Employing Wing Morphing to Cooperate Aileron Deflection Improves the Rolling Agility of Drones

open access: yesAdvanced Intelligent Systems, 2023
In the wild, gliding birds dodge obstacles or predators by folding and twisting their wings swiftly to perform a rapid roll. Accordingly, the authors strive to explore the feasibility of improving the roll rate of drones through this bird‐inspired ...

Efficiency of Lift Production in Flapping and Gliding Flight of Swifts [PDF]

open access: yes, 2014
Many flying animals use both flapping and gliding flight as part of their routine behaviour. These two kinematic patterns impose conflicting requirements on wing design for aerodynamic efficiency and, in the absence of extreme morphing, wings cannot be ...
