Abstract:

The motion of the pair of trailing vortices generated by an aircraft is not well described by simple line vortex theory in the presence of a cross wind near the ground. Experimental observations indicate that the up-wind vortex usually drops to a lower altitude than the down-wind vortex. Figure 1 shows a photograph of this phenomenon where the vortex locations are marked by smoke from a tower. Figure 2 shows typical vortex tranjectorics measured with a pulsed acoustic ranging system developed at this center.
