This study evaluates the operational limitations of a HALE UAVs by simulating the entire airframe, including the propeller, in an icing environment. Two-dimensional (BEMT) and three-dimensional (MRF) analyses are performed to predict propeller icing and analyze its aerodynamic effects. The conclusions highlight the impact of propeller icing on the operational limits of HALE UAVs.
