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

摘要

A wing/canard configuration with sharp, highly swept leading edges was tested ina 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. Flow visualization, Water tunnel tests, Canard configurations, Leading edges, Vortex breakdown, Vortices.
