Abstract
The work presented here is aimed at
investigating the effect of the terrain roughness on the
behavior of aircraft wake vortices. The tests are
conducted in the water tunnel with a smooth ground
plane first. Then, streamwise ridges are added to the
ground in order to simulate terrain roughness. In
addition, a case is presented without the ground plane.
This latter data, showing the behavior of the vortices in
the absence of any ground, provides a basis for
comparison as well as allowing calculation of the wake
vortex strengths.
The experimental data shows temporal and spatial
behavior of the vortices. In the cases without a ground
plane and with a smooth ground plane, the water tunnel
measurements are consistent with information in the
literature. With the information garnered from these
tests, the authors are able to quantify the effect of
ground roughness on wake vortex behavior.
