Substantial advances in the analysis of the large-amplitude unsteady aerodynamics of wings have been achieved. Special focus has been placed on developing techniques for describing the exact non-linear convection, deformation, and roll-up of the vorticity wakes above and behind active wing surfaces. Using a combination of analytic and computer-interactive methods, new insights and more exact aerodynamic performance results have been generated. The effects of dissipative internal 'cores' in the overall 3D wake structures above deltas have been analyzed in the slender wing limit. New paths for further computer-assisted advances, including improved understanding of wingwake interaction in severe maneuver, vortex core formation and break-up, and aerodynamic history effects have been charted. Papers are included on the following topics: Nonlinear aerodynamics of two-dimensional airfoils in severe maneuver; Interactive aerodynamics of wings in severe maneuver; Slender wing theory including regions of embedded total pressure loss.
