The Characterisation & Modification of Wakes from Lifting Vehicles in Fluids (La Caracterisation et la modification des Sillages Crees dans les Fluides par des Vehicules Portant),
Abstract
The aim of this symposium was to bring together researchers, engineers, and civil aviation representatives working in the field of aircraft wakes. Aircraft wake research has been supported by many organizations such as FAA, NASA, DLR, ONERA, aircraft manufacturers and others, and significant advances have been made in prediction, methodology, and experimental techniques. A review of the state-of-the-art was appropriate. The aircraft separation necessary to avoid the hazard of vortex encounters must be maintained despite the increasing number of airports and of commercial aircraft per airport. In addition, wakes are becoming more and more important in the detection of military aircraft. Techniques leading to a premature vortex decay or breakdown are of great interest. Economically efficient aircraft spacing requires an accurate prediction of vortex formation, evolution, decay and breakdown. Presentations focused on the following areas: (1) Regulatory Viewpoints, (2) Aircraft Spacing Considerations, (3) Vortex Wake Structure, (4) Vortex Instabilities and Breakdown, (5) Aircraft Vortex Interactions, and (6) Atmospheric Effects on Wakes. Currently, operators and regulators are concerned with improved detection and avoidance procedures as a means to allow reduced aircraft separation near airports. The fluid dynamics community can contribute by providing better approximate models of wake decay, better models of rolling moments for various generating aircraft, and better predictions and means of detecting vortex wakes.
