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.

It's common to see line-shaped clouds in the sky, known as contrails, trailing behind the engines of a jet airplane. What's not always visible is a vortex coming off of the tip of each wing--like two ...

For Cinco de Mayo, take a peek south of the border at this beautiful von Karman vortex street trailing behind Guadalupe Islands. The sharply-peaking volcanic island pokes 1.3 kilometers above the ...

Vortex. Vortices. Swirls of air trailing behind wings as they produce lift. You know from the movies what happens to a jet flying through another jet's wake, but what happens to a missile's tail fins ...

A Sept. 17 Facebook post (direct link, archive link) includes multiple images of an airplane leaving several white trails in the sky. “Next time they tell you ‘It's just contrails produced by engine ...

Vortex dynamics and the Navier–Stokes equations constitute a cornerstone of fluid dynamics, offering profound insights into the behaviour of complex flows. Vortices, with their swirling motions and ...

Wakes can be encountered up to 25 nm behind the generating aircraft. The most significant encounters are reported within a distance of 15 nm. Credit: EASA Safety Information Bulletin 2017-10 Fast ...

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 ...
