Crow instability (original) (raw)
In aerodynamics, the Crow instability, or V.C.I. vortex crow instability, is an inviscid line-vortex instability, named after its discoverer S. C. Crow.The Crow instability is most commonly observed in the skies behind large aircraft such as the Boeing 747. It occurs when the wingtip vortices interact with contrails from the engines, producing visible distortions in the shape of the contrail.

Crow. Elle est le plus souvent observée dans les cieux derrière de gros avions, tels que le Boeing 747, lorsque le tourbillon marginal produit au bout des ailes interagit avec la traînée de condensation produite par les moteurs. Le résultat est une distorsion dans la forme de la traînée. (fr) |
