摘要
For reducing a circulation of wake vortexes in a wake turbulence behind an airplane flying over ground at low altitude, at least one ring vortex of airflow is generated at the ground on each side of a vertical middle plane of the airplane. Each ring vortex has a vortex axis and a direction of propagation, wherein the vortex axis is oriented at an angle with regard to the ground, and wherein the propagation direction is oriented upwards from the ground; and each ring vortex disturbs at least one wake vortex to induce its decay.
