Abstract
The asymmetric leeward-side flow-fields on slender bodies at high angle of attack are responsible for generation of side forces and phantom yaw moments at zero sideslip. A Navier-Stokes computational code is utilized for the investigation of mechanisms leading to the appearance of asymmetric vortices. In addition, the steady side force behavior at different roll orientation of the tip is examined for the purpose of identifying the source of vortex flow asymmetries.
