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 ...

Icing poses a severe and insidious threat to aircraft, significantly degrading aerodynamic performance (reducing lift, increasing drag) even with minimal accumulation, and can quickly lead to critical ...

Even the giant wings of the albatross are not "optimally" shaped for their extraordinary long-distance migrations, according to new University of Bristol research. The study, published in Nature ...

Foldable wings have played an obscure part in aviation since its earliest days when the Wright brothers used pulleys and levers to twist the trailing edges of wings. However, as planes got more ...

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 ...

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 ...
