Ice accretion on the UAV’s wing profile 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. The computations are based on the Lifting line method in order to predict the aerodynamic performance of both iced and clean wings for different aspect ratios. Currently, ice formation on NREL S826 airfoil is predicted by using ice accretion tool and computed aerodynamic loads compared with clean and iced wing profiles for different aspect ratios. It is seen that predicted aerodynamic performance loss is higher for small aspect ratio than that of the bigger for the rime ice.
