Highly deformable flapping membrane wings suppress the leading edge vortex in hover to perform better
Alexander Gehrke, Karen Mulleners
Airborne insects generate a leading edge vortex when they flap their wings. This coherent vortex is a low pressure region that enhances the lift of flapping wings compared to fixed…

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…

To tread or not to tread: comparison between water treading and conventional flapping wing kinematics
Swathi Krishna, Alexander Gehrke, Karen Mulleners
Hovering insects are limited by their physiology and need to rotate their wings at the end of each back and forth motion to keep the wing's leading edge ahead of its trailing edge.…
