Abstract:

The use of a CW laser Doppler velocimeter (LDV) to study aircraft wake vortices began in 1969 (Ref. 1). This early development of the techniques culminated in measurements on wakes of landing aircraft at the John F. Kennedy International Airport in 1974 and 1975 (Ref. 2). These measurements involved aircraft at altitudes below 100 meters. In late 1975, a similar LDV system was used to measure wake velocity profiles from aircraft at altitudes up to 250 meters (Ref. 3). Based on this work, the Transportation Systems Center (TSC), under the sponsorship of the Federal Aviation Administration, developed a new scan pattern (Ref 4.) which yields good high-altitude vortex data, and is being used to collect data on the wakes of aircraft landing at Chicago's O'Hare International Airport.
