Popis: An established reduced-frequency approach leveraging time-dependent 3D CFD-ALE simulations is used to calculate the static, quasi-static and dynamic stability derivatives of a clean and severely iced flying wing UAV at two angles of attack. Together with stationary 3D simulations, a quantitative assessment of changes to the flight behaviour can be made. The method can be used for any aircraft in any icing condition with minor limitations. The results show a severe degradation to some stability derivatives, especially in static longitudinal performance, whereas others are less affected and some even improved.
