Abstract : The Fluid Dynamics Panel of AGARD arranged a Symposium on 'The Characterization and Modification of Wakes from Lifting Vehicles in Fluids,' on 20-23 May 1996 in Trondheim, Norway. The purpose of the Symposium was to review and discuss recent developments in wake research for aircraft and the implications for air traffic regulations, with a clear emphasis on the hazard of vortex encounters in civil aviation. Sessions were devoted specifically to operational procedures and aircraft spacings in airport terminal areas; to the aerodynamic interactions between trailing vortices and following aircraft; to trailing vortex structures, instabilities, atmospheric effects on wakes, and vortex breakdown; and to miscellaneous issues, such as vortices generated by other vehicles and the interactions between vortex wakes and engine exhausts. The Symposium was unclassified, and it was rather unusual with respect to the broad range of interests of the active participants: representatives of regulatory agencies; aircraft manufacturers and operators; and research scientists engaged in flight tests, flight simulations, and basic experimental and theoretical fluid dynamics. Thirty-seven papers were presented at the meeting. An overview of the Symposium and some general conclusions and recommendations are given in this Evaluation Report.
