This work presents a methodology for computing unsteady aerodynamic loads in the transonic regime within the context of preliminary aircraft design. The unsteady pressure loads are obtained using a Source and Doublet Panel Method and are corrected by means of Viscous-Inviscid Interaction, whereby a steady transonic full potential solver is coupled with the integral boundary layer equations.
