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 ...

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 ...
