Behind the performance of flapping flyers
A recent field of investigation concerns the efficiency of flapping flyers, the major interrogation being about how natural systems optimize energy saving together with performance enhancement. In particular, the passive role of wing flexibility to increase flight efficiency through the bending of the wings while flapping has attracted a lot of attention. It is commonly agreed that this efficie...
متن کاملFootprints of a flapping wing
Birds have to flap their wings to generate the needed thrust force, which powers them through the air. But how exactly do flapping wings create such force, and at what amplitude and frequency should they operate? These questions have been asked by many researchers. It turns out that much of the secret is hidden in the wake left behind the flapping wing. Exemplified by the study of Andersen et a...
متن کاملGood Vibrations
How and where the brain forms associations between sensation and action are crucial questions in the field of cognitive neuroscience. In this issue of Neuron, add to an already impressive body of work elucidating the neural mechanisms responsible for forming categorical decisions about vibrotactile stimuli that guide behavior. Here they show that single neurons in premotor cortex represent, rem...
متن کاملPassive Wing Rotation in Flexible Flapping Wing Aerodynamics
Insect wings are flexible. For rigid wings lift enhancing unsteady aerodynamics mechanisms, such as delayed stall via leading-edge vortices (LEVs), wake-capture, and rotational forces, characterize the lift generation of a hovering insect. We have uncovered a novel mechanism that fruit fly size insects can utilize to further increase the lift by adjusting its wing shape passively: A pair of a L...
متن کاملDesign and Fabrication of Ultralight High-Voltage Power Circuits for Flapping-Wing Robotic Insects
Flapping-wing robotic insects are small, highly maneuverable flying robots inspired by biologicalinsects and useful for a wide range of tasks, including exploration, environmental monitoring, searchand rescue, and surveillance. Recently, robotic insects driven by piezoelectric actuators have achievedthe important goal of taking off with external power; however, fully autonomous operation requir...
