Abstract : Simulations of wingrock with an additional degree of freedom have been completed and a new technique to simulate the unsteady wake behind an airfoil was developed. An analytical model of the subsonic wingrock phenomenon for a slender wing has been completed and a numerical simulation of the interference between the leading and trailing wings of an X-29 model have been developed further. Keywords: Computerized; Simulation; Slender delta wings; Wingrock; Unsteady wake; Unsteady aerodynamics.
