Lockheed Martin Aeronautics Company’s Advanced Development Programs sector is proposing a morphing wing design that can be locked into either an expanded or contracted position. Key to enabling this ...

The Ikhana unmanned aircraft system has been used by NASA last year to fight wildfires from the sky and this month to provide images of current Californian wildfires to authorities (link to NASA ...

An analysis of hoverfly flight shows that wing design, not faster flapping, enables the smallest species to generate enough lift to fly. The study, published today in eLife as the final Version of ...

American space agency NASA and aerospace giant Boeing still haven't given up on the truss-braced wing configuration (TBW) ...

In 2014 and 2015, at NASA’s Armstrong Flight Research Center in Edwards, California, a strange-looking twin-boom aircraft called Proteus spent six months flying with wings that bent instead of ...

To maximize a plane's efficiency over a broader range of flight speeds, Penn State engineers have developed a concept for morphing airplane wings that change shape like a bird's and are covered with a ...

Even the giant wings of the albatross are not ‘optimally’ shaped for their extraordinary long-distance migrations, according ...

Most bird wings are far from aerodynamically optimal, suggesting evolution often settles for “good enough” instead of perfect ...

Scientists have long wondered how butterflies fly – compared with other flying animals, the creatures have unusually short, broad and large wings relative to their body size. Now, experts have found ...

Bird dispersal movements are thought to depend on complex demographic and genetic factors. Researchers show that there may be a simpler explanation: bird dispersal distances depend on the morphology ...
