• Abstract:
  A wake vortex transport model has been developed which includes the effects of wind and wind
  
  shear, buoyancy, mutual and self-induction, ground plane interaction, viscous decay, finite core
  
  and Crow instability effects. Photographic and ground-wind vortex tracks obtained from DC-6, B-
  
  747, B-707, and CV-880 aircraft flybys are compared with predicted vortex tracks computed using meteorological
  
  and aircraft data as inputs to the transport model. A parametric analysis of the effects
  
  of the aircraft, fluid mechanic, and meteorological parameters shows the relative magnitude of each
  
  transport mechanism. The study constitutes the first detailed comparison of vortex transport theory
  
  with experimental data.
