological variables in birds affect aerodynamic drag and flight performance. READ MORE

4. 2. Always on the wing - Fluid dynamics, flight performance and flight behavior of common swifts

   Author : Per Henningsson; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Apus apus; aerodynamics; animal flight; kinematics; vortex wake; digital particle image velocimetry; DPIV; common swift; tracking radar; wind tunnel; migration; roosting flight;

   Abstract : The aerodynamics and kinematics behind the flight of animals are relatively unknown. Although animal flight has been studied for several hundreds of years, it is only in recent time that we have the technical abilities to study the mechanistic basis of animal flight. READ MORE

5. 3. Feathers by day, membranes by night - Aerodynamic performance in bird and bat flight

   Author : Florian Muijres; Evolutionär ekologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; animal flight; aerodynamics; vortex wake; actuator disk; flight performance; span efficiency; bird; bat; wind tunnel; PIV; Pied Flycatcher; Glossophaga soricina; Leptonycteris yerbabuenae;

   Abstract : The efficiency and performance of a flying animal is directly related to the aerodynamics around its body and flapping wings. Here, I have developed methods for quantifying the wake dynamics around a flying animal. The results are used to estimate the aerodynamic performance of flapping flight. READ MORE

6. 4. Catching the invisible - aerodynamic tracks and kinematics of bat and bird flight

   Author : Marta Wolf; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; flight; bats; birds; kinematics; vertebrates; aerodynamics;

   Abstract : This thesis is about the flight of vertebrates and the studies of different modes of flight. Flight has always fascinated mankind and this fascination gave inspiration for our attempts at flying. READ MORE
