Simulation of Wake Vortices Descending in a Stably Stratified Atmosphere.

Abstract

An experimental water tank simulation of aircraft wake vortices descending in a stable atmosphere has indicated that the atmospheric stability stops the downward movement and in some cases produces a subsequent rebound. The tests were carried out in a large ship model basin using a rectangular planform wing. Lift coefficients were selected, and stable atmospheric conditions were obtained by temperature (density) stratification of the towing basin. The model parameters and stability conditions cover the most extreme cases to be expected in full scale flight.
