Ice accretion on unmanned air vehicle’s wing modifies the initial airfoil contour and changes the aerodynamic characteristic of the wing. The aim of this research is to calculate performance losses on a wing due to the accretion of rime ice. In this study, ice formation on NREL S826 airfoil is predicted by using ice accretion tool. The computed aerodynamic loads are compared for clean wings and iced wings with different aspect ratios. The computations are based on the lifting-line method. According to the results, predicted aerodynamic performance loss is higher for small aspect ratio than that of the bigger for the rime ice.
