Abstract:

Three wake vortex measurement systems (anemometer, acoustic doppler, and laser

doppler) were used to collect wake vortex data from aircraft departing Runway 22L at

Chicago's O'Hare airport for nine months in 1980. The data were analyzed to determine

vortex decay and vortex transport probabilities. The results support the

classification of all B-707 and DC-8 aircraft in the large wake vortex class. The

acoustic doppler system was found to be significantly more sensitive than the ground

anemometer system to vortices transported long distances laterally by a crosswind.

The most efficient lateral transport was noted for crosswinds greater than seven

knots. The horizontal and vertical ground wind signatures of a wake vortex are

compared.
