Direct aerodynamic force measurements in avian flight support active upstroke hypothesis
Meeting Abstract 20.5 Friday, Jan. 4 Direct aerodynamic force measurements in avian flight support active upstroke hypothesis LENTINK, D; Stanford University; Wageningen University; Harvard University dlentink@stanford.edu Birds dynamically change the shape of their wing during the stroke, resulting in dramatic differences in wing shape between the up- and down-stroke. The wing is partially folded during the upstroke, […]
