Visualisation in Water of Vortex Flow Over Sharp-Edged Canard Configurations

Abstract

A wing/canard configuration with sharp, highly swept leading edges was tested in a small towing tank. Flow visualisation techniques were used to study the effects of canard position on vortex interactions and vortex breakdown. A canard above or coplanar with the wing delayed wing vortex breakdown. A canard below the wing produced a strong interaction between the wing and canard vortices and could cause early wing vortex breakdown. Depending on its longitudinal position, the low canard could seriously disrupt the wingflow.
