【Abstract】 In some particular flight environment, ice is easy to adhere to the airfoil and change the aerodynamic configuration of the airfoil. Icing will influence the aerodynamic characteristics and flight performance of the airfoil. Thus it is very important to carry out the research on anti-icing and de-icing technologies of airfoil. The major parts of icing, representative ice types on the airfoil and the damage of icing are introduced respectively in this paper. The aerodynamic characteristics of airfoils NACA23012 and NACA0012 before and after icing are analyzed using the software of FLUENT. Based on them, the principle, advantage, disadvantage and research advances of airfoil anti- icing and de- icing technologies are expounded; The development of the airfoil anti- icing and de- icing technologies is also prospected.更多还原
