Aircraft Wake Vortex Takeoff Tests at O'Hara International Airport

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.
