An improved aerodynamic model for quasi-steady simulations of animal flight at moderate Reynolds numbers
Yunxing Su, Xiaozhou Fan, Kyohei Onoue +2
We report on experimental and numerical studies aimed at developing an improved paradigm to model animal flight at moderate Reynolds numbers (). A series of experimen…

Upstroke wing clapping in bats and bat-inspired robots improves both lift generation and power economy
Xiaozhou Fan, Alberto Bortoni, Siyang Hao +2
Wing articulation is critical for efficient flight of bird- and bat-sized animals. Inspired by the flight of , the lesser short-nosed fruit bat, we…

Wing twist and folding work in synergy to propel flapping wing animals and robots
Xiaozhou Fan, Alexander Gehrke, Kenneth Breuer
We designed and built a three degrees-of-freedom (DOF) flapping wing robot, Flapperoo, to study the aerodynamic benefits of wing folding and twisting. Forces and moments of this ph…
