Abstract
An ice risk assessment model is developed to analyze the uncertainty in atmospheric circumstances and flying states throughout the aircraft icing process. The icing safety boundary is analyzed quantitatively by the model. The aerodynamic characteristics, such as lift, drag coefficient and moment, are calculated using numerical simulation to generate initial samples. This is done by slicing several swept-wing ice wind tunnel test models, based on the distribution characteristics of velocity, angle of attack, and pressure. The user inputs the geometric information, which includes the sweep angle and cross-section position. By utilizing the sensitivity analysis method and correlation analysis method, the study successfully determines the sensitivity of various icing parameters. Finally, a quantitative model is developed to assess the uncertainty of ice aerodynamics for the swept wing model.
