A bird banking in a crosswind doesn't rely on spinning blades. Its wings flex, twist and respond instantly to its environment ...

The strong, flapping flight of bats offers great possibilities for the design of small aircraft, among other applications. By building a robotic bat wing, Brown researchers have uncovered flight ...

A simulation study was initiated to investigate alternative wing and flap controls for tilt-wing aircraft. The initial phase of the study compared the flying qualities of both a conventional ...

Insects are thought to use specific chest muscles to actively open and close their wings. However, high-speed imaging reveals that rhinoceros beetles flap their hindwings to deploy them for flight, ...

The role of unmanned aerial vehicles (UAVs) has expanded rapidly in both military and civilian circles over the past decade and although most designs to date are miniature versions of conventional ...

The world's first successful flight of a self-powered, rudderless, flapping aircraft has been achieved by engineers from AeroVironment. The NAV, or nano air vehicle, operates by using two flapping ...

Zabdiel Avives flew across New York, gliding over and around buildings on the landscape — but the 12-year-old boy only had to travel about a dozen miles from his Maywood home for the experience. He ...

Flap your arms for a while and you’ll soon notice that the constant cycle of acceleration and deceleration requires and even wastes huge amounts of energy. And yet for birds, wing flapping is a highly ...

A new study into the flight characteristics of condors — the largest soaring birds on Earth — finds that they rarely flap their wings once airborne. Condors are capable of flying for over a hundred ...
