Study on aerodynamic characteristics of ice accretion in different wing span sections

Aerodynamic characteristics of icing on different wing sections are one of the most important factors to be considered for designing anti/de-icing system.Wind tunnel routine force measure tests were carried out to obtain aerodynamic characteristics using simulation ice model on different wing sections of an airplane.Wing leading icing on different wing span sections would lead to different aerodynamic performance losses.Cruise and landing configurations were involved to study the lift,drag and pitch characteristics of the airplane.The results of the research showed that icing in the middle part of the wing lead to the greatest aerodynamic performance losses,and icing at the root and the tip of the wing leads to less aerodynamic performance losses which could be propitious to establish effective and efficient anti/de-icing system.
