An experimental Airbus concept shows airplanes flying in formation to save fuel. This concept carefully capitalizes on wake turbulence, which engineers have fought against for more than a century.
aircraft, part of the Autonomous Formation Flight (AFF) project based at NASA’s Dryden Flight Research Center, Edwards, Calif., flew the mission in early December. During the 96-minute flight, the ...

Wingtip Vortices: They're One of the Costs of Lift
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, ...
When Airbus in November announced it would demonstrate energy-saving automated formation flight in 2020 using two A350s, and Boeing subsequently revealed it had flight-tested the concept in 2018 with ...
The Antonov An-225 Mriya is a giant flying machine. The only built Antonov An-225 Mriya (NATO reporting name: Cossack) strategic airlift cargo aircraft is continuing to fly COVID-19 missions across ...
This video shows how NASA studied wingtip vortices using a C-5A Galaxy about 50 years ago. Although they dissipate at a certain distance from the wing, wingtip vortices, that form because of the ...
The study of vortex dynamics in fluid mechanics is critical for both advancing aeronautical design and minimising flow-induced hazards. At its core, vortex dynamics examines the formation, evolution, ...
