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

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

   Sammanfattning : 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. LÄS MER
