Abstract
A wide range of unsteady phenomena of leading-edge vortices over stationary and dynamic slender delta wings were investigated. The origin, characteristics, and physical mechanisms of these unsteady phenomena and their role in buffeting were discussed. It was found that vortex breakdown, vortex interactions, and vortex shedding, play an important role in wing and fin buffeting, although vortex breakdown is the main source of buffeting over slender wings. With the requirement for high maneuverability and increasing wing flexibility for future unmanned air vehicles, unsteady vortex flow and vortex/structure interactions are expected to become more predominant.
