 | In the very early hours of the morning, in a Harvard robotics laboratory last summer, an insect took flight. Half the size of a paperclip, weighing less than a tenth of a gram, it leaped a few inches, hovered for a moment on fragile, flapping wings, and then sped along a preset route through the air. This demonstration of the first controlled flight of an insect-sized robot is the culmination of more than a decade's work, led by researchers at Harvard. ...> Full Article |
 | As of today, the Wikipedia entry for the hummingbird explains that the bird's flight generates in its wake a single trail of vortices that helps the bird hover. But after conducting experiments with hummingbirds in the lab, researchers at the University of California, Riverside propose that the hummingbird produces two trails of vortices -- one under each wing per stroke -- that help generate the aerodynamic forces required for the bird to power and control its flight. ...> Full Article |
While many may have found the movements of whirligig beetles curious, scientists have puzzled over the apparatus behind their energy efficiency -- until now, thanks to a study performed by a team led by Mingjun Zhang, associate professor of mechanical, aerospace and biomedical engineering, at the University of Tennessee, Knoxville.

Owls have the uncanny ability to fly silently, relying on specialized plumage to reduce noise so they can hunt in acoustic stealth. Researchers from the University of Cambridge, England, are studying the owl's wing structure to better understand how it mitigates noise so they can apply that information to the design of conventional aircraft.

 | New research on how birds can fly so quickly and accurately through dense forests may lead to new developments in robotics and auto-pilots. Scientists from Harvard University trained pigeons to fly through an artificial forest with a tiny camera attached to their heads, literally giving a birds-eye view. This research is being presented at the Society for Experimental Biology Annual Main Meeting on July 1. ...> Full Article |
 | A new design of micro air vehicle (MAV) will be able to flap, glide and hover. Researchers have been inspired by birds to design a MAV that combines flapping wings, which will allow it to fly at slow speeds and hover, with the ability to glide, ensuring good quality images from any on-board camera. This work will be presented at the Society for Experimental Biology Annual Conference in Glasgow on July 2, 2011. ...> Full Article |
 | University of Arizona aerospace and mechanical engineers are studying bird and bee flight to develop unmanned vehicles that stay aloft longer and cope with sudden and severe changes in airflow. ...> Full Article |
Working at a crossroad between biology and engineering, scientists have modeled and are now mimicking the ingenious natural design of falling geckos, gliding snakes, cruising seagulls, flapping insects and floating maple seeds to improve the design of air vehicles.

 | Hummingbirds rank among the world's most accomplished hovering animals, but how do they manage it in gusty winds? A team of researchers has built a robotic hummingbird wing to discover the answer, which they describe today at the American Physical Society Division of Fluid Dynamics meeting in Long Beach, Calif. ...> Full Article |
 | To avoid some of the design challenges involved in creating micro-scale air vehicles that mimic the flapping of winged insects or birds, Georgia Tech researchers propose using flexible wings that are driven by a simple sinusoidal flapping motion. ...> Full Article |
 | Airplanes do not look much like birds, but should they? This question is exactly what a pair of engineers in California and South Africa inadvertently answered recently in experiments they describe today at the American Physical Society Division of Fluid Dynamics meeting in Long Beach, Calif. ...> Full Article |
 | The University of Washington is leading a five-year, $7.5 million project to study birds, insects and bats in order to develop autonomous aerial vehicles that can adapt to obstacles and fly in unpredictable conditions. ...> Full Article |
 | How well do flying fish fly? This is the question that puzzled Haecheon Choi from Seoul National University, Korea. Measuring aerodynamic forces on dried darkedged-wing flying fish in a wind tunnel, Choi and Hyungmin Park discovered that flying fish glide better than insects and as well as birds. The fish also derive an aerodynamic advantage from gliding close to the water's surface to cover distances as great as 400 meters. ...> Full Article |
 | To lower the fuel consumption of airplanes and ships, it is necessary to reduce their flow resistance, or drag. An innovative paint system makes this possible. This not only lowers costs, it also reduces CO2 emissions. ...> Full Article |
 | A group of Japanese researchers, who publish their findings today Thursday, May 20, in IOP Publishing's Bioinspiration & Biomimetics, have succeeded in building a fully functional replica model -- an ornithopter -- of a swallowtail butterfly, and they have filmed their model butterfly flying.

 | Researchers are one step closer to creating a micro-aircraft that flies with the maneuverability and energy efficiency of an insect after decoding the aerodynamic secrets of insect flight. ...> Full Article |
 | A six-inch robotic spy plane modeled after a bat would gather data from sights, sounds and smells in urban combat zones and transmit information back to a soldier in real time. ...> Full Article |
 | Natural flyers like birds, bats and insects outperform man-made aircraft in aerobatics and efficiency. University of Michigan engineers are studying these animals as a step toward designing flapping-wing planes with wingspans smaller than a deck of playing cards. ...> Full Article |
