Abstract
A vortex located in a junction of wing-body configuration decreases the overall performance and stability of an aircraft. To eliminate this detrimental phenomenon, this study dealt with an installation of the vortex generator on the wing surface and the body surface, and the parametric study for the position of the vortex generator was performed. By adopting the results of this parametric study, a design optimization of vortex generator was also conducted. Because this design included a large number of design variables to consider each vortex generator individually, adjoint based sensitivity analysis for the gradient based design optimization was adopted. As a result, the aerodynamic performance of the target aircraft was substantially over 5%, and the junction vortex was shrunk and weakened enough.
