Flapping wing aerodynamics: from insects to vertebrates

DD Chin, D Lentink - Journal of Experimental Biology, 2016 - journals.biologists.com
More than a million insects and approximately 11,000 vertebrates utilize flapping wings to
fly. However, flapping flight has only been studied in a few of these species, so many …

High aerodynamic lift from the tail reduces drag in gliding raptors

JR Usherwood, JA Cheney, J Song… - Journal of …, 2020 - journals.biologists.com
Many functions have been postulated for the aerodynamic role of the avian tail during steady-

Using high-resolution videogrammetry, we reconstructed accurate and detailed three …

Kinematics and aerodynamics of avian upstrokes during slow flight

KE Crandell, BW Tobalske - The Journal of experimental …, 2015 - journals.biologists.com
Slow flight is extremely energetically costly per unit time, yet highly important for takeoff and
survival. However, at slow speeds it is presently thought that most birds do not produce …

Aerodynamic efficiency of gliding birds vs comparable UAVs: a review

Aerodynamic consequences of wing morphing during emulated take-off and gliding in birds

B Klaassen van Oorschot, EA Mistick… - Journal of …, 2016 - journals.biologists.com
Birds morph their wings during a single wingbeat, across flight speeds and among flight
modes. Such morphing may allow them to maximize aerodynamic performance, but this …

Aerodynamic performance of the locust wing in gliding mode at low Reynolds number

J Xiang, J Du, D Li, K Liu - Journal of Bionic Engineering, 2016 - Elsevier
Gliding is an important flight mode for insects because it saves energy during long distance
flight without wing flapping. In this study, we investigated the influence of locust wing …
