In order to investigate the effects of ice on aircraft performance, the RAE2822 airfoil is introduced. Using the FLUENT software, the lift coefficient and drag coefficient of RAE2822 airfoil with different types of ice have been calculat-ed and the flow of airfoil icing are analyzed. Its shows that the ice changes the wing shape, and leading the flow separation occurs in advance, so the aircraft aerodynamic performance affected.
