Dynamics of the Trailing Vortices Near the Ground

Abstract

The vortex behavior near the ground is very important scientific problem for many reasons. At present time, many efforts are being devoted to enable safe improvements in the capacity of the air transportation system by bringing about a reduction in the in-trailspacing of airplanes. The efforts to solve the problem have been directed at investigating of the vortex behavior near the ground and finding ways to reduce the intensity of the vortices. Another important occurrence of vortex-ground interactions is for ekranoplans (wing-in-ground effect crafts). These flying ships move in the operation area of many other marine vehicles and produce the powerful trailing vortices. The study of the vortex behavior near the ground is very important to choose the operating regimes and safe routes of the ekranoplans.
