A mathematical model was developed to both describe an airfoil electrothermal anti-ice system operation and enable prediction of its main parameters. A reference case was chosen to define the mathematical model and support the results validation. The

Various classic icing codes have been developed and used by the aircraft manufacturers to predict the ice shapes evolution in non-protected airfoil surfaces. These codes apply boundary layer integral analysis, based on sand grain roughness, to estima

Under icing conditions, it is necessary to heat and control the temperature of the airfoil surface at leading edge region to prevent ice formation. The thermal anti-ice system balances mainly the evaporative cooling effects, which are caused by the c
