Birds use a thumb-like structure on the wing to create a small vortex which makes their turns and landings smooth, new research shows. This is the first time that researchers have found evidence that ...

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 ...

For the first time, researchers have observed that birds that fly actively and flap their wings save energy. Biologists at Lund University in Sweden have now shown that jackdaws minimise their energy ...

A wing-tip vortex from a Boeing 747 may have hit wind shear and intensified enough to contribute to the upset that doomed American Airlines Flight 587, a scientist from Canada's National Research ...

Portuguese wet-lease operator Hi Fly is to use an Airbus A330 as a testbed for a wing-tip modification which is intended to reduce fuel burn on the type. The radical wing-tip design – branded ...
