In order to study the influence of ice accretion, in this paper, the equations of motion of water droplets are established by Lagrange method. The mass and energy balance equations are solved by Messinger model. The predicted curves are compared with the experiment curves, and the results are consistent. The influence of flight parameters and atmospheric parameters on the results of icing on the surface, indicate that the ice-type changes are caused by flight speed. Other parameters such as icing time and LWC affect the amount of icing, but little effect on the ice type. Icing on the surface makes the roughness of the lifting surface increase and the characteristics of lift and drag of airfoil deteriorate significantly. By studying the aerodynamic characteristics of the airfoil after icing, the results show that the lift coefficient significantly decreases and the drag coefficient increases with the icing time increasing. Under the same conditions, increasing the flight speed can significantly improve the aerodynamic characteristics of the aircraft.
