Dutch-roll motions caused by sudden gusts are studied for a typical advanced air mobility vehicle. The selected lift + cruise configuration consists of a fuselage with high wing powered by lifting and pushing propellers. Flow is modeled using the Navier–Stokes equations. A procedure is developed to embed the Dutch-roll motion equations in an overset grid topology along with rotating blades. Results are validated with lifting line theory computations and experiments. A typical Dutch-roll stability scenario is demonstrated by time-accurately integrating trajectory equations with the flow equations. The present work extends the capabilities of the current Navier–Stokes solvers to design urban air taxi configurations.
