Wake Vortex Evolution during Approach and Landing With and Without Plate Lines

Kurzfassung

Data from numerical simulations and two field measurement campaigns are used to investigate aircraft wake vortex evolution during final approach and landing with an without a plate line. A new hybrid simulation method os employed to capture wake vortex evoltion form early roll-up to final decay in ground proximity. Vortex decay is driven by the turbulence of the aircraft wake itself, the interation of the wake vortices with the ground, the so-called and effects triggered by the sudden loss of lift during toughdorn, and it is artivically augmented by a plate line installed a few hundred meters from the runway theshold.
