B.J. Balakumar's robotic hummingbird wing isn't as pretty as the real thing. It lacks jewel-like colors and the iridescent glint of hummingbird feathers. But what the unadorned metal wing does have is ...

A new mathematical analysis of an aeronautical hazard known as wake turbulence might eventually lead to improved air safety and increase the number of flights at major airports, scientists say.

Scientists from Hiroshima University undertook a study of dragonfly wings in order to better understand the relationship between a corrugated wing structure and vortex motions. They discovered that ...

One mystery of birds' flight is solved! The elegance of birds' flight, their seemingly effortless aerial turns and the softness of their landing, have been envied by many people. From countless ...

Scientists undertook a study of dragonfly wings in order to better understand the relationship between a corrugated wing structure and vortex motions. They discovered that corrugated wings exhibit ...

Recent research demonstrated that, although most wing shapes used today create turbulent wake vortices, wing geometrics can be designed to reduce or eliminate wingtip vortices almost entirely. In the ...

This video shows commercial aircraft taking off and landing at Manchester Airport during heavy rain and poor visibility.

The nonlinear development of stationary crossflow vortices over a 45° swept NLF(2)-0415 airfoil is studied. Previous investigations indicate that the linear stability theories are unable to accurately ...

When people want to talk about something unpleasant, they often invent nicer-sounding phrases to disguise what's really going on. "Wake turbulence" is the kind of term that can bring to mind vague, ...

The swirling wing vortex from an agricultural airplane is highlighed during tests at NASA's Wallops Flight Facility. NASA Langley Research Center Mark Mallari writes from Manila, the Philippines, with ...
